Answer 1

Answer:

(D) Both Does not occur in the presence of O2 and May result in the formation of two moles of lactate for each mole of glucose

Explanation:

Glycolysis

Glycolysis is a metabolic pathway and anaerobic energy source that has evolved in almost all types of organisms. Another name for the process is the Embden-Meyerhof path, which names the main contributors to the discovery and understanding of the process. Although it does not require oxygen, so it is designed for anaerobic respiration, it is also the first step in cellular respiration. The process involves the oxidation of glucose molecules, the most important organic fuel for plants, microbes and animals. Most cells prefer glucose (although there are exceptions, such as acetic acid bacteria, which prefer ethanol). Glycolysis uses 2 ATP molecules, resulting in ATP, 2 NADH, and 2 pyruvate per glucose molecule. Pyruvate can be used in the citric acid cycle or act as a precursor for other reactions.

Option (A): Does not occur in the absence of 02

The above option is incorrect because glycolysis is an anaerobic pathway that means it occur in the absence of Oxygen.

Option (B): Does not occur in the presence of Oxygen (02)

The above option is correct because glycolysis is an anaerobic pathway that means it occur in the absence of Oxygen.

Option (C): May result in the formation of two moles of lactate for each mole of glucose

The above option is also correct because it helps in the formation of two moles of pyruvate or lactate.

Option (D): Both Does not occur in the presence of O2 and May result in the formation of two moles of lactate for each mole of glucose

The above option is most appropriately correct because glycolysis forms two moles of pyruvate or lactate for each mole of glucose and occur in the absence of Oxygen. It includes both option (B) and (C).

Therefore, for the above question option (D) both Does not occur in the presence of O2 and May result in the formation of two moles of

Therefore, for the above question option (D) both Does not occur in the presence of O2 and May result in the formation of two moles oflactate for each mole of glucose is correct.
