EASY

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:

HARD
Give an account of glycolysis. Where does it occur? What are the end products of glycolysis? Trace the fate of these products in both aerobic and anaerobic respiration.

(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.

Which ONE of the following statements is INCORRECT about the hexokinase-catalysed reaction given below?

Glucose + ATP Glucose-6-phosphate+ADP

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.
