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 ______________.
4. ______________ is a type of anaerobic respiration that occurs when there is not enough oxygen available.
5. yeasts produce this product during fermentation: ______________.
6. humans undergo ______________ fermentation when muscles dont have enough oxygen.
7. the first stage of cellular respiration is ______________.
8. the second stage of cellular respiration is the ______________ cycle.
9. the third stage of cellular respiration is the ______________ transport chain.
10. the majority of atp is produced in the third stage, through______________ phosphorylation.
11. atp ______________ is a protein that uses the proton gradient in the etc to make atp.

Explanation:

1. Cellular respiration converts glucose into energy. Glucose is the main fuel for this process.
2. Mitochondria are the organelles where most of cellular - respiration occurs.
3. The chemical equation for cellular respiration is Glucose + Oxygen → Carbon Dioxide + Water + ATP. This is a redox reaction.
4. The function of cellular respiration is to produce ATP, which is used as energy currency in cells.
5. Anaerobic respiration does not require oxygen. It is an alternative pathway when oxygen is scarce.
6. During glycolysis, glucose is broken down into two molecules of pyruvate.
7. Fermentation is a type of anaerobic respiration that occurs when there is not enough oxygen. It includes lactic - acid fermentation and alcoholic fermentation.
8. Yeasts produce ethanol during fermentation.
9. Humans undergo lactic - acid fermentation when muscles lack oxygen.
10. The first stage of cellular respiration is glycolysis, which occurs in the cytoplasm.
11. The second stage is the Krebs cycle, which takes place in the mitochondrial matrix.
12. The third stage is the electron transport chain, located in the inner mitochondrial membrane.
13. The majority of ATP is produced in the third stage through oxidative phosphorylation.
14. ATP synthase is a protein that uses the proton gradient in the ETC to make ATP.
