Answer 1

Answer=

Question 1 the following statements is true

• Catabolism is the breakdown of large molecules into smaller ones.Energy is generally released during catabolism.

Explanation=The metabolism consists of two processes anabolism and catabolism.

The Catabolism is the breakdown of large molecules into smaller ones.

example- larger polysaccharides such as starch is breakdown into glucose

Peptides are breakdown into amino acids.

during catabolism energy is released i.e. ATP is converted into ADP and Pi

Ababolism is the formation of larger substances from simple one energy is gained during anabolism.

Question 2 ]

In metabolic pathways, the interconversion of __ATP and _ADP_is the most important process for the storage and release of energy.

• ATP and ADP

Explanation = In metabolism ,for example in breaking down of glucose releases energy,which is captured by the cell in the form of adenosine triphosphate or ATP.

ATP is the small molecule that stores energy.

there is interconversion of ATP to ADP.

when we require energy,then ATP is broken down into ADP.

===============================================================================================

Question 3.

the following statements is true

• Energy is released when ATP is hydrolyzed to form ADP.

Explanation - When we require energy,the stored energy in the form of ATP is released.

when one of the phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis,energy is released,and ATP is converted to adenosine diphosphate(ADP).

ATP    ADP +pi + energy
