What occurs under aerobic conditions?
Under aerobic conditions, glycolysis, β-oxidation of free fatty acids and the TCA cycle generate reducing equivalents (i.e. NADH + H+ and FADH2) which are oxidized in mitochondria owing to the ETS localized in the inner mitochondrial membrane.
Which of the following can occur under anaerobic conditions?
Under anaerobic conditions, regeneration of cell’s energy occurs through a series of metabolic reactions. This process is known as fermentation. Under anaerobic conditions, the Krebs cycle is blocked. Similarly, hydrogen is produced inside the cell for the maintenance of redox potential.
What processes does not occur under aerobic conditions?
One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis – the splitting of glucose. Glycolysis (see “Glycolysis” concept) is an anaerobic process – it does not need oxygen to proceed. This process produces a minimal amount of ATP.
Does fermentation only occur under anaerobic conditions?
View the question. Yeast are facultatively anaerobic which means that they perform fermentation only under anaerobic conditions. Certain bacteria are obligately anaerobic and can exist only in O2-free circumstances. In contrast, many organisms can only survive in aerobic conditions.
What are aerobic and anaerobic conditions?
Aerobic & Anaerobic Environments. An aerobic environment is characterized by the presence of free oxygen (O2) while an anaerobic environment lacks free oxygen but may contain atomic oxygen bound in compounds such as nitrate (NO3), nitrite (NO2), and sulfites (SO3).
Which of the following processes can occur under aerobic or anaerobic conditions?
The correct answer is a. Only glycolysis is the process that can occur in an oxygen-free (anaerobic) environment.
Which of the following processes will occur under both aerobic and anaerobic conditions?
Which of the following biological processes will occur under both aerobic and anaerobic conditions in humans? Explanation: The correct answer is glycolysis. Fermentation is a pathway that requires anaerobic conditions to activate.
What is aerobic and anaerobic process?
While both rely on a process of microbial decomposition to treat wastewater, the key difference between anaerobic and aerobic treatment is that aerobic systems require oxygen, while anaerobic systems do not.
Is fermentation aerobic or anaerobic?
Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that’s performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end.
Under what conditions is aerobic respiration most likely to occur?
It can occur only in the presence of oxygen. It is the formation of ATP by the flow of protons through a membrane protein channel.
What happens with NADH under aerobic conditions?
If there are aerobic conditions, meaning oxygen is available, the NADH molecule can be transported to the mitochondria where it can be immediately converted back to NAD and plays a role in the electron transport chain.
Where does Krebs cycle occur in aerobic and anaerobic conditions?
Occurs only under aerobic conditions Krebs Cycle, Cellular Respiration (Aerobic), Electron Transport Chain Uses Phosphorylation Glycolysis, Fermentation, Cellular Respiration (aerobic), Krebs Cycle, Electron Transport Chain Occurs under aerobic and anaerobic conditions Glycolysis
What is the difference between aerobic and anaerobic glycolysis?
It can occur aerobically or anaerobically depending on whether oxygen is available. This is clinically significant because oxidation of glucose under aerobic conditions results in 32 mol of ATP per mol of glucose. However, under anaerobic conditions, only 2 mol of ATP can be produced. Aerobic glycolysis occurs in 2 steps.
Why do we need anaerobic and aerobic conditions?
Aerobic Conditions Aerobic conditions are needed to oxidize ammonium ions to nitrate, then anaerobic conditions are required for the nitrate to be reduced to nitrogen gas which is removed from the system (Eyben et al., 1995). From: Brewing: Science and Practice, 2004
When does fermentation occur in aerobic and anaerobic conditions?
Fermentation Occurs only under aerobic conditions Krebs Cycle, Cellular Respiration (Aerobic), Electron Transport Chain Uses Phosphorylation Glycolysis, Fermentation, Cellular Respiration (aerobic), Krebs Cycle, Electron Transport Chain Occurs under aerobic and anaerobic conditions
