Question

How many ATPs are produced during anaerobic respiration?

Answer 1

Anaerobic respiration is the process of generating energy in the absence of oxygen and it takes place inside the fluid portion of the cytoplasm. It is a method in which a large amount of energy is transferred quickly.

Complete answer:
In this type of respiration electron acceptors are used rather than molecular oxygen for energy production. Anaerobic respiration occurs in the absence of oxygen to metabolize glucose and produce ATP. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.

In glycolysis, after the formation of pyruvate the process then further depends on availability of oxygen. After pyruvate arrangement, if oxygen is accessible the formed pyruvate enters the mitochondria and is totally oxidized to carbon dioxide. Without oxygen, it enters the anaerobic breath where it is changed over to lactate.

Pyruvate is subsequently reduced to lactate (lactic acid) by NADH, leaving NAD+ after the reduction. This reaction is catalyzed by the enzyme lactate dehydrogenase. This essentially leads to the recycling of NAD+. Anaerobic glycolysis happens faster than aerobic because less energy is produced for every glucose broken down, so more must be broken down at a faster rate to meet demands. This may lead to lactic acidosis.

Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen. Within the human body, both aerobic and anaerobic respiration are important to muscle function. In aerobic respiration, the net arrangement of ATP 5 .Under anaerobic conditions, the NADH isn't changed over to ATP; subsequently, the net creation of ATP is just 2 ATP.

Note: There are two types of respiration,
Aerobic respiration: It is a cellular respiration which takes place only in the presence of oxygen to produce energy and the end products of this are water and ATP
Anaerobic respiration: It is a cellular respiration which takes place in absence of oxygen and the end products are Alcohol, carbon dioxide and energy.
