RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cells in the body use oxygen for cellular respiration. Which is the result of cellular respiration?
A
ATP is produced and carbon dioxide is released.
B
ATP is consumed and carbon dioxide is released.
C
ATP is produced and carbon dioxide is absorbed.
D
ATP is consumed and carbon dioxide is absorbed.
Explanation: 

Detailed explanation-1: -The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

Detailed explanation-2: -In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

Detailed explanation-3: -During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

Detailed explanation-4: -net yield of 34 ATP per glucose molecule.
