Can someone please enlighten me on this one, I don't understand Why B is correct and the answer is not clear to me.
Thanks

To solve think about what each ATP and AMP do.

ATP in excess is a form of negative regulation. This will slow down the rate of glycolysis
AMP in excess is a form of positive regulation. This will increase the rate of glycolysis.

We want to slow down glycolysis so we want a lot of ATP and a little AMP.

This will give us a large ratio of ATP:AMP

Also, think about this from a broad concept view. What does glycolysis produce? ENERGY--in the form of ATP. Thus, it would make sense that we would want to undergo glycolysis when there is little energy (low ATP, high AMP), and we would want to slow glycolysis when there is a lot of energy (high ATP, low AMP). Thus the answer to this question is a high ATP : AMP ratio.
