Hello I Have A Question About Exercise Physiology List Seven Specifically Differ

Hello! I have a question about exercise physiology:

List seven specifically different methods by which metabolic systems/pathways can be controlled.

Cite detailed examples (one acute and one chronic for each of the seven you listed) that demonstrate how the body utilizes each of the seven methods listed above.

Here is my question:

Imagine that I use Lactate as a substrate for the first method. How would this substrate be affected acutely and chronically ??

could you also give an example for an enzyme?

I hope everything is clear!

Thank you
