Important Questions on Respiration in Plants




Respective products released along with main product in biochemical reactions catalysed by given enzymes
A) Glutamine synthetase I) NADH + H+
B) Fructose 1,6-bisphosphatase II) ADP + Pi
C) Hexokinase III) Inorganic phosphate
D) Malate dehydrogenase IV) ADP

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

Which ONE of the following statements is INCORRECT about the hexokinase-catalysed reaction given below?
Glucose ATP Glucose--phosphate+ADP

(A) Acetaldehyde Ethanol
(B) Glyceraldehyde Phosphate - phosphoglyceric acid
(C) Pyruvic acid lactic acid
(D) Oxalosuccinic acid ketoglutaric acid
(E) ketoglutaric acid succinyl





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) Triose bis Phosphate to triose phosphate
B) Phosphoglycerate to Phosphoenol pyruvate
C) Succinyl CoA to Succinic acid
D) Malic acid to
