Answer 1

Definition of the given terms is provided below :

1. Nutrition

It is the nourishment that we are able to get when food substances are consumed by us. Maintaining a healthy diet provides us nutrition.

2. Nutrients

These are the compounds that are found in food items that our body obtains to function properly. Examples : Vitamins, fats, etc.

3. Proteins

It is a kind of nutrient that contains amino acids.

4. Cellular respiration

It is the process in which biochemical energy are transformed into ATP by cells.

5. Aerobic respiration

This is the kind of respiration where energy is produced in presence of oxygen.

6. Glycolysis

It is the phenomenon where glucose is broken to release pyruvic acid and energy.

Answer 2

$\huge\bold{ \pmb{ \color{cyan}{ \underline{RESPIRATION} \: :-}}}$

Respiration is the chemical process, which involves breathing in oxygen , breathing out carbon dioxide & breakdown of food using oxide to release energy.

DETAILED EXPLANATION

• All living organisms require energy to carry out various life processes . like nutrition, transport, excretion, reproduction, etc. This energy is stored in the food that we eat .

• In order to break down food to release energy oxidation of food takes place. This reaction takes place in the cells of the body of the organisms.

• The oxygen needed for the oxidation comes from the air that we inhale. This oxygen is then transported to every cell.

• Thus, the process in which food is broken down to release energy is called respiration. During respiration, carbon dioxide and water are released as waste - products.

Types of Respiration :-

• Aerobic respiration requires oxygen and releases lots of energy.
• Anaerobic respiration does not require oxygen and releases less energy.
