- Which metabolic reaction is convergent? Why?arrow_forwardWhat are metabolic pathways catalyzed by? What are metabolic pathways determined by?arrow_forwardWhich of the following is NOT true about metabolic pathways in general? They can be anabolic or catabolic They can be both energy-releasing (exergonic) and energy-requiring (endergonic) They are often made up of a series of chemical reactions They often have multiple different enzymes working in the same pathway Each metabolic pathway is entirely separate and does not interact or connect at all with other metabolic pathwaysarrow_forward
- – Why are metabolic pathways so similar in many organisms?arrow_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_forwardWhich metabolicoption yields more energy, and why?arrow_forward
