Speed up

Slow down

Remain the same

The correct answer is In the presence of Antinomycin the Citric Acid Cycle would SLOW DOWN.

Explanation:

Actinomycin is an antibiotics gotten from streptomyces which is use to inhibit which inhibit mitochondriisl eclectron transport chain.It is a poison that affect the electron transport chain, non functional and it slow down citric acid cycle because it has the ability to block the electron Transport chain thereby slowing down citric acid cycle because it inhibit or slow down succinate-cytochrome c reductase in the electron transport chain so as to block the oxidation of NADH and ATP production.
