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

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

Glucose + ATP Glucose-6-phosphate+ADP

How many ATP molecules are produced when DHAP of EMP path enters the oxidative phosphorylation?
EASY
The number of electrons required to reduce one molecule of oxygen to water during mitochondrial oxidation is:
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.
