Which of the following is characteristic of water-soluble hormones?
A
They bind to receptors on the cell surface.
B
They are typically derived from cholesterol.
C
They pass through the cell membrane to bind intracellular receptors.
D
They have a long half-life in the bloodstream.
Verified step by step guidance1
Understand the nature of water-soluble hormones: Water-soluble hormones are typically peptides or proteins, which means they are not able to pass through the lipid bilayer of the cell membrane.
Identify how water-soluble hormones interact with cells: Since they cannot pass through the cell membrane, water-soluble hormones bind to receptors located on the surface of the target cell.
Differentiate between water-soluble and lipid-soluble hormones: Lipid-soluble hormones, such as steroid hormones derived from cholesterol, can pass through the cell membrane and bind to intracellular receptors.
Consider the half-life of water-soluble hormones: Water-soluble hormones generally have a shorter half-life in the bloodstream compared to lipid-soluble hormones, which are often bound to carrier proteins.
Conclude the characteristic of water-soluble hormones: Based on the above analysis, the characteristic of water-soluble hormones is that they bind to receptors on the cell surface.
