EASY
Muscle fatigue is caused due to accumulation of this substance in the muscle
EASY
Which of the following conversions in glycolysis is an example of substrate level phosphorylation?
EASY
Glycolysis is the breakdown of glucose to pyruvic acid. How many molecules of pyruvic acid are formed from one molecule of glucose?
EASY

Assertion (A) :- The pathway from glucose to lactic acid occurs in 10 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:

HARD
Identify the wrong statement related to glycolysis.
(A) Glycolysis has 10 chain reactions.
(B) In glycolysis, ATP is utilised in one step.
(C) There is one step related to the formation of NADH+H+.
(D) Glycolysis can take place in the mitochondria matrix also.
MEDIUM
Match the following lists.
  List-I   List-II
A Phosphoenol pyruvate I Hexokinase
B Pyruvic acid II Enolase
C Triosephosphate III Pyruvic kinase
D Glucose-6—phosphate IV Aldolase

The correct match is:

EASY
Which ONE of the following conversions does NOT happen under anaerobic conditions?
MEDIUM

Assertion (A): Anaerobic respiration yields less energy utilizing oxygen.

Reason (R): In anaerobic respiration, energy is released due to the incomplete breakdown of organic molecules.

HARD
