Document Summary
Psl201 mar 4 endocrine 6: energy metabolism. Energy metabolism: the way your body stores and utilizes energy. Because food intake is intermittent the body must tor nutrients during periods of intake and then break them down between meals. Blood glucose levels must be maintained because the brain depends on glucose. Usually found as glucose in the bloodstream. Aa rather than proteins are transported in the blood. In cells: aa are used for synthesis of proteins, aa are catabolized for energy by proteolysis, proteins function as aa stores and can be broken back down to aa. Psl201 mar 4 endocrine 6: energy metabolism stored triglycerides can be broken down to glycerol and fatty acids: then catabolized for energy or released into bloodstream for use by other cells. Energy metabolism during the absorbtive and postabsorptive states. During the absorptive state, energy is stored in macromolecules; during the postabsorptive state, these energy stores are mobilized.
