and energy can be produced

Answer 2

• Cells make up a person's entire body. Nutrition, excretion, transport, and reproduction are some of the functions performed by cells.
• To carry out these activities, they require energy. The food we eat supplies this energy.
• Food contains energy. Respiration allows this energy to be released.
• We get oxygen from the air we breathe. It travels through the body, eventually reaching the cells.
• The meal gets disintegrated with the help of oxygen in the cells. Energy is released as a result of this. Cellular respiration refers to this process.
• With the aid of oxygen, the food in the cells disintegrates into water and carbon dioxide.
• Aerobic respiration is the term for the process of breaking down food in the presence of oxygen.
• Anaerobic respiration is defined as the disintegration of food without the use of oxygen. The decomposition of food releases energy.
