Answer:
Respiration is the cellular process which converts glucose and oxygen into water and carbon dioxide with releasing an appropriate amount of energy.
Step-by-step explanation:
- We eat food mainly to get energy. That energy is used for cellular metabolism like Cellular reproduction, Cell repairing, new cell formation and in cellular metabolisms.
- So our food is first converted into glucose and we also get oxygen from air (mechanical respiration).
- Hence that glucose and oxygen reacts together in a metabolism known as respiration producing water, carbon dioxide and energy.
- It occurs in mitochondria of cells.
