Answer :
If a poison is added to block complex III, the number of ATP produced instead will be reduced to 38.
Complex III, also known as the cytochrome bc1 complex, plays a vital role in the electron transport chain, which is responsible for producing ATP. It works by transferring electrons from ubiquinol to cytochrome c, and ultimately to complex IV.
The normal yield of ATP in a typical aerobic respiration process is around 36-38 ATP molecules. Therefore, if a poison is added to block complex III, the maximum number of ATP molecules that can be produced will be reduced to 38.
