6369070472Biochemical PathwayA series of chemical reactions in which the product of one reaction is consumed in the next reaction. For example, NADH is produced in the Kreb's Cycle and then utilized in the Electron Transport Chain0
6369085779ATPMolecule used for cellular energy to maintain homeostasis and work1
6369091070FermentationA process in which cells make a limited number of ATP by converting glucose into another organic compound such as lactic acid or ethyl alcohol and carbon dioxide without the use of oxygen2
6369115142Electron Transport ChainA series of protein molecules that transports electrons and protons through the inner membrane of the mitochondria. In the process the energy is used to: 1-pump protons into the inner membrane space, 2-generate ATP as H+ move through ATP synthase3
6369143752ChemiosmosisA process of ATP generation. The movement of electrons down an electron transport system is used to pump hydrogen ions across a membrane, thereby building up a concentration gradient of hydrogen ions across the membrane. The hydrogen ions diffuse back across the membrane through the pores of a ATP synthesizing enzymes. The energy of their movement down their concentration gradient drives ATP synthesis.4
6369157439ADP (adenosine diphosphate)Resulting molecule when ATP removes a phosphate group and releases energy.5
6369168000ATP synthaseAn enzyme that catalyzes the synthesis of ATP from ADP and phosphate by catalyzing the linking together of the two molecules6
6369174757ReactantA compound or atom involved in a chemical reaction7
6369180687ProductA compound formed by a chemical reaction8
6369185032GlycolysisA pathway not requiring oxygen (but can proceed when oxygen is present) in the cytoplasm in which glucose is broken down into 2 pyruvate, 2 NADH, and 4ATP (net gain of 2 ATP)9
6369195574Pyruvate3-carbon molecule that is the end product of glycolysis and that enters into the Kreb's Cycle10
6369206257Anaerobic RespirationThe process in which cells make ATP breaking down organic compounds without the use of oxygen11
6369212487Aerobic RespirationThe process in which cells make ATP by breaking down organic compounds, with oxygen as the final electron acceptor12
6369218890Cellular RespirationThe process in which cells make ATP by breaking down organic compounds -- in eukaryotes this process occurs in the mitochondria13
6369229442Kreb's Cycle (aka) Citric Acid CycleThe second major step of cell respiration that occurs in the mitochondria. During the cycle, the break down of acetyl CoA occurs (2 Carbon compound) to form electron carriers 6 NADH & 2 FADH2 as well as producing 2 ATP and 4 carbon dioxide14
6369706807NAD+ and FADElectron carriers that will move electrons to the Electron Transport System for ATP production during chemiosmosis15
6369720611Lactic Acid FermentationThe product formed in the cytosol of muscle cells and in some bacteria during fermentation (anaerobic fermentation)16
6370079485Alcoholic FermentationType of cellular Respiration which does not require oxygen (anaerobic respiration), and involves the breaking down of pyruvate to ethanol and carbon dioxide.17
6374507404CytochromeSeries of proteins found in the inner membrane of the mitochondria that function as electron transfer agents during cellular respiration.18
6374525511matrixThe fluid filled enzyme rich area found within the inner membrane that is the site of the Kreb's Cycle.19
6374596920NAD+ / NADHNictinamide adenine dinucleotide, A coenzyme that can accept an electron and acts as an electron carrier in the electron transport chain20
6374612011FAD /FADH2Flavin adenine dinucleotide, or FADH2 that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain.21
