Question

multiple choice question
a peptide hormone binds to its receptor on the cell surface. this binding activates a few second messengers, each of which goes on to activate multiple intracellular enzymes. this is known as a(an):
o response cascade
o enzyme cascade
o hormone cascade

Explanation:

A response cascade occurs when a signal - like a peptide hormone binding to a cell - surface receptor - triggers a series of events where second messengers activate multiple intracellular enzymes. An enzyme cascade specifically refers to a series of enzyme - catalyzed reactions. A hormone cascade involves hormones acting in a sequential manner. Here, the overall process of signal transmission and amplification starting from hormone - receptor binding and involving second messengers and enzyme activation is a response cascade.

Answer:

response cascade
