| Question | Answer |
|---|---|
| cellular respiration | the complext process in which cells make adenosine triphosphate (ATP) by breaking down organic compounds |
| fermentation | the combination of glycolysis and these additional pathways, which regenerate NAD+ do not produce ATP |
| lactic acid fermenation | an enzyme converts pyruvic acid made during glycolysis into another three-carbon compound called lactic acid |
| alcoholic fermentation | some plant cells and unicellular organisms such as yeast use this process |
| kilocalories | 1000 calories |
| glycolysis | organic compounds are converted into three-carbon molecules of pyruvic acid producing a small amount of ATP and NADH. an anaerobic process |
| pyruvic acid | prodces small amounts of ATP |
| NADH | an electron carrier molecule |
| anaerobic | a proccess that does not require the presence of oxygen |
| aerobic respiration | oxygen present in the cell's environment, breaks down pyruvic acid and NADH is used to make ATP |
| NAD+ | nicotinamide adenine dinucleotide |
| mitochondrial matrix | the space inside the inner membrane of a mitochondrion. |
| acetyl CoA | When pyruvic acid enters the mitochondrial matrix and reacts with coenzyme A to form acetyl coenzyme A |
| Krebs cycle | a biochemical pathway that breaks down acetyl CoA producing CO2, hydrogen atoms, and ATP |
| oxaloacetic acid | two carbon molecule of acetyl CoA combines with a 4-carbon compound |
| citric acid | six-carbon compound |
| FAD | flavin adenine dinucleotide similar to NAD+ |
