1. cellular respiration is the process by which cells convert_____into energy.
2. the organelle associated with cellular respiration is the_____.
3. the chemical equation for cellular respiration is:

glucose + oxygen→___+___+atp

1. the function of cellular respiration is to produce_____, the cells energy currency.
2. anaerobic respiration is a type of cellular respiration that does not require_____.
3. during glycolysis, a molecule of glucose is broken down into two molecules of_____.

7._____is a type of anaerobic respiration that occurs when there is not enough oxygen available.

1. yeasts produce this product during fermentation:_____.
2. humans undergo_____fermentation when muscles dont have enough oxygen.
3. the first stage of cellular respiration is_____.
4. the second stage of cellular respiration is the_____cycle.
5. the third stage of cellular respiration is the_____transport chain.
6. the majority of atp is produced in the third stage, through_____phosphorylation.
7. atp_____is a protein that uses the proton gradient in the etc to make atp.

Explanation:

1. Cellular respiration converts glucose into energy.
2. Mitochondria are the organelles for cellular respiration.
3. The equation is Glucose + Oxygen → Carbon dioxide + Water + ATP.
4. ATP is the cell's energy currency.
5. Anaerobic respiration doesn't need oxygen.
6. Glycolysis breaks glucose into pyruvate.
7. Fermentation is anaerobic without enough oxygen.
8. Yeasts produce ethanol during fermentation.
9. Humans have lactic acid fermentation in muscles.
10. Glycolysis is the first stage.
11. The second stage is the Krebs cycle.
12. The third stage is the electron transport chain.
13. Oxidative phosphorylation produces most ATP.
14. ATP synthase uses the proton gradient.
