Answer 1

(1)=cellular respiration is a process of oxidising food molecule to carbon dioxide & water.

(2)= oxygen & glaucose are reactent of cellular respiration.

(3)carbon dioxide & water & energy are product of cellular respiration.

(4)=(a)=calorie is a unit of energy.calorie is define as amount of heat required at a pressure of 1 atmosphere to raise the temp.of 1 gram of water.

(B) cellular respiration= is a process of oxidising food molecule like glaucose into carbon dioxide & water

(C)=any process which depend on oxygen is called as aerobic.

(D)= process which can occir in the absence of oxygen.

(E)=fermentation is the process of converting carbohydrate into alcohol or organic acid..

(6)=3 stages of cellular respiration are glycolysis,electron transport chain & citric acid cycle.these stages occur in mitochondria.

(7)=ans.is same as (E) part of qus.no.4.
