Anaerobic conditions in animals pyruvate is converted to what?
In animals under anaerobic conditions, pyruvate is converted to lactate through the process of lactate fermentation. This process helps regenerate NAD+ to continue glycolysis in the absence of oxygen.
Why are lactate and ethanol formed under anaerobic conditions?
Short Answer: To regenerate NAD+ for the continued function of glycolysis.Detailed Answer: As NADH is formed in glycolysis (2 NADH per glucose), NAD+ must be regenerated to allow continued glycolytic flux (and consequent production of ATP). In the presence of adequate oxygen (i.e. under aerobic conditions), this regeneration takes place predominantly in the mitochondria. Under anaerobic conditions, however, the only way to regenerate NAD+ is through lactate fermentation (e.g. mammals) or ethanol fermentation (e.g. yeast).
Fermentation enables glycolysis to continue under what conditions?
Fermentation enables glycolysis to continue in the absence of oxygen, allowing for the regeneration of NAD+ to sustain ATP production. This process is particularly important in anaerobic conditions where aerobic respiration is not possible.
Can a human survive from only using anaerobic respiration?
No, a human cannot survive solely on anaerobic respiration. While anaerobic respiration can provide short bursts of energy in the absence of oxygen, it is not sustainable for long-term survival. Anaerobic respiration produces lactic acid as a byproduct, which can lead to muscle fatigue and eventually organ failure if oxygen is not reintroduced to the body. Oxygen is essential for the efficient production of ATP, the body's primary energy source, through aerobic respiration.
1 The anaerobic pathway that follows glycolysis in the absence of oxygen is fermentation -- True or false?
True. Fermentation is the anaerobic pathway that follows glycolysis in the absence of oxygen, allowing for the regeneration of NAD+ to continue glycolysis.
Does the recycling of ATP ensure the continuation of glycolysis under anaerobic conditions?
Yes, the recycling of ATP ensures the continuation of glycolysis under anaerobic conditions by providing the necessary energy for the reactions to proceed. This is particularly important in anaerobic conditions where the final products of glycolysis cannot be further metabolized through aerobic respiration for additional ATP production.
What is the recycling of NAD plus under anaerobic conditions?
Under anaerobic conditions, NAD+ can be regenerated through fermentation processes that do not require oxygen. During fermentation, pyruvate produced from glycolysis is converted into various end products like lactate or ethanol, which helps regenerate NAD+ from NADH. This allows for continued glycolysis and ATP production in the absence of oxygen.
Why the Krebs cycle does not run under anaerobic conditions?
Because NAD+ level will decrease if oxygen is not present to regenerate NADH to NAD + Because NAD+ level will decrease if oxygen is not present to regenerate NADH to NAD +

What happens to pyruvate under anaerobic and aerobic conditions?
In humans, under ANAEROBIC conditions (no O2), pyruvate is 'converted' to lactate, though I wouldn't say it is "broken down".In humans, under AEROBIC conditions (O2 present), pyruvate is converted to Acetyl-CoA, via the pyruvate dehydrogenase reaction.In yeast, pyruvate is converted into ethanol (Party Fluid) via pyruvate decarboxylase and then alcohol dehydrogenase.
What terminal electron acceptors are used in anaerobic cellular respiration?
anaerobic cellular respiration has 3 different stages, and their final electron acceptors are: pyruvate oxidation- NAD+ Krebs cycle- NAD+, FAD+ electron transport chain- Oxygen
What is recycled in fermentation?
In fermentation, the primary substances recycled are NADH and NAD+ molecules, which are crucial for maintaining the balance of electron carriers during the process. Specifically, NADH is oxidized back to NAD+ during the conversion of pyruvate to various end products, such as ethanol or lactic acid, depending on the type of fermentation. This recycling allows glycolysis to continue, enabling the organism to produce energy even in anaerobic conditions. Additionally, carbon dioxide may also be released and can be utilized in other biological processes.
What energy-carrier molecules are produced by glycolysis?
NADH and ATP
Can a human survive from only using anaerobic respiration?
No, a human cannot survive solely on anaerobic respiration. While anaerobic respiration can provide short bursts of energy in the absence of oxygen, it is not sustainable for long-term survival.

Oxygen is essential for the efficient production of ATP, the body's primary energy source, through aerobic respiration.
What happens to pyruvate when there is no oxygen?
During anaerobic conditions, pyruvate is converted to lactic acid or ethanol via fermentation pathways to regenerate NAD+ for glycolysis to continue. This process does not produce additional ATP and is less efficient than aerobic respiration.
