Summary Introduction
To determine:
The processes occurring within the body if a person eats 600 kilocalories of protein in a meal.
Introduction:
Proteins are building blocks of cells. They are made up of 20 different types of amino acids. Proteins perform various functions in physiological activities. Some are enzymes due to their catalytic ability, others are hormones secreted from different glands, and so on.

b.
High insulin/glucagon ratio inhibits lipogenesis in liver.
c.
Low insulin/glucagon ratio activates lipolysis in adipocytes.

Which of the following statements about insulin is true?
a. Insulin acts as a transport protein, cany in g glucose across the cell
membrane.
b. Insulin facilitates the movement of inti acellular glucose transporters to the cell membrane. c. Insulin stimulates the breakdown of stored glycogen into glucose.
d. Insulin stimulates the kidneys to reabsorb glucose into the
bloodstream.
Untreated diabetes leads the body to mobilize glucose stores and break down fats. If the issue is that blood glucose is too high, why does this happen?
a. Intracellular stores of glucose are very low and the cells feel starved
b. All of the above explain why this happens
c. Most of the glucose leaves through the kidneys since glucose has exceeded Tmax
d. Circulating fat stores are low, which promotes lipolysis
e. A lack of insulin results in chronic sympathetic drive, using up all the blood glucose

- The hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.arrow_forwardBasal metabolic rate is a measure of ______. a. the total amount of calories you burn in 24 hours b. the amount of food energy needed to sustain basic body operations c. the amount of energy burned by skeletal muscle in a given period d. both a and barrow_forwardIncreasing blood glucose concentration during the absorptive period in healthy individuals a.Stimulates Pancreas to secrete Glucagon b.Inhibits glucose uptake by liver and peripheral tissues c.Stimulates Pancreas to secrete Insulin d.All of the abovearrow_forward

- With regard to thermoregulation in humans, what could be considered an accurate consequence of the outside temperature dropping below the lower critical temperature? A. The individual will begin to breathe in less oxygen and exhale less carbon dioxide. B. The metabolic needs of the individual will increase if they remain below the lower critical temperature for sufficient time-frames. C. Capillaries (i.e. blood vessels) near the surface of the skin will dilate in order to allow blood to circulate more freely throughout the organism, distributing heat to raise temperature. D. The person's Basal Metabolic Rate will be lowered to match the Standard Metabolic Rate of an ectotherm of comparable size. E. Hormones from the hypothalamus will be released, which lead to the initiation of a positive feedback response that amplifies muscle contraction, leading to shivering.arrow_forwardll of the following statements about basal metabolic rate (BMR) are true, Except: a.
