Question

1. Why do we respire ?
2. What gets oxidised to carbon dioxide during aerobic respiration?
3. Which chemical gets accumulated in the muscles of humans during anaerobic res
4. Which of the two types of respiration produces more energy?​

Answer 1

Answer:

1.All cells in our body need oxygen to create energy efficiently. When the cells create energy, however, they make carbon dioxide. We get oxygen by breathing in fresh air, and we remove carbon dioxide from the body by breathing out stale air.

2. During aerobic respiration, the oxygen taken in by a cell combines with glucose to produce energy in the form of Adenosine triphosphate (ATP), and the cell expels carbon dioxide and water. This is an oxidation reaction in which glucose is oxidized and oxygen is reduced.

3. latic acid

4.Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.

Answer 2

Answer:

1. 1 The food has stored energy released at the time of respiration. Thus, all the living organisms respire to get energy from food. During breathing, we breathe in the air. We also know that air contains oxygen.
2. During aerobic respiration, the oxygen taken in by a cell combines with glucose to produce energy in the form of Adenosine triphosphate (ATP), and the cell expels carbon dioxide and water. This is an oxidation reaction in which glucose is oxidized and oxygen is reduced.
3. Lactic acid, or lactate, is a chemical byproduct of anaerobic respiration — the process by which cells produce energy without oxygen around. Bacteria produce it in yogurt and our guts. Lactic acid is also in our blood, where it's deposited by muscle and red blood cells.
4. Summary. Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per gl
