Question

What are the three major phases of glycolysis?

Answer 1

Answer

Explanation:

The glycolytic pathway can be divided into three stages:

(1) glucose is trapped and destabilized;

(2) two interconvertible three-carbon molecules are generated by cleavage of six-carbon fructose;

(3) ATP is generated.

Answer 2

Dear Student,

◆ Glycolysis -

• Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism.
• Glycolysis converts glucose into pyruvate in 10 steps.
• Glycolysis is an anaerobic process & takes place in cytoplasm itself.
• Glucose, fructose or other sugars are involved as reactants in this process.
• Products formed are 2 pyruvate, 2 NADH & 2 ATP.

# Three major stages of glycolysis -

(1) Investment phase -

• Glucose is converted to fructose-1,6-bisphosphate.
• Glucose is trapped inside cell and converted to unstable form.

(2) Cleavage phase -

• Fructose-1,6-bisphosphate is cleaved 2 molecules of glycerladehyde-3-phosphate.

(3) Harvesting phase -

• Glycerladehyde-3-phosphate is converted to puruvate.
• ATPs are generated.

Thanks dear. Hope this helps you..
