- Given the discussions on the link between metabolism and energy demand, which of the following statements would be accurate? a. Compared to glycogenolysis, lipolysis is the more heavily relied upon for supporting the energy needs at rest b. Upon transition from rest to exercise, the amount of carbohydrate metabolism decreases c. Due to its low energy:substrate molar ratio, CrP metabolism does not contribute to the energy needs during rest. d. All of the above are accurate statementsarrow_forwardWhich of the following statements regarding glycogen are true? A. Glucose from glycogen can be metabolized anaerobically B. Approximately 1-2% of muscle weight is glycogen, whereas 10-15% of liver weight is glycogen C. It is faster for the muscle to obtain energy from glycogen than from lipids D. A and B are true E. B and C are true F. Both A, B, and C are truearrow_forwardBasal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%). Calculate your basal metabolic rate in Calories using the appropriate equation here: Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs)) Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs)) Calculate how many Calories you burn overall in a day.arrow_forward

Step changes in a controlled variable will return the system to its original state using negative feedback b. Metabolic systems that oscillate must have multiple control variables c.A positive feedback system is stable over time, maintaining a steady state d. Perturbations from steady state, either positive or negative, result in recovery reactions that returm the system to is original state.arrow_forwardWhich of the following statements about glucose metabolism is correct? A. Glucagon increases the rate of glycolysis B. Glycolysis requires NADP+ C. In glycolysis, glucose is cleaved into two three-carbon product D. The end-product of glycolysis in red blood cells is pyruvate E. Glycogen is synthesized in the liver in response to insulin and exported to other tissues for use as a metabolic fuelarrow_forward

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_forwardwhich of the following does not have a stored form of energy reserve, but is readily able to switch from utilizing glucose to utilizing ketone bodies?
