- Which out of the following statements is true about the regulation of metabolic pathway? a) Most of the metabolic pathways are regulated b) Most of the metabolic pathways are not regulated c) Regulation of metabolic pathways always involves changing the amount of enzymes d) Metabolic regulation always depends on control by hormonesarrow_forwardThe figure above represents changes in different types of metabolic pathways (y-axis) as energy charge in a cell (x-axis) changes. What is the best description of the types of reactions shown by the green line labeled "A"? a) Catabolic, energy-consuming pathways b) Anabolic, energy-consuming pathways c) Anabolic, energy-producing pathways d) Catabolic, energy-producing pathwaysarrow_forwardHow different metabolic pathways are related to each other?arrow_forward
- Which of the following are common to all metabolic pathways? a) Citric acid cycle b) Oxidative phosphorylation c) Electron transport chain d) All of the abovearrow_forwardWhich metabolic reaction is convergent? Why?arrow_forwardWhy are most enzymes larger than the substrates on which they act?arrow_forward
- Metabolic pathways can function efficiently without external control, and will not overproduce unnecessary product molecules because: a) Large pH shifts speed up reactions b) Cells release lots of heat to accelerate product formation c) End products of a pathway cause early enzymes to change shape and inactivate d) Active sites become saturated as product concentration risesarrow_forwardWhich metabolicoption yields more energy, and why?arrow_forwardcreate a single illustration that will interrelate or link the two opposing pathways, the Glycogenesis and Glycogenolysis. I want you to include the enzyme in each step and include some important by-products as well. From the illustration, I want you to encircle the intermediate molecule to highlight the link between the two processes. Aside from the illustration, I want you to compare and contrast the two pathways in terms of function, number of reaction steps, and usage of UTP. You can tabulate this part to make it simpler.arrow_forward
