Based on the information in Figure 2, predict the effect of this mutation on the activity of glycogen synthase. (b) Justify your prediction in part (a). Describe the process that results in the activation of multiple copies of PKB in response to the binding of a single molecule of insulin to its receptor. (d) Explain why...

During glycogenolysis, muscle cells consume most of the glucose released from the stored glycogen; while liver cells export most of the glucose released from the stored glycogen. Why do the muscles and liver behave so differently and how do you explain this phenomenon?

Do expect the cell to produce more ATP from one glucose molecule or from one fatty acid molecule? Explain your answer. Indicate whether the following statements are true or false. If a statement is false, explain why it is false The proteins of the electron-transport chain remove a pair of high-energy electrons from the cofactors, NADH and FADH_2, after which the electrons move across the inner mitochondrial membrane to maintain the voltage gradient. Gluconeogenesis is a linear reaction pathway that...

4. 15 marks) Let C denote the concentration of paracetamol in your blood. When you take the parac- etamol C goes up quickly and then declines slowly over the next few hours, as your liver clears the drug from your body (or as the drug gets metabolised or excreted) Here are some typical data.1 The "test drug" and "reference drug" refer to two slightly different forms of paracetamol; the data show how the test version of the drug is absorbed...
