Can you please help me with some science questions?

Question

1. Does NADH directly or indirectly provide energy for the cell to do work? Explain.

2. Besides releasing energy, what else does decomposition provide?

3. Where are all of the NADH and FADH2 molecules being made in the 1st 3 stages of cellular respiration taking the H+ and e-?

4. What are 3 organic compounds that can be used in cellular respiration?

5. What happens to pyruvate in animal cells if there is not enough oxygen present?

6. What is the anaerobic pathway of animals called?

7. What do plants and bacterial cells produce in the absense of oxygen?

8. Glycolysis is also the first stage in what anaerobic process?

9. To what 3 molecules can pyruvate be converted if no O2 is present?

10. If oxygen is present in animal cells, where does the pyruvate go?

Answer 1

go do your homework.

Answer 2

1.NADH is an enzyme,so it doesn't provide energy fro the cell do to work. however, it lowers the activation energy, which is the energy required for reaction to occur, therefore the reaction occurs quicker.

2. Food such as ions for plants to grow ( I guess lol)

3. I think the reaction occurs within the inner membrane of mitochondria

4. glucose, glycogen and starch.

5. I think cell will die as high level of carbondioxide will toxic the cell and also the lack of energy for cell to do cell activities

6. anaerobic metabolism

7. lactice acid and 2 molecules of ATP ( anaerobic respiration)

8: Anerobic respiration

9. ATP, ethanol or lactic acid
