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.

What is the energy brought by electron carriers to the<br> mitochondria used for?
Nonamiya [84]

Answer:

The correct answer will be- to synthesise the ATP molecules in respiration process.

Explanation:

The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.

The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.

The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.

Thus, to synthesise the ATP molecules in the respiration process.
