C) Hexokinase III) Inorganic phosphate
D) Malate dehydrogenase IV) 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:

(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.

List-I | List-II | ||

The correct match is:


Assertion (): Anaerobic respiration yields less energy utilizing oxygen.
Reason (): In anaerobic respiration, energy is released due to the incomplete breakdown of organic molecules.
