NEET BIOLOGY

Detailed explanation-1: -The oxygen we inhale is used to breakdown glucose into carbon dioxide and water. Energy is released in the process. The breakdown of glucose occurs in the cells of an organism (cellular respiration). If the food is broken down with the use of oxygen, it is called aerobic respiration.

Detailed explanation-2: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. 8.

Detailed explanation-3: -Briefly: In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy “powerhouses” of the cells (Figure below).

Detailed explanation-4: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Detailed explanation-5: -During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP.
