Question: Reflect and apply Experimental evidence strongly suggests that the protein
Reflect and apply Experimental evidence strongly suggests that the protein portions of cytochromes have evolved more slowly (as judged by the number of changes in amino acids per million years) than the protein portions of hemoglobin and myoglobin and even more slowly than hydrolytic enzymes. Suggest a reason why.
Answer to relevant QuestionsReflect and apply List the reactions of electron transport that liberate enough energy to drive the phosphorylation of ADP. Reflect and apply Show how the reactions of the electron trans port chain differ from those in Question 3 when FADH2 is the start ing point for electron transport. Show how the reactions that liber ate enough energy to drive ...(a) The major energy storage compound of animals is fats (except in muscles). Why would this be advantageous? (b) Why don’t plants use fats/oils as their major energy storage compound? Compare and contrast the pathways of fatty-acid breakdown and biosynthesis. What features do these two pathways have in common? How do they differ? Uncouplers of oxidative phosphorylation in mitochondria also uncouple photoelectron transport and ATP synthesis in chloroplasts. Give an explanation for this observation.
