101363417catabolismbreakdown of more complex substances into simpler ones with release of energy
101363418aerobic respirationcellular respiration that uses oxygen, sequentially releasing energy and storing it in ATP
101363419Anaerobic respirationThe use of inorganic molecules other than oxygen to accept electrons at the "downhill" end of electron transport chains.
101363420FermentationA catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid.
101363421Substrate-level phosphorylationa process in which produces ATP. Occurs during glycolysis and the Krebs cycle.
101363422glycolysisfirst step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid
101363423NAD+Nicotinamide adenine dinucleotide, a coenzyme present in all cells that helps enzymes transfer electrons during the redox reactions of metabolism., (electron carrier involved in glycolysis)
101363424acetyl-CoAthe Krebs cycle begins and ends with _____, Forms when pyruvic acid reacts with the enzyme CoA
101363425Kreb's cyclesecond stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
101363426electron-transport chainTransfer of electrons from one to another- used to make ATP from Oxidation Phosphoralation
101363427chemiosmosisAn energy-coupling mechanism that uses energy stored in the form of a hydrogen ion gradient across a membrane to drive cellular work, such as the synthesis of ATP. Most ATP synthesis in cells occurs by chemiosmosis.
101363428ATP synthaselarge protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP
101363429deaminationremoval of the amino radical from an amino acid or other amino compound
101363430beta-oxidationbreaks fatty acids into 2 carbon fragments which become acetyl CoA and enter the Kreb's cycle
101363431ethanol fermentationA type of yeast anerobic metabolism in which pyruvate is converted into ethanol and carbon dioxide for the purpose of regenerating NAD+ to keep glycolysis going and at least yield 2 net ATP.
101363432lactic acid fermentationseries of anaerobic chemical reactions in which pyruvic acid uses NADH to form lactic acid and NAD+, which is then used in glycolysis; supplies energy when oxygen for aerobic respiration is scarce
