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.
When glucose is catabolized under aerobic conditions will cross the mitochondrial wall and enter the Kreb's cycle?
Yes, when glucose is catabolized under aerobic conditions, it is converted to pyruvate through glycolysis in the cytoplasm. Pyruvate then enters the mitochondria where it is converted to acetyl-CoA, which enters the Krebs cycle to produce energy in the form of ATP through oxidative phosphorylation.
Does the Krebs cycle occur if glycolysis occurs?
Yes, the Krebs cycle occurs after glycolysis as part of cellular respiration. Glycolysis breaks down glucose into pyruvate, which then enters the mitochondria to be further broken down in the Krebs cycle to produce ATP and other molecules for energy production.
Does covering food retard bacterial growth?
No, bacteria can thrive under anaerobic conditions.
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.
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.
Does glycolysis operate under aerobic or anaerobic conditions?
It isn't, it is a strictly anaerobic process. However it may occur in organisms that use oxygen in a related process.
What is the recycling of NAD under anaerobic conditions?
Under anaerobic conditions, NAD can be recycled through fermentation processes that regenerate NAD+ from NADH. This allows cells to continue glycolysis and produce ATP in the absence of oxygen. Fermentation pathways, such as lactic acid fermentation or alcohol fermentation, are utilized to regenerate NAD for these anaerobic processes.
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.
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.
The conversion of nitrates back into free nitrogen by bacteria in the soil is?
called denitrification. This process releases nitrogen gas back into the atmosphere, completing the nitrogen cycle. Denitrification occurs under anaerobic conditions where bacteria use nitrates as an alternative electron acceptor in the absence of oxygen.
Which of these processes will occur in a human cell under low oxygen conditions?
Under low oxygen conditions, a human cell will undergo anaerobic respiration to produce energy in the form of ATP. This involves glycolysis followed by fermentation to generate ATP without the need for oxygen.
