Question

Can we relate metabolism with growth of the body?

Answer 1

Metabolism is the growth of body.
We know,
Metabolism is the chemical processes that occur within a living organism in order to maintain life.

Metabolism includes synthesis of ATP, processes of respiration, photosynthesis(in plants) , digestion(in animals) , synthesis of proteins etc.

So, all chemical processes from digestion respiration to excretion is included in metabolism.

We know, growth in animals is not just growth in body mass, but also growth of skills, memory, reproduction etc.

In plants, growth means gain in mass, height, reproduction, etc.

Plants need carbohydrates to grow, stem, cells, etc are essentially made of, ,Carbohydrates and proteins.
For animals, building block is protein. All these protein and carbohydrate synthesis are metabolic activities.

So, metabolism is proportional to growth. More metabolism, more grown. When we grow old, metabolism decreases, so we eventually die, when our body is incapable of maintaining required metabolic rate.

Scientists are trying of ways to increase metabolism, so that we can increase our life span.
