Q1) The first step of glycolysis is the synthesis of glucose 6-phosphate by hexokinase. What is the biochemical strategy for this first step?
Q2) During exercise, muscle cells are anaerobic and the pyruvate produced from glycolysis does not enter the Citric Acid Cycle. Why is fermentation to lactate required for glycolysis to continue?
Q3) Why are there cytoplasmic and mitochondrial pools of acetyl-CoA?
Q4) Explain Mitchell's chemiosmotic theory and how it accounts for ATP synthesis in mitochondria, and for driving flagella in bacteria for motility.
Q5) In cells, metabolic pathways can be regulated at many different levels. List and briefly discuss how metabolic pathways could be regulated.
