Question

Number of affected molecules increases geometrically in an enzyme cascade in _____________

(a) Specificity

(b) Amplification

(c) Adaptation

(d) Integration

This question was posed to me during an internship interview.

This is a very interesting question from Molecular Mechanisms of Signal Transduction topic in portion Biosignalling of Biochemistry

Answer 1

The correct option is (b) Amplification

To explain: Signal molecule fits its binding site on its complementary receptor called as specificity.

Receptor is removed from cell surface in adaptation.

A regulatory outcome result from integrated input from both receptors is in integration.
