Answer:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

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.
