Amines, peptides, and proteins are examples of ______ hormones that bind to receptors in the target cell membranes.Multiple choice question.nonsteroidsteroid

Break Down the Problem

1. We need to identify the category of hormones that includes amines, peptides, and proteins.
2. The options provided are "nonsteroids" and "steroids."

Relevant Concepts

1. Hormones can be broadly classified into two categories: steroid hormones and nonsteroid hormones.
2. Steroid Hormones: These are derived from cholesterol and are lipid-soluble, which allows them to pass through cell membranes and bind to receptors inside target cells.
3. Nonsteroid Hormones: These include amines, peptides, and proteins. They are typically water-soluble and cannot pass through the cell membranes. Instead, they bind to receptors on the surface of target cells.

Analysis and Detail

1. Amines, peptides, and proteins are derived from amino acids and fall under the category of nonsteroid hormones.
2. Nonsteroid hormones act by binding to receptors located on the cell membrane, activating secondary messengers to exert their effects.

Verify and Summarize

• Since amines, peptides, and proteins do not have the lipid-solubility characteristic of steroids and instead bind to cell membrane receptors, we can confirm that the correct answer is "nonsteroids."

Final Answer

Nonsteroid hormones.
