20 pts! why is anaerobic respiration energetically less efficient than aerobic respiration?

the aerobic respiration process uses a respiratory electron transport chain, while anaerobic respiration uses a molecular electron transport chain.

anaerobes use less oxidizing substances like sulfate or nitrate during the electron transport chain so less energy is released per oxidized molecule.

anaerobes use only oxygen during the electron transport chain, while aerobes use both oxygen and carbon dioxide which results in a more efficient process.

anaerobes' terminal electron receptors have larger reduction potentials than o2 meaning that more energy is released per oxidized molecule.

Anaerobes use less oxidizing substances like sulfate or nitrate during the electron transport chain so less energy is released per oxidized molecule.

Explanation:

Anaerobes use fewer oxidizing substances such as sulfate or nitrate during the electron transport chain, so less energy is released per oxidized molecule. This is because unlike aerobic respiration, in the anaerobic process there is no need for oxygen and glucose will be formed from the body's own food or reserves.

In this process of metabolic function there is no presence of oxygen and the energy comes from the ATP molecule, formed by the adenine nitrogen base, sugar, and three phosphates. This connection, when necessary, is broken for the release of energy.

In this case, glucose will originate from food or reserves created by the body itself. Thus, in the cell cytosol, this substance undergoes several reactions, caused by various enzymes, and then pyruvate, also used in aerobic respiration, will be generated. During the anaerobic respiration process, the ADP (adenosine phosphate) molecule receives a phosphate. After this, ATP formation occurs.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
