Question

explain wt is respiration

Answer 1

Answer:

Respiration: The process of releasing energy by the oxidation of food is known as respiration. Respiration is of two types aerobic and anaerobic.

Aerobic respiration:

i. Respiration which takes place in the presence of oxygen is known as aerobic respiration.

ii. During this process, food (glucose) is broken down into carbon dioxide and water in the presence of oxygen.

iii. Energy release in this process is stored in the form of adenosine triphosphate (ATP).

Anaerobic respiration:

i. Respiration which takes place in the absence of oxygen is known as anaerobic respiration.

ii. In anaerobic respiration in microorganisms, glucose is broken down into ethanol and carbon dioxide with the release of energy. Lactic acid is the end-product of respiration in muscle cells, while CO$$_2$$CO2 and ethanol are formed in plants.

Answer 2

Required Answer:

☑ Respiration is a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing (which is properly called ventilation).
