| Question | Answer |
|---|---|
| what is cellular respiration? | process of breaking down organic compounds to produce ATP |
| what are the 2 stages of cellular respiration? | glycolysis and aerobic or anaerobic respiration |
| where does glycolysis take place? | in the cytosol |
| what is formed through glycolysis? | pyruvic acid (pyruvate) |
| how many ATP does glycolysis make? | 4 (2 in total, takes in 2 and gets 4 out) |
| how many ATP does glycolysis take in? | 2 |
| what is the electron carrier in glycolysis? | NAD+ |
| is fermentation anaerobic or aerobic? | anaerobic |
| what does anaerobic mean? | does not have oxygen |
| what does aerobic mean | has oxygen |
| does fermentation produce ATP | no |
| what does fermentation regenerate that allows for continued production of ATP through glycolysis? | NAD+ |
| what happens in lactic acid fermentation? | an enzyme converts 3c pyruvic acid into another 3c compound called lactic acid |
| where does lactic acid fermentation take place? | muscle cells |
| what happens during alcohol fermentation? | 3c pyruvic acid is changed into 2c ethyl alcohol and CO2 |
| what organisms do alcohol fermentation? | some plants and unicellular organisms such as yeast and bacteria |
| what does alcohol fermentation make? | beer, wine, bread, cheese, yogurt, sour cream, vinegar |
| what % of energy available from oxidation of glucose is captured by ATP? | 2% |
| are glycolysis and fermentation efficient at making ATP? | no |
| where does aerobic cellular respiration take place? | in the mitochondria |
| where does the Krebs cycle take place? | mitochondrial matrix |
| where does the ETC and chemiosmosis take place? | cristae |
| what happens during the intermediate step? | 3c pyruvic acid produced in glycolysis reacts with coenzyme A to form Acetyl CoA (2c) |
| what are the products of the intermediate step? | CO2, NADH, and acetyl CoA |
| what is formed from the Krebs cycle? | 6c citric acid |
| how many turns of the Krebs cycle does it take to break down citric acid? | 1 |
| why does the Krebs cycle turn 2x? | because there are 2 acetyl CoA |
| what are the products of the Krebs cycle? | 2 ATP, 6 CO2, 8 NADH, and 2 FADH |
| what happens during ETC and chemiosmosis? | high energy electrons in NADH and FADH2 are passed from molecule to molecule in the ETC in cristae |
| what ions do NADH and FADH2 give up into the intermembrane space? | H+ ions |
| how many ATP are produced during ETC and chemiosmosis? | 32-34 |
| how much more efficient is aerobic respiration than glycolysis and fermentation? | 20 x more efficient |
