Homework Answers
Answer: Pyruvate dehydrogenase (PDH) is an enzyme that catalyze important step in cellular respiration. It is part of pyruvate dehydrogenase complex that convert pyruvate to acetyl CoA. PDH is regulated by PDH kinase and phosphatase. PDH kinase phosphorylates the PDH and inactivate the enzyme. Phosphatase removes the phosphate from inactive PDH and converts it to active form. Insulin and Ca2+ stimulate the phosphatase. In resting condition, insulin stimulates the phosphatase that activates PDH. In non-resting condition such during exercise and physical activity, Ca2+ activates the phosphatase. Hence, option a is the correct answer and option e is incorrect. Epinephrine, PFK-2 and citrate does not stimulate phosphatase. Hence, options b, c and d are incorrect.

please answer all 1. A type of adipose tissue in many organisms is called brown fat. Which of the following statements is correct for brown fat? Hibernating bears have very little of this type of adipose tissue. It produces a great deal of heat as a result of the presence of thermogenin. The efficiency of oxidative phosphorylation is high in this tissue. Its color is derived from high blood supply. 2. What statement illustrates the role of Ca2+ in regulation...
