A) Rapid enzyme activation
B) Rapid enzyme inhibition
C) Opening of ion channels in the plasma membrane
D) Icreased expression of certain genes
E) Changes in the calcium concentration in the cytosol

Question

Quizplus · Accepted Answer

Activation of transcription involves the production of mRNA from DNA, resulting in increased expression of certain genes. This process is a slower response to signal transduction compared to rapid enzyme activation or inhibition, and is often involved in longer-term changes in cellular behavior. Opening of ion channels in the plasma membrane and changes in calcium concentration in the cytosol can lead to rapid changes in the cell, but do not involve activation of transcription.
