Your answer must consist of at least four discrete paragraphs including:an introductory paragraph;two or more “body” paragraphs; anda concluding paragraph. Each paragraph must contain at least two sentences.Topic List:Explain why, in physiological systems, buffers are usually weak acids with a pK value that matches, or nearly matches, the surrounding pH under normal conditions.Explain why the anaerobic metabolism of glucose requires the conversion of pyruvate to lactate.Discuss the relative advantages and disadvantages of creatine phosphate hydrolysis, anaerobic glycolysis and oxidative glucose metabolism as intracellular mechanisms for the production of stored chemical energy (ATP, GTP) and heat.Describe the way in which the protein complexes of the inner mitochondrial membrane restore the proton acceptors, NAD+ and FAD and explain how this process is used, in the aerobic metabolism of glucose, to create a PMF capable of generating substantial quantities of heat and stored chemical energy.Describe, using an example, signal transduction and amplification in a G-protein coupled receptorCompare the processes that lead to the release of hormones from the anterior and posterior pituitary hormones. Build on this to explain why, when the stalk connecting the hypothalamus to the pituitary hormone is compressed, the compression can result in the hyposecretion of ACTH, TSH, LH & FSH and the hypersecretion of PRL (prolactin), while having little to no effect on the secretion of the posterior pituitary hormones.Describe in detail the hormonal regulation of reproduction in male mammals. Explain why this process sometimes leads to testicular hypertrophy in mammals that breed seasonally.
