List-I | List-II | ||
A | Phosphoenol pyruvate | I | Hexokinase |
B | Pyruvic acid | II | Enolase |
C | Triosephosphate | III | Pyruvic kinase |
D | Glucose-—phosphate | IV | Aldolase |
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.


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:


Assertion (A): When electrons move through the transport chain, protons are transported across the membrane.
Reason (R) : Because the primary acceptor of electron located towards the outside of the membrane, transfers its electrons to a H carrier (PQ).
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.

A) Cytochrome is a small protein attached to inner surface of the outer membrane
B) Electrons from complex I are transferred to ubiquinone located within the inner membrane
C) The temperature optimum for photosynthesis of different plants does not depend on the habitat that they are adapted to.
D) There is no linear relationship between incident light and fixation rates at low light intensities.
