A person has not eaten for about 12 hours. Which substance(s) does the body use to increase blood sugar, until the person can eat? (Select all that apply)

A. Glycogen: The liver breaks down stored glycogen into glucose (glycogenolysis) to maintain blood sugar levels.

B. Metabolism: Metabolism refers to all chemical processes in the body but is not a specific substance that increases blood sugar.

C. Glucagon: Glucagon is a hormone released by the pancreas to stimulate glycogen breakdown and gluconeogenesis, increasing blood sugar levels.

D. Insulin: Insulin lowers blood sugar by promoting glucose uptake into cells, so it would not be used to increase blood sugar.

E. Glycolysis: Glycolysis is the breakdown of glucose for energy; it does not raise blood sugar levels.

A. Are found primarily in the axillary and genital areas: Apocrine glands are sweat glands located in the armpits (axillary) and genital regions. They become active at puberty and secrete a thicker sweat that can cause body odor.

B. Are endocrine glands: Apocrine glands are exocrine glands, not endocrine. They release their secretions onto the skin surface through ducts rather than into the bloodstream.

C. Arise within the hypodermis: Apocrine glands are located in the dermis, not the hypodermis. The hypodermis consists mostly of fat.

D. Are called oil glands: Oil glands (sebaceous glands) produce sebum, while apocrine glands secrete sweat.
