Why does the body switch between cellular and anaerobic respiration?
Wiki User
∙ 11y ago
The body needs oxygen for cellular respiration. When doing strenuous activity, such as lifting weights, the mitochondria cannot get enough oxygen. Without oxygen to act as an electron receptor, the body creates lactic acid to "reset" coenzymes to continue respiration.

What process occurs if oxygen is not available?
If oxygen is absent in cellular respiration, then you go to anaerobic respiration. Anaerobic respiration that still uses the electron transport chain., but without oxygen.
How are aerobic respiration anaerobic respiration different?
aerobic respiration uses oxygen and anaerobic doesn't; also aerobic produces more ATP or cellular energy***Apex: Oxygen is necessary for aerobic respiration but not for anaerobic respiration.
Is there anaerobic respiration in plants?
When oxygen supplies cannot be kept up and the oxidative metabolism cannot produce all the ATP required, there is a switch to processes that break down glucose and glycogen to lactic acid which diffuses into the blood stream. Creatine phosphate is a substance that aids in the formation of ATP rapidly. Creatine phosphate + ADP <>ATP + creatine
What is the process that release energy when oxygen is insufficient?
ANAEROBIC RESPIRATION is how the cells produce ATP when no oxygen is present: Anaerobic (fermentation) vs. Aerobic Respiration i. Without oxygen to accept electrons in the electron transport chain, most of cellular respiration stops. ii. Fermentation enables some cells to produce ATP in the absence of oxygen. iii. In glycolysis, glucose is oxidized to two pyruvate molecules with NAD+ being reduced to NADH. iv. Pyruvate then accepts electrons from NADH, oxidizing it back to NAD+. The NAD+ is then available to oxidize more glucose. v. Because the pyruvate does not enter the Krebs cycle, there is still a lot of energy which is not removed from the fuel. This is evident in yeast fermentation where the end product is alcohol - a high energy fuel. vi. Human muscle cells switch from aerobic respiration to lactic acid fermentation to generate ATP when O2 is scarce. When O2 is absent, the ETC stops; therefore pyruvate accepts electrons, forming lactic acid. This waste product causes muscle fatigue and cramping, but it is eventually converted back to pyruvate in the liver. vii. Under aerobic respiration, a molecule of glucose yields 36-38 ATP, but the same molecule of glucose yields only 2 ATP under anaerobic respiration. Hope this helps. it is a section out of my biology notes. If it doesnt, google Anaerobic respiration and wiki will give you a good answer
How do cells determine if they use cellular respiration or fermentation?
At the completion of the glycolic process, pyruvic acid is produced. Some of the pyruvic acid ends up in the cell mitochondria where cellular respiration takes place. In the absence of oxygen, the pyruvic acid goes through a process of fermentation, which takes place in the cytoplasm of the cell.

Facultative anaerobes can switch between cellular respiration and?
Capable of switching to fermentation
What is an end product in muscle cells during exercise?
During gentle or moderate exercise, the products of cellular respiration of glucose are carbon dioxide and water (CO2 + H2O), just as in other cells.But if the exercise is vigorous, the muscle cells can switch to anaerobic cellular respiration (fermentation), in which case they convert each molecule of glucose into two of lactic acid.Later, most of the lactic acid is converted back to glucose.

How do an animal's cells react when there is no glucose available to carry out cellular respiration?
They switch to using lipids and proteins as -CH2- sources, and change to a Cellular-Material-Scavenging Mode.
When will a cell break down glucose anaerobically?
If you break down the word aerobic: aero- "air" + bios "life". So aerobic organisms live on the presence of air, specifically oxygen. The prefix ana- is a negation, so anaerobic organisms do not require oxygen for respiration. Some organisms (called facultative anaerobes) are able to switch from aerobic to anaerobic respiration. The determining factor in the switch from aerobic to anaerobic would be the presence of oxygen. If there is no oxygen, then facultative anaerobes will respire anaerobically.
What is the major adaptive advantage for cellular respiration?
Since some organisms are able to switch metabolic pathways depending on if oxygen is available they have an adaptive advantage. For other organisms if there is no oxygen then there is no respiration.
What is aerobic cellular repiration?
A) glucose → lactic acid + energy B) energy + carbon dioxide + water → glucose + oxygen + water C) glucose → ethyl alcohol + carbon dioxide + energy D) glucose + lactose → galactose + water E) glucose + oxygen → carbon dioxide + water + energy From sallydeath
Will the Nintendo Switch have cellular service?
No, the Nintendo Switch is a gaming console and does not support cellular services
