Bio Ch9 Cellular Respiration
| Term | Definition |
|---|---|
| Who does cellular respiration? | ALL eukaryotic cells & some prokaryotic cells! Because ALL cells need energy! |
| Where do organisms perform cellular respiration? | the mitochondria |
| What's needed for cellular respiration? | Glucose (food), oxygen, enzymes, The Helpers |
| Cellular Respiration – The Reaction | glucose plus oxoygen = carbon dioxide plus water |
| What's made in cellular respiration? | carbon dioxide (released as waste), water, ATP (used in cell) |
| What is ATP from cellular respiration used for? | Cells use the energy for: synthesis, active transport, reproduction, movement, maintaining, homeostasis |
| What factors affect cellular respiration? | Temperature, enzymes are needed for CR Glucose concentration in cell/body Oxygen availability |
| What happens to human cells if oxygen isn’t available? | Human cells go through lactic acid fermentation Cells produce ATP until oxygen becomes available again |
| Lactic acid fermentation - who does it? | Some bacteria, some fungi, and animals (sometimes) |
| Where does lactic acid fermentation take place? | cytoplasm |
| What's needed for lactic acid fermentation? | glucose |
| What’s made from lactic acid fermentation? | Small amount of ATP |
| Examples of lactic acid fermentation? | Bacteria use this to make yogurt In humans, causes burning sensation in muscles |
| Who does alcoholic fermentation ? | yeast |
| Where does alcoholic fermentation take place ? | cytoplasm |
| What's needed for alcoholic fermentation ? | glucose |
| What's produced from alcoholic fermentation ? | Small amount of ATP, carbon dioxide, alcohol |
| Examples of alcoholic fermentation? | Used to make bread, beer, & wine Carbon dioxide bubbles make holes in bread |
