Which of the Following is Characteristic of Aldosterone Action

Question

Which of the following is characteristic of aldosterone action?
A)protein phosphorylation
B)cell-surface receptor binding
C)internal receptor binding
D)second messenger activation
E)ion flow across the plasma membrane

Accepted Answer

Aldosterone is a steroid hormone that acts by binding to internal receptors, specifically mineralocorticoid receptors, which are located inside the cell. This binding leads to changes in gene expression and protein synthesis, affecting ion transport and balance.
