Answer:

b. to amplify the signal

Explanation:

A multi-enzyme phosphorylation cascade is a series of signaling events where one enzyme phosphorylates to another, then this last enzyme acts to phosphorylate another protein and so successively, thereby triggering a chain reaction that leads to the phosphorylation of hundreds or even thousands of proteins. A multi-enzyme phosphorylation cascade is known to increase the number of activated (phosphorylated) proteins at each step of the signaling cascade. Phosphorylation is a posttranslational modification capable of activating proteins during long periods, thereby a phosphorylation cascade also enables the activation of multiple proteins before these proteins become inactive again.

When two hormones must be present to achieve full expression of an effect, that interaction is called ______________.
Vinvika [58]

Answer:

Synergism

Explanation:

Synergism means cooperation, and is a term of Greek origin (synergy). Synergy is a work or effort to accomplish a certain very complex task, and to be able to succeed in the end. Synergy is the moment when the whole is greater than the sum of its parts.

In physiology, synergism occurs when the effect of two or more combined chemical agents is greater than the sum of individual effects. Concerning hormones, synergism happens when two hormones must be present for the full expression of an effect. That is, two hormones act for a certain purpose.

Example: FSH (follicle stimulating hormone) and estrogen cause oocyte maturation, but this only occurs if neither acts in isolation.
