Answer 1

The functional activities that result in growth and repair of body tissue are called metabolism.

This function consists of two processes that have opposite effects, namely: catabolism and anabolism.

The taking in of food and oxygen and occurs in the anabolism

state which builds up complex

materials from simpler ones. The release of energy and carbon dioxide occurs in the catabolism state which is the breaking down of complex

substances into simpler ones. These functions require a stable, environment, maintaining this internal environment is known as homeostasis

For living organisms to function properly, there is need for a perfect and stable internal environment. These functional activities require a homeostatic role to work effectively

Metabolism

In all living organisms be it plants or animals, the complete sum total of all the chemical reactions which occurs in them to ensure the continuity of life processes is known as metabolism.

Let me make it more clearer to you, chemical activities and processes in living organisms such as osmosis, diffusion, turgidity, flaccidity, phagocytosis, homeostasis, cell division, autotrophism, heterotrophism, photosynthesis, digestion, respiration, excretion, growth, reproduction are absolutely all processes of metabolism.

In my own book, I describe metabolism as the mother of all activities in living organisms

Be that as it may, the fundamental purpose ofmetabolism are;

• Conversion of the energy in food to energy available to run life cellular processes
• Conversion of food to building blocks for proteins, lipids, nucleic acids and others
• Elimination of metabolic wastes

So therefore, the functional activities that result in growth and repair of body tissue are called metabolism.
