Exam 30: A: Nutrition and Metabolism

Polysaccharides,disaccharides,and monosaccharides have to be digested before they can be absorbed into the internal environment.

Whereas insulin tends to decrease the blood glucose level,glucagon tends to increase it.

One function of lactic acid is to convert NADH back to NAD.

In the electron transport system,the energy in one FAD molecule is used to form two ATP molecules.

Both NAD and FAD can be used by the cell to transfer energy.

The cells add phosphate to glucose so it can pass through the cell membrane more easily.

Calcium can be called both a macronutrient and a macromineral.

Nutrition can be explained most simply by describing it as the way your body uses food.

Deamination,a process that occurs in the liver,is the first step in the catabolism of proteins.

Both pregnancy and lactation can increase the basal metabolic rate.

Only muscles store glycogen.

Nutrient anabolism is required to rebuild ADP into ATP.

Oxidative phosphorylation refers to the joining of a phosphate group to ADP to form ATP.

Both pyruvic acid and lactic acid can be produced from the breakdown of glucose.

When the blood glucose levels rise to 80 to 90 mg/dl,it stimulates the formation of glycogen in cells.

The Cori cycle rebuilds glucose from pyruvic acid to pay off the oxygen debt.

The smell of acetone on the breath is a sign of ketosis.

All cells have the ability to digest glycogen and release glucose into the blood.

Vitamin C has an antioxidant effect.

Growth hormone is considered an anabolic hormone.
