MICROANATOMY

Detailed explanation-1: -The binding of the hormone triggers an enzyme inside the cell membrane. The enzyme activates another molecule, called the second messenger, which influences processes inside the cell. Most endocrine hormones are non-steroid hormones, including insulin and thyroid hormones.

Detailed explanation-2: -Answer and Explanation: The secondary messenger most often involved in non steroid hormone action is cyclic AMP (cAMP).

Detailed explanation-3: -Nonsteroid hormones bind to receptors in a target cell and cause the release of secondary messengers that affect cell activities.

Detailed explanation-4: -Some of the hormones that achieve their effects through cAMP as a second messenger: adrenaline. glucagon. luteinizing hormone (LH)

Detailed explanation-5: -Nonsteroid hormones generally cannot pass through the cell membrane of their target cells. Nonsteroid hormones bind to receptors in a target cell and cause the release of secondary messengers that affect cell activities.
