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...

1. 2,4-Dinitrophenol (DNP) is a molecule that can shuttle protons across cellular membranes and was used in diet pills in the 1930s (but was quickly discontinued for its lethality). Explain how this molecule might induce weight loss, and why its consumption is often fatal. 2. Biosynthesis and breakdown of glucose share many common enzymes and reactions, but this is not the case in the metabolism of fatty acids. Compare and contrast fatty acid biosynthesis vs. beta-oxidation (location, acyl group carriers,...
