Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside. Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.

____________ is a membrane protein that catalyzes the energy requiring synthesis of ATP from ADP and inorganic phosphate.
olasank [31]

Answer:

The correct answer will be option-C.

Explanation:

The production of ATP from ADP and Pi (inorganic phosphate) catalyzed by an enzyme known as ATP synthase.

ATP synthase is made up of two main regions called F₀ and F₁ in which F₀ is embedded in the membrane and acts as a pump through which proton flux takes place. The F₁ unit is the rotating unit of the ATP synthase which rotates due to energy provides by the protons during proton flux.

When proton moves through F₀  unit down their concentration gradient, it provides energy to the F₁ subunits which bind ADP and inorganic phosphate to release ATP.

Thus, Option-C is the correct answer.
