Can a cell undergo respiration when glucose is not available?

Answer 1

Yes, it can in a process called anaerobic respiration.

Answer 2

Yes, a cell can still undergo respiration when glucose is not available. In the absence of glucose, cells can use other molecules such as fats and proteins as alternative energy sources to carry out respiration. This allows cells to continue producing ATP for their energy needs.

Answer 3

The breaking down of glucose in the presence of oxygen is called the "light reaction." or aerobic cellular respiration. Either is correct.

Answer 4

Anaerobic respiration occurs in the absence of oxygen. This is opposed to aerobic respiration, which occurs in the presence of oxygen. In humans anaerobic respiration produces lactic acid.

Answer 5

Yes. Although glucose is used most commonly in explaining the process of respiration, other nutrients (lipids & proteins) are transformed by respiration as well.

Answer 6

Not without having fermentation.
