Cellular Respiraiton Facts
| Question | Answer |
|---|---|
| All living things begin the breakdown of glucose with this process. | Glycolysis |
| Glycolysis needs these 2 things to keep going. | ATP and NAD+ |
| The net gain of ATP from glycolysis is this? | 2 |
| By the end of glycolysis, glucose has been broken down into this. | 2 pyruvic acid |
| Aerobic respiration uses this to break down glucose. | oxygen |
| What are the 2 types of anaerobic respiraiton | lactic acid and alcoholic fermentation |
| In lactic acid fermentation, this is regenerated. | NAD+ |
| What does lactic acid do to muscles? | makes them sore |
| What 2 things are byproducts of alcoholic fermentation? | carbon dioxide and alcohol |
| What causes bread to rise? | carbon dioxide |
| What does alcoholic fermentation regenerate? | NAD+ |
| What part of the cell does fermentation take place in? | cytoplasm |
| What part of the cell does glycolysis take place in? | cytoplasm |
| What part of the cell does the kreb cycle take place in? | mitochondria (matrix) |
| How much ATP is produced during the Kreb's Cycle? | 2 ATP |
| How many carbon dioxide molecules are released during the Kreb's Cycle? | 6 |
| What 2 energy carrier molecules are created by the Kreb's Cycle? | FADH2 and NADH |
| Where does electron transport occur? | cristae of mitochondria |
| How many molecules of ATP are made during the Kreb's Cycle? | 2 |
| What 2 molecules move from the Kreb's Cycle to electron transport? | NADH and FADH2 |
| What is the final electron acceptor in electron transport? | oxygen |
| What happens if the mitochondria runs out of oxygen during electron transport? | process shuts down, human cells switch to lactic acid fermentation |
| How many ATP molecules are made during electron transport? | 32 |
| How many ATP molecules are produced from 1 glucose molecule when oxygen is used? | 36 |
