Metabolism is built on two distinctly different types of pathways: catabolic and anabolic. Which of the following statements correctly identifies an aspect of these pathways?   1. Anabolic pathways often require energy coupling reactions with ATP. 2. All the reactions of an anabolic pathway are endergonic. 3. Overall, a catabolic pathway has a negative change in free energy. 4. Photosynthesis is an example of a catabolic pathway.    A.  1, 2 and 3  B.  1 and 3  C.  2 and 4  D.  4 only  E. All of 1, 2, 3 and 4 are correct

NADH and succinate are substrates that can be oxidized and will consume oxygen. Rotenone and cyanide are inhibitors of the electron transport chain and can block oxidation. Match each description of the effector to the appropriate oxygen consumption. A plot may match more than one description. Some plots will not match any description. (At least one of the matches in the image was incorrect)
