Cellular Resperation
Bio Test Part 1
| Question | Answer |
|---|---|
| What is the chemical equation for cellular respiration? | C6H12O6+6O2 yields to 6CO2 + 6H2O + ATP |
| Where does glycolysis take place? | cytoplasm |
| Is glycolysis aerobic or anaerobic? | both |
| Where does Krebs Cycle take place? | matrix |
| Is the Krebs Cycle anaerobic or aerobic? | aerobic |
| Where does the ETC take place? | cristae |
| Is the ETC anaerobic or aerobic? | aerobic |
| (Def.) Aerobic | with oxygen |
| (def.) anaerobic | without oxygen |
| What is the reactant in gycolysis? | glucose |
| What is the product in glycolysis? | pyruvate & NADH & 2 ATP |
| What two groups does pyruvate split into? | anaerobic and aerobic |
| What is another name for anaerobic respiration? | fermentation |
| What are two types of fermentation? | alcoholic fermentation and lactic acid fermentation |
| What is the chemical formula for alcoholic fermentation? | pyruvic acid + NADH yields to alcohol + CO2 + NAD+ |
| When does alcoholic fermentation happen? | happens when yeast makes beer or bacteria makes wine |
| What is the chemical equation for lactic acid fermentation? | pyruvic acid + NADH yields to lactid acid + NAD+ |
| When does lactic acid happen? | happens in muscles during exercise when the body can't get oxygen enough oxygen to the tissues fast enough (carries lactid acid through the muscles as a result) & happens when bacteria used to make food |
| How does lactic acid react with muscles? | Lactic acid builds up in muscles causing soreness |
| Ex of lactic acid foods | cheese,yogurt, buttermilk, sauerkrout, pickles, sour cream, & kimchi |
| What does pyruvate react with when it enters the Kreb Cycle? | coenzyme A (CoA) |
| What does pyruvate and CoA form when they react? | acetyl CoA |
| Where does the acetyl CoA go & what does it react with once it gets there? | acetyl CoA goes to Mitochondria & acetyl CoA reacts with oxaolacitic acid |
| When acetyl CoA reacts with oxaloacetic acid what does it make? | citric acid |
| What is the product of the Krebs Cycle? | Carbon Dioxide |
| What is sent to the ETC from the the Krebs Cycle? | NADH & FADH2 |
| What does NADH turns to? | NAD+ |
| What does FADH2 turns to? | FAD+ |
| FADH2 turns hydrogen ions in the ETC and converts what into what? | FADH2 turns hydrogen ions in the ETC and converts oxygen into water |
| When hydrogen ions build up in the intermembrane space where does it diffuse through? | ATP Synthase |
| What happens after hydrogen ions pass through ATP Synthase? | Turns 32 ADP molecules to 32 ATP molecules |
| What is added after 32 ADP molecules turns to 32 ATP molecules? | Adds H2O to turn to 36 ATP molecules |
| What are the electron carriers? | NAD+ and FAD |
| What does alcoholic fermentation produce? | ethonol |
| Does alcoholic fermentation produce a lot of ATP? | NO |
