Which statement BEST describes the concept of "amplification" in biosignaling?
A) Higher concentrations of signal molecules lead to stronger cellular responses.
B) In response to the presence of a signal molecule, more signal molecules are synthesized.
C) Small amounts of extracellular signal will trigger multiple intracellular effects via enzyme cascades.
D) All of the statements describe this concept.
E) None of the statements describes this concept.

Question

Quizplus · Accepted Answer

Amplification in biosignaling refers to the process by which a small amount of extracellular signal triggers multiple intracellular effects, often via enzyme cascades. This allows for a greater cellular response to a limited signal, resulting in a more significant physiological effect. Option A is partially correct in that higher concentrations of signal molecules can lead to stronger cellular responses, but this is not necessarily the direct result of amplification. Option B is incorrect as it describes a feedback loop rather than amplification. Option D is incorrect as it combines all the statements, and only C fully describes the concept of amplification in biosignaling. Option E is incorrect as there is a correct answer.
