- The human body is composed of water, proteins, fat, and minerals. Its specific heat reflects thiscomposition. With 75% water and 25% protein, what would be the specific heat of the body?Differentiate the three ways of heat transfer.The uncoupling of photon movements results in thermoregulation. Explain and define the terms Brown fat and non shivering thermogenesis as to the production of heat in babies.Which animal would you expect to have more brown fat (provides heat by uncoupling ATP production), a seal or a domestic cat? Explain.
- What effect is observed on the rate of glycolysis under each of the following conditions? a. low ATP concentrationc. high carbohydrate diet b. low ADP concentrationd. low carbohydrate dietDefine the term shivering thermogenesis?Using a specific evidence of thermoregulation to support the statement that “The importance of the effect of temperature on physiological function is revealed by adaptations to maintain function at different temperatures”. How exactly is thermoregulation involved as an adaptation?
- Calculate the amount of evaporation that must occur to remove 400 kcal of heat from the body.What happens to the metabolic rate during exercise? Explain why you feel warm when you exercise, even if the environmental temperature is cold?Which is true for Non-Shivering Thermogenesis? Group of answer choices It is associated with uncoupling of oxidative phosphorylation It is associated with muscle contractions It is associated with ATP production it is associated with reduction in glucose use
- Claude Bernard, a nineteenth-century French physiologist often considered the father of modern animal physiology, is still remembered today for his famous dictum: “Constancy of the internal environment is the condition for free life.” Does the study of thermal relations lend support to his dictum? Explain.Endotherms can regulate how much heat is gained or lost between the environment and their bodies via 4 different mechanisms/processes. List and describe these mechanisms.Define nonshivering thermogenesis?
