Question

Q3. Which of the following does not happen during glycolysis?

(a) Phosphorylation

(b) Oxidative decarboxylation

(c) Isomerisation

(d) Dehydrogenation​

Answer 1

Glycolysis is the metabolic pathway that converts glucose into pyruvate. During glycolysis process, 2 ATP molecules and 2 NADH molecules are produced. FADH is not produced during glycolysis.

Answer 2

Answer:

Concept:

The metabolic pathway that converts glucose to pyruvate is known as glycolysis.

Explanation:

• Glycolysis is a universal pathway found in all organisms, including yeast and mammals.
• Glycolysis occurs in the cytosol of eukaryotes.
• Glycolysis is anaerobic; it does not require oxygen.
• In the presence of O2, pyruvate is further oxidised to CO2.
• Two ATP molecules and two NADH molecules are produced during the glycolysis process. FADH is not synthesised during glycolysis.
• Pyruvate can be fermented to lactate or ethanol in the absence of oxygen.

So during glycolysis, oxidative decarboxylation does not occur.
