16. During electron transport reactions a. OH- accumulates on the outside of the membrane while H accumulates on the inside. b. OH- accumulates on the inside of the membrane while H accumulates on the outside. c. both OH- and H accumulate on the inside of the membrane. d. both OH- and H accumulate on the outside of the membrane

Option B, OH- accumulates on the inside of the membrane while H+ accumulates on the outside.

Explanation:

In electron chain reaction, the electrons move through a series of electron transporters thereby undergoing redox reactions. This leads to accumulation of hydrogen ion (H+) with in the matrix and hence development of concentration gradient that leads to diffusion of hydrogen ion out of the matrix and accumulation of OH- ion on the inner side of the matrix while passing through ATP synthase

Hence, option B is correct

there's the proffessional site that will you.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
