6125125219G2In which subphase of interphase are the chromosomes duplicated?10
6125125220prophase-first stage of mitosis -spindle fibers start to forms -nucleus thins -sister chromatids combine to make chromosomes11
6125125221prometaphase-second stage of mitosis -the nuclear envelope fragments -the spindle microtubules attach to the kinetochores of the chromosomes12
6125125222metaphase-third phase of mitosis -chromosomes line up in the center of the cell -spindle fibers attach to the kinetochores of each sister chromatid13
6125125223anaphase-fourth phase of mitosis -sister chromatids separate and move toward opposite ends of the cell14
6125125224telophase-fifth and final stage of mitosis -genetically identical daughter nuclei form at opposite ends of the cell -nonkinetochore microtubules from opposite poles overlap and push each other elongating the cell15
6125125225mitotic spindle-apparatus of microtubules that control chromosome movement during mitosis16
6125125226centrosome-microtubule organizing center -replicates, each set goes to opposite ends -spindle fibers grow out from them17
6125125227kinetochores-protein complexes that assemble on sections of DNA at centromeres -where spindle fibers and microtubules attach18
6125125228metaphase plate-midway point between the spindles two poles -where chromosomes line up in metaphase19

6125125231binary fission-prokaryotic method of reproduction and cell division -chromosome replicates and the two daughter chromosomes actively more apart22
6125125233checkpoints-where the cell cycle stops until a go ahead signal is received -G1 is the most important for many cells23
6125125234G0-the nondividing stage of the cell if it does not pass the G1 checkpoint24
6125125235growth factorsproteins released by certain cells that stimulate other cells to divide25

612512524246What is the chromosome number for humans?31
6125125243homologous chromosomes-2 chromosomes in each pair -same length and shape -carry genes controlling the same inherited characters32
6125125244diploid cell-has two sets of chromosomes -human # is 46 -2n33
6125125245haploid-gamete -contains a single set of chromosomes -n34
6125125246fertilizationthe union of gametes (sperm and egg)35
6125125247zygote-fertilized egg -one set of chromosomes from each parent -diploid cell produces somatic cells by mitosis36
6125125248prophase I-occupies more than 90% of the time required for meiosis -chromosomes condense -synapse and crossing over -tetrads and chiasmata37
6125125249synapsis-homologous chromosomes loosely pair up -align gene by gene -get together with homologous pair38
6125125250crossing overnonsister chromatids exchange DNA segments39
6125125251metaphase Ihomologous pairs line up in the middles of the cell and the spindle fibers attach to them40
6125125252anaphase I-chromosomes move toward each pole -sister chromatids move as one unit toward the pole41
6125125253telophase I-beginning: each half of the cell has a haploid set of chromosomes -each chromosome consists of two sister chromatids42
6125125254prophase IIspindle apparatus forms43
6125125255metaphase II-because of crossing over the sister chromatids are no longer genetically identical -kinetochores of sister chromosomes attach to microtubules extending from opposite poles44
6125125256anaphase II-sister chromatids of each chromosome move as two newly individual chromosomes toward opposite poles45
6125125257telophase II-chromosomes arrive at opposite poles -nuclei form and the chromosomes begin decondensing46
6125125258independent assortment of chromosomes-mechanism contributing to genetic variation -homologous pairs of chromosomes orient randomly -metaphase I -each pair of chromosomes sorts maternal and paternal homologs into daughter cells independently of the other pairs -the number of combinations possible when chromosomes assort independently into gametes is 2^n where n is the haploid number47
6125125259crossing over-mechanism contributing to genetic variation -produces recombinant chromosomes -begins in early prophase I -homologous chromosomes pair up gene by gene -homologue portions of two nonsister chromatids trade places -combines DNA from two parents into a single chromosome48
6125125260random fertilization-any sperm can fuse with any ovum -the fusion of two gametes produces a zygote with any of about 70 trillion diploid combinations -each zygote has a unique genetic identity49

