Question

1.

The concentration of ADP in a cell is increasing. Assuming that the cell has plenty of glucose and oxygen available, fatty acid synthesis should:

will it stay the same, increase or decrease

2.

will it stay the same,increase, or decrease

The concentration of ADP in a cell is increasing. Assuming that the cell has plenty of glucose and oxygen available, fatty acid synthesis should:

will it stay the same, increase or decrease

2.

The concentration of ADP in a cell is increasing. Assuming that the cell has plenty of glucose and oxygen available, phosphofructokinase (PFK) activity should:

will it stay the same,increase, or decrease

Explanation / Answer

1.
High levels of ATP promotes fatty acid synthesis.
High levels of ADP promotes beta-oxidation of fatty acids.

2.
A high ATP/ADP ratio inhibits PFK and glycolysis.
So, High levels of ADP promotes PFK and glycolysis.
