Question

Which describes the process of glycolysis?

Question 14 options:

aerobic process that breaks down glucose

aerobic process that manufactures glucose

anaerobic process that breaks down glucose

anaerobic process that manufactures glucose

Answer 1

Option 3rd. anaerobic process that breaks down glucose

Step-by-step explanation:

• On observing only glycolysis it is an anaerobic process. As none of the nine steps of glycolysis involve the use of oxygen.
• After, immediate finish of glycolysis, the cell continues respiration either in anaerobic or anaerobic direction this depends upon the presence of oxygen and mitochondria.
• If oxygen and mitochondria is present the glycolysis will be broken down to produce 2 molecule of pyruvate as the end product which will be utilized in further processes(in kreb's cycle and ETS).
• In case if oxygen is absent then different types of alcohols and and acids are formed.

Result: Glycolysis does not involve oxygen and hence is a anaerobic process.