Cellular Respiration: Harvesting Chemical Energy

Terms : Hide Images
5760114767Fermentation-catabolic process that partially degrades sugars w/o oxygen -expansion of glycolysis that allows continuous generation of ATP by substrate-level phosphorylation of glucose -regenerates NAD+ by transferring electron from NADH to pyruvate -produce ATP by harvesting chemical energy of food -use glycolysis to oxidize glucose and other organic fuels to pyruvate-net production of 2 ATP w/ substrate level phosphorylation -NAD+ is oxidizing agent that accepts electrons from food in glycolysis -final electron acceptor is organic molecule0
5760114768Aerobic Respiration-oxygen consumed as reactant along w/ organic fuel -prokaryotes and eukaryotes -produce ATP by harvesting chemical energy of food -use glycolysis to oxidize glucose and other organic fuels to pyruvate-net production of 2 ATP w/ substrate level phosphorylation -NAD+ is oxidizing agent that accepts electrons from food in glycolysis -final electron acceptor is NADH is oxygen-regenerates NAD+ for glycolysis, pays ATP bonus when electron transport from NADH -> O2 drives oxidative phosphorylation -citric acid cycle-oxidation of pyruvate bigger ATP pay off -19x more energy/sugar molecule1
5760114769Anaerobic Respiration-process of using substances other than oxygen as reactants to harvest chemical energy w/o oxygen -use electron transport chain but don't use oxygen as final electron acceptor2
5760114770Cellular Repsiration-process for animal to breathe oxygen; aerobic + anaerobic -C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP + heat)3
5760114771Redox Reactionsreactions w/ electron transfer4
5760114772Oxidationloss of electrons from one substance5
5760114773Reductionaddition of electrons to another substance6
5760114774Reducing Agentelectron donor7
5760114775Oxidizing Agentelectron acceptor8
5760114776NAD+-coenzyme electron acceptor -oxidizing agent in respiration9
5760114777Glycolysis-begins degradation process by breaking glucose into 2 pyruvate molecules +2 ATP w/ substrate-level phosphorylation10
5760114778Citric Acid Cycle-completes breakdown of glucose by oxidizing pyruvate to CO2 -CO2 produced represents fragments of oxidized organic molecules -takes place in mitochondrial matrix (eukaryotic) /cytosol (prokaryotic) +2 w/ substrate-level phosphorylation11
5760114779Acetyl CoAjunction between glycolysis and citric acid cycle 1. pyruvate's carboxyl group (-COO-) removed and given of as molecule of CO2 2. remaining 2-carbon fragment oxidized -> acetate. enzyme transfers extracted electrons to NAD+, storing energy in form of NADH 3. coenzyme A attached to acetate by unstable bond that makes acetyl group very reactive -> acetyl CoA has high potential energy-reaction to yield lower energy products is highly exergonic12
5760114780Oxidative Phosphorylation-mode of ATP synthesis powered by redox reactions in electron transport chain-energy released at each step of chain stored in form for mitochondria -90% of ATP generated +32-34 ATP by oxidative phosphorylation13
5760114781Electron Transport Chainbreaks fall of electrons to oxygen in energy releasing steps -consists of molecules (proteins) in inner membrane (eukaryote)/plasma membrane (prokaryote)14
5760114782Cytochromesmost of remaining electron carriers15
5760114783ATP Synthase-enzyme in inner membrane of mitochondrion that makes ATP from ADP and inorganic protein -ion pump running in reverse -uses energy of existing ion gradient to power ATP synthesis16
5760114784Chemiosmosis-process in which energy stored as H+ gradient across membrane used to drive cellular work like ATP synthesis -protons move one by one to binding sites of ATP synthase -> spins in way to catalyze production of ATP from ADP and inorganic phosphatwe17
5760114785Substrate-Level Phosphorylationmode of ATP synthesis when enzyme transfers phosphate group from substrate molecule to ADP, rather than adding inorganic phosphate to ADP18
5760114786Proton-motive ForceH+ gradient and its capacity to do work19
5760114787Alcohol Fermentation-pyruvate converted to ethanol 1. CO2 released from pyruvate-converted to 2-carbon acetaldehyde 2. acetaldehyde reduced by NADH to ethanol-regenerates supply of NAD+ for glycolysis20
5760114788Lactic Acid Fermentation-pyruvate reduced directly by NADH -> form lactate w/ no release of CO2 -sugar catabolism for ATP production outpaces muscle's supply of oxygen -> cells switch from aerobic respiration to fermentation21
5760114789Obligate Anaerobesorganisms that only carry out fermentation or anaerobic respiration-cannot survive in presence of oxygen22
5760114790Facultative Anaerobes-make enough ATP to survive using fermentation or respiration -pyruvate -> 2 alternative catabolic rates -aerobic conditions: pyruvate -> acetyl CoA-oxidation continues in Krebs Cycle -anaerobic conditions: pyruvate diverted from Krebs Cycle-serves as electron acceptor to recycle NAD+ - has to consume sugar at faster rate23

6156802557James MarciaStudied the different ways that adolescents handle commitment and cope with identity crisis Identity Status Theory; The first identity status, identity diffusion, describes youth who have neither explored nor committed to any particular identity. Thus, this identity status represents a low level of exploration and a low level of commitment. The second identity status is the identity foreclosure status. This identity status represents a low degree of exploration but a high degree of commitment. At this identity status adolescents are not actively trying to determine what is important to them. The third identity status is called moratorium. This identity status represents high degree of exploration but a low degree of commitment. At this status, youth are in the midst of an identity "crisis" which has prompted them to explore and experiment with different values, beliefs, and goals. The final identity status is identity achievement. This identity status represents both a high degree of exploration and a high degree of commitment. Youth are said to have achieved their identity by a process of active exploration and strong commitment to a particular set of values, beliefs, and life goals that has emerged from this active exploration and examination.65
