Cellular Respiration Stage 4: Electron Transport Chain Cellular respiration What?s the point? The point is to make ATP! ATP ATP accounting so far? Glycolysis ? 2 ATP Kreb?s cycle ? 2 ATP Life takes a lot of energy to run, need to extract more energy than 4 ATP! A working muscle recycles over 10 million ATPs per second There?s got to be a better way! I need a lot more ATP! There is a better way! Electron Transport Chain series of proteins built into inner mitochondrial membrane along cristae transport proteins & enzymes transport of electrons down ETC linked to pumping of H+ to create H+ gradient yields ~36 ATP from 1 glucose! only in presence of O2 (aerobic respiration) O2 That sounds more like it! Mitochondria Double membrane outer membrane inner membrane

Let?s begin with a review of several terms that you may already know. Define: gene: A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses) locus: A specific place along the length of a chromosome where a given gene is located gamete: A haploid reproductive cell, such as an egg or sperm. Gametes unite during sexual reproduction to produce a diploid zygote. male gamete: Sperm female gamete: Eggs

Copyright ? 2011 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 12: The Cell Cycle Overview: 1. What are the three key roles of cell division? State each role, and give an example. Key Role Example Reproduction An amoeba, a single-celled eukaryote, divides into two cells. Each new cell will be an individual organism. Growth and development A sand dollar embryo forms two cells shortly after the fertilized egg is divided. Tissue removal Dividing bone marrow cells will give rise to new blood cells. 2. What is meant by the cell cycle? The cell cycle is the life of a cell from the time it is first formed from a dividing parent cell until its own division into two daughter cells.

CHAPTER 8 An Introduction to Metabolism Metabolism is the totality of an organism?s chemical reactions Manage the materials and energy resources of a cell Catabolic pathways release energy by breaking down complex molecules into simpler compounds Eg. digestive enzymes break down food ? release energy Anabolic pathways consume energy to build complex molecules from simpler ones Eg. amino acids link to form muscle protein ENERGY = CAPACITY TO DO WORK Kinetic energy (KE): energy associated with motion Heat (thermal energy) is KE associated with random movement of atoms or molecules Potential energy (PE): stored energy as a result of its position or structure Chemical energy is PE available for release in a chemical reaction Energy can be converted from one form to another

Meiosis v. Mitosis Ploidy Non disjunction Definitions Mitosis - the way normal body cells divide, reproduce, and grow...and meisosis extends it one step further. In meiosis the cell grows larger. THey both divide into 2 seperate cells but in meiosis, the steps continue - the resulting cells divide further into meiosis. WHen cells undergo meiosis, the result is the creation of gametes, sex-cells. It involves one replication of chromosones and 2 successive cell divisions. Mitosis - starts our all diploid and then it splits into Haploid. Non disjunction - chromosomes fail to separate correctly.
