C | Triosephosphate | III | Pyruvic kinase |
D | Glucose-—phosphate | IV | Aldolase |
The correct match is:

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): ATP is used at two steps in glycolysis.
Reason (R): First ATP is used in converting glucose into glucose-6-phosphate and second ATP is used in conversion of Fructose-6-phosphate to Fructose-1,6-diphosphate.
In the light of the above statements, choose the correct answer from the options given below:



(A) Glycolysis has chain reactions.
(B) In glycolysis, ATP is utilised in one step.
(C) There is one step related to the formation of .
(D) Glycolysis can take place in the mitochondria matrix also.


Which ONE of the following statements is INCORRECT about the hexokinase-catalysed reaction given below?
Glucose ATP Glucose--phosphate+ADP

Assertion (A) :- The pathway from glucose to lactic acid occurs in metabolic steps. Organisms will trap this energy and store in the form of chemical molecules.
Reason (R) :- Glucose is the only substrate for the production of energy.
The correct option among the following is:

Respective products released along with main product in biochemical reactions catalysed by given enzymes
A) Glutamine synthetase I) NADH + H+
B) Fructose 1,6-bisphosphatase II) ADP + Pi
C) Hexokinase III) Inorganic phosphate
D) Malate dehydrogenase IV) ADP
