Explanation / Answer

1-A catabolic pathway is a system that releases energy i n the form of energy such as ATP,GTP,NADH etc...

Two parts are

a)Sources-carbohydrates,fats

b)-end products-carbondioxide,water,ammonia

2)

a)The anabolism process involves requirement of energy to construct macromolecules such as polypeptides,proteins,nucleic acid

b)The isolated reaction is unfavourable in the cell due to positive Gibb's energy

c)The catabolic activity lowes the activation energy of anabolism.

d)An anabolic pathway involves smaller molecules to form larger and complex molecules.

e)Anabolism is reverse pathway of glycolysis.

3)a)Catabolic pathway within all living organism in some form.

b)It occurs during cellullar respiration.

c)All cells can perform anaerobic respiration by glycolysis.

4)It is nothing but catabolic pathway releases chemical energy in the form of NADH.Catabolic pathway transfer the energy relesed by breakdown of nutrients into ATP and other small molecules used for energy.

6)In catabolic pathway carbondioxide produced in mitochondria

b)It also produced inside cell as an end product after net reaction

7)The living system uses molecule to store and transfer energy is

a)-ATP=Adenosine Triphosphate

b)Glucose

c)Starch

d)ADP

9) it reacts with citric acid cycle and oxodative phosphorylation
