cell respiration
| Question | Answer |
|---|---|
| cellular respiration | process that releases ATP by breaking down glucose |
| steps of aerobic respiration | Kreb's cycle and electron transport chain |
| glycolysis | first stage of anaerobic cell respiration. Breaks down glucose into 2 pyruvic acid molecules, net gain of 2 ATP |
| alcoholic fermentation | type of anaerobic respiration used by organism such as yeast to recycle NAD+. alcohol and carbon dioxide are made |
| lactic acid fermentation | type of anaerobic respiration used by organism such as humans and bacteria to recycle NAD+. used in making yogurt and cheese |
| location of glycolysis | cytoplasm |
| ATP | adenosine triphosphate, cellular energy |
| pyruvate or pyruvic acid | 3 carbon sugar produced when glucose is split during glycolysis |
| mitochondria | site of aerobic cellular respiration |
| ATP synthase | enzyme that helps make ATP during the electron transport chain |
| another name for Krebs cycle | citric acid cycle |
| Krebs cycle | produces carbon dioxide, NADH and FADH2. net gain of 2 ATP |
| Electron Transport Chain | takes NADH, FADH2, and oxygen to make water and 34 ATP |
| cellular respiration chemical equation | glucose + oxygen yields carbon dioxide + water + ATP |
| purpose of fermentation | to regenerate NAD+ so glycolysis can continue |
| location of Krebs and electron transport chain | mitochondria |
