Assertion: Both hexokinase and glucokina...

Assertion: Both hexokinase and glucokinase require divalent cation `Mg^(++)` or `Mn^(++)`
Reason: The divalent cations act as catalysts.

A

If both the assertion and the reason are true and the reason is a correct explanation of the assertion

B

If both the assertion and reason are true but the reason is not a correct explanation of the assertion

C

If the assertion is true but the reason is false

D

If both the assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
C
In the first reaction of glycolysis the gamma phosphorus group of a ATP molecule is transferred to the oxygen at the C-6 of glucose the magnesium ion is required as the reactive form of ATP is the complex with magnesium ion. Hexokinase is the enzyme that catalyzes this phosphorus group transfer.
