Answer 1

Answer:

1) a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

2) During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate)

3)There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be utilized in the presence of oxygen, while anaerobic respiration does not require oxygen.

Answer 2

1. Respiration is the process by which living things produce energy from food. Respiration usually needs oxygen.

2. The energy produced during respiration is stored in the form of ATP molecules in the cells of the body and used by the organism as when required.

3. There are two types of cellular respiration:-

• Aerobic respiration=> Aerobic respiration is more efficient and can be utilized in the presence of oxygen

• Anaerobic respiration=> Anaerobic respiration does not require oxygen.

4. The two different types of aerobic respiration are:-

• Alcoholic fermentation

• Lactic acid fermentation

5. Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.

6. Respiration is essential for life because as a result of exchange of gases oxygen is supplied to our body which is very essential for obtaining energy as for releasing energy glucose needs to be broken down (oxidized) in the presence of oxygen.
