Why is there less energy in anaerobic respiration?

In anaerobic respiration, less energy is extracted. In this process only 02 ATP molecules are produced by each glucose molecule and the glucose molecules are partially broken down. The reaction yields less energy as compared to the aerobic respiration because the end product is alcohol and not carbon dioxide.

Why is anaerobic respiration less efficient than aerobic respiration?

Anaerobic respiration is respiration using electron acceptors other than oxygen. The latter ones have smaller reduction potentials than oxygen. This means that less energy is released per one oxidized molecule. That is why, anaerobic respiration is less efficient than aerobic respiration.

Why is the efficiency of fermentation is so low?

Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration. This is because most of the energy of aerobic respiration derives from O2 with its relatively weak, high-energy double bond.

What is the efficiency of anaerobic respiration?

Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.

Why is anaerobic respiration more efficient than fermentation?

The most efficient way is through aerobic respiration, which requires oxygen. This method gives the most ATP per energy input. Such processes that happen without oxygen are called anaerobic. Fermentation is a common way for living things to make ATP without oxygen.

Why is aerobic respiration more efficient in producing ATP than fermentation?

As aerobes in a world of aerobic organisms, we tend to consider aerobic respiration “better” than fermentation. Without oxygen, organisms can only break a 6-carbon glucose into two 3-carbon pyruvate molecules. As we saw earlier, glycolysis releases only enough energy to produce two (net) ATPs per molecule of glucose.

Which requires less energy aerobic or anaerobic respiration?

Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.

Does aerobic respiration requires less energy?

Explanation: Aerobic respiration needs more energy.

Which type of respiration is more efficient aerobic or anaerobic Why?

Aerobic respiration is more efficient than anaerobic respiration because aerobic respiration yields 6 times more energy as compared to anaerobic respiration.
