Question

#2

Succinate dehydrogenase is the enzyme that catalyzes the conversion of succinate to fumarate, releasing electrons that are used to reduce FAD to FADH2. If a mutation changed the active site of this enzyme, what do you predict might be the effect on the remaining steps in the citric acid cycle? Would there be any effect on the amount of ATP produced in cellular respiration from 1 molecule of glucose? Increasing concerns about dependence on fossil fuels has generated research and development of renewable fuels, such as ethanol. Ethanol can be produced from grains (for example, corn) or from plant biomass

Explanation / Answer

If a mutation changed the active site of the enzyme then the remaining steps of the citric acid cycle will be affected in terms of production of ATP will be less and more time will be required to complete the cycle
