Question

Identify the INCORRECT statement regarding glycolysis.

• A. It occurs in cytoplasm
• B. It is common to aerobic and anaerobic respiration.
• C. Glucose undergoes partial oxidation to form 2 molecules of pyruvic acid.
• D. The process is completed in a single phase through ten steps.

Hint:

Glycolysis is completed in two phases, not one.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Glycolysis is the breakdown of glucose to two pyruvic acid molecules in the cytoplasm.

Step 2: Check Statements A-C
It occurs in the cytoplasm, is common to aerobic and anaerobic respiration, and it is a partial oxidation giving 2 pyruvic acid.
So these are correct.

Step 3: Check Statement D
The ten steps are completed in two phases, the preparatory phase and the pay-off phase, not in a single phase.
So D is incorrect.

Final Answer:
The statement that glycolysis is completed in a single phase is incorrect. \[ \boxed{\text{(D) }\text{The process is completed in a single phase through ten steps.}} \]
