RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When breakdown of glucose occurs with the use of oxygen it is called
A
aerobic respiration
B
anaerobic respiration
C
cellular respiration
D
anaerobes
Explanation: 

Detailed explanation-1: -Cellular respiration or respiration is the process by which cells breakdown glucose to release energy. Carbon dioxide and water are also released in the process. This can happen in the presence or absence of oxygen. When respiration takes place in the presence of oxygen, it is called aerobic respiration.

Detailed explanation-2: -The process of aerobic respiration completely breaks down glucose into carbon dioxide and water, whereas anaerobic respiration incompletely breaks down glucose into alcohol (alcohol fermentation) or lactic acid (lactic acid fermentation).

Detailed explanation-3: -Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.

Detailed explanation-4: -During aerobic respiration, glucose is first broken down to form carbon dioxide as an end product with the help of oxygen. This process releases ATP, the energy currency of the body.

Detailed explanation-5: -Anaerobic respiration usually occurs in lower plants and microorganisms. In the absence of oxygen, the glucose derived from food is broken down into alcohol and carbon dioxide along with the production of energy.
