- The pentose phosphate pathway is composed of two distinct phases. What are the two phases and what are their roles?arrow_forwardWhat is the major purpose of the pentose phosphate pathway? What cofactor (coenzyme) is used?arrow_forwardA mutation has occurred that results in phosphofructokinase not being able to bind ATP in its allosteric site. What impact will this mutation have on the production of ATP in the cell? Select one: a. If no ATP can bind to the allosteric site, then phosphofructokinase will not be able to add the phosphate to fructose-6-phosphate to make fructose-1,6-bisphosphate and glycolysis will not work. So no pyruvate, not cellular respiration. b. If ATP cannot bind to the allosteric site, phosphofructokinase will not be activated to make more ATP by substrate-level phosphorylation. c. No impact on the production but will not be able to effectively shut off over production of ATP with feedback inhibition.arrow_forward
