What is the main function of the endocrine system?

• It creates chemicals, or hormones, that are sent around the body to maintain homeostasis.

• It creates electrical messages that are sent around the body to maintain homeostasis.

• It releases waste from the body to maintain homeostasis

Which description best fits non-steroid hormone acting on a target cell?

• hormone binds to receptors on the cell membranes, activating an enzyme on the inner surface of the cell membranes. This enzyme activates a second messenger.

• hormones, which are made of lipids, move across the cell membranes of target cells.

• Once inside, a steroid hormone binds to a steroid receptor protein, forming a hormone-receptor complex

• none of these are correct

Which description best fits steroid hormone acting on a target cell?

• hormone binds to receptors on the cell membranes, activating an enzyme on the inner surface of the cell membranes. This enzyme activates a second messenger.

• hormones, which are made of lipids, move across the cell membranes of target cells.

• The second messenger then activates or inhibits cell activities

• adrenaline very much plays a role

Insulin is produced by the _________ in the ____________.

• alpha cells, pancreas

• beta cells, pancreas

• alpha cells, liver

• beta cells, liver
