Question:
Which one of the following is a correct statement?
Which one of the following is a correct statement?
Show Hint
Check each statement against the steps of glycolysis and fermentation.
Updated On: Nov 13, 2026
There is complete breakdown of glucose in fermentation.
Pyruvic acid is formed in the mitochondrial matrix during respiration.
Enzyme enolase catalyses the conversion of 2-phosphoglycerate to phosphoenolpyruvate.
Fructose - 6 - phosphate is converted to fructose 1,6 diphosphate by enzyme isomerase.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Glycolysis takes place in the cytoplasm and the enzymes catalysing each step are fixed.
Step 2: Check each statement
In fermentation glucose is only partially broken down, so the first statement is wrong.
Pyruvic acid is formed in the cytoplasm, not the mitochondrial matrix.
Fructose-6-phosphate is converted to fructose 1,6-bisphosphate by phosphofructokinase, not isomerase.
Enolase converts 2-phosphoglycerate to phosphoenolpyruvate.
Step 3: Compare the options
The enolase statement is correct.
Final Answer:
The statement about enolase converting 2-phosphoglycerate to phosphoenolpyruvate is correct. \[ \boxed{\text{(C) }\text{Enzyme enolase catalyses the conversion of 2-phosphoglycerate to phosphoenolpyruvate.}} \]
