Answer 1

ANSWER:-

Question:21) b,high energy electron to high energy phosphate bonds.

In ETC high energy electron are entered from required coenzyme (NAD and FADHZ) When these electrons move through ETC, they loose their energy and this energy is used to pump proton in to inter mention space and generate PMF.

Question:22) option c, standard reduction potential

All complex of ETC are arranged according to their reduction potential.

They are arranged more negative towards more positive. More negative means have more reducing capacity. Mire positive means more oxidative capacity.

Question:23) option c, inter membrane space

During ETC, as electron moves through ETC complex. Energy is released which is used to pump protons in to inter membrane space and generate proton motive force.

Question:24) a, extracellular space

This space present in between plasma membrane and cell wall. As bacterial ETC is located on plasma membrane so if pumps proton in to extracellular space and generate proton motive force.

Question:25) b, plasma membrane.

In prokaryotic cellular organelles are not present. so here in bacteria their plasma membrane invagintes and form loop like structure. All the ETC enzyme are present in this part at plasma membrane.
