To maintain homeostasis, the hormone that is secreted during the postabsorptive state causes Question options: a decrease in the level of fatty acids in the blood. an increase in protein synthesis in tissue cells. formation of tryglicerides from fatty acids. an increase in the level of blood sugar.

an increase in the level of blood sugar.

What effect does glucagon have on protein metabolism? Question options: It directly stimulates catabolism of proteins. It stimulates the buildup of proteins from amino acids. It increases absorption of amino acids in the intestine. It has no effect on body proteins.

It directly stimulates catabolism of proteins.

Beta oxidation is a step in the synthesis of cholesterol that involves Question options: closing of a linear fatty acid chain into a steroid loop. breakdown of fatty acids into two-carbon units to form acetyl CoA. synthesis of bile salts from precursor lipids. absorption of micelles from the small intestine.

breakdown of fatty acids into two-carbon units to form acetyl CoA.

How do low-density lipoproteins (LDLs) move into cells? Question options: LDLs diffuse through channels in the membrane. LDLs are engulfed through receptor-mediated endocytosis. LDLs diffuse through the phospholipid bilayer. LDLs are transported through a pump that is also an ATPase.

LDLs are engulfed through receptor-mediated endocytosis.

High-density lipoproteins (HDLs) are associated with the tranport of lipid from the Question options: liver to periperal tissues. peripheral tissues to the liver.

peripheral tissues to the liver.

One of the metabolic functions of the liver is transamination, which is conversion of Question options: NH 2 to urea. one amino acid form to another. amino acid into carbohydrate. acetyl CoA to a ketone body.

one amino acid form to another.

When glucose enters glycolysis, it Question options: is converted into acetyl CoA. binds to oxaloacetic acid and forms citric acid. is oxidized to two pyruvate molecules. forms the coenzyme NAD.

is oxidized to two pyruvate molecules.

An amine group that is removed from an amino acid within a hepatocyte is then Question options: used to form a peptide bond between a protein and a lipid. used to generate bile salts and excreted in the feces. converted to urea and eliminated as part of urine. sent to a mitochondria to enter the citric acid cycle.

converted to urea and eliminated as part of urine.

Explain how the ability to interconvert nutrients is beneficial.

The ability to interconvert nutrients is beneficial because it allows the body to maintain homeostasis and meet its energy and structural needs even when the intake of specific nutrients is imbalanced.

If more glucose is consumed than is needed, the glucose can be Question options: converted to an essential amino acid so that protein synthesis can increase. converted to acetyl CoA that is then used to synthesize triglycerides for storage. broken down to 2 NADH molecules that can enter the citric acid cycle. deaminated by the liver and sent to the kidney for excretion in the urine.

converted to acetyl CoA that is then used to synthesize triglycerides for storage.

Metabolic rate is a measurement of the Question options: total number of calories consumed per hour. amount of oxygen consumed per kilogram of body weight. energy used in a given period of time. heat given off by contracting muscles.

energy used in a given period of time.

Metabolic rate can be measured with a respirometer that measures Question options: water content of the breath in order to directly measure the products of cellular respiration. water content of the breath in order to indirectly measure the products of cellular respiration. temperature of the expired air in order to measure the rate of the sum of all reactions within the body. oxygen consumption in order to indirectly measure heat production and energy expenditure. temperatures of carbon dioxide and oxygen to determine how much the body warmed the respiratory gas.

oxygen consumption in order to indirectly measure heat production and energy expenditure.

Vigorous physical activity causes total metabolic rate to Question options: increase for the duration of the exercise. increase during the exercise and for hours afterwards. remain constant. decrease to conserve energy during the exercise but increase to repay oxygen debt. decrease during the exercise and for hours afterwards.

increase during the exercise and for hours afterwards.

Core body temperature is the Question options: average temperature across all portions of the body. average body temperature across all hours of the day. temperature of the head and torso. temperature recorded at the center of the long bones of the limbs.

temperature of the head and torso.

Sweating and shivering are necessary adaptations because Question options: all parts of the body must remain at normal body temperature to maintain life. the health of vital organs requires a near-normal temperature, and metabolic rate fluctuates with changes in the environment. to ensure that total metabolic rate remains constant, the body generates or releases heat as needed. proteins rapidly denature when tissue temperature drops below 98.5°F.

the health of vital organs requires a near-normal temperature, and metabolic rate fluctuates with changes in the environment.

An increase in metabolic rate would alter body temperature and trigger a compensatory Question options: stimulation of sweat glands and vasoconstriction in blood vessels of the skin. stimulation of sweat glands and vasodilation in blood vessels of the skin. inhibition of sweat glands and vasoconstriction in blood vessels of the skin. inhibition of sweat glands and vasodilation in blood vessels of the skin.

stimulation of sweat glands and vasodilation in blood vessels of the skin.

In response to decreases in body temperature, the brain signals the Question options: anterior pituitary to release thyroid-stimulating hormone. anterior pituitary to release thyroid-inhibiting hormone. posterior pituitary to release thyroid-releasing hormone. posterior pituitary to release thyroid-inhibiting hormone.

anterior pituitary to release thyroid-stimulating hormone.
