The chemical nature of LH and ICSH is:
Correct answer: C. Polypeptides
- A. Steroids
- B. Tyrosine derivatives
- C. Polypeptides
- D. Amino acids
Explanation
LH and ICSH are glycoprotein hormones, which means they are composed of both protein and carbohydrate components. The protein backbone is formed by a chain of amino acids, and carbohydrate chains are attached to this protein core. These hormones are relatively large and structurally complex, qualifying them as polypeptides

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
