Question

The end products of aerobic respiration of glucose is-
A. \[{{C}}{{{O}}_{{2}}}{{ + }}{{{H}}_{{2}}}{{O + ATP}}\]
B. \[{\text{C}}{{\text{O}}_{\text{2}}}{\text{ + Pyruvic acid}}\]
C. \[{\text{C}}{{\text{O}}_{\text{2}}}{\text{ + ethyl alcohol}}\]
D. \[{\text{C}}{{\text{O}}_{\text{2}}}{\text{ + pyruvic acid + citric acid}}\]

Answer 1

Hint: The most abundant monosaccharide is glucose, which is a type of carbohydrate. The process in which cellular energy is produced through the presence of oxygen is called aerobic respiration. Glucose is chemically represented as \[{{C_6H_{12}O_6}}\].

Complete answer:
According to the equation for the aerobic conditions,
\[{{C_6H_{12}O_6 + 6O_2}} \to {{6CO_2 + 6H_20 + ATP}}\]
The energy is produced by splitting of the glucose molecule in the presence of oxygen. The end product formed by this reaction is six molecules of carbon dioxide, six molecules of water along with some energy produced as ATP (Adenosine triphosphate).

This type of respiration takes place inside the mitochondria. For the process of breaking the glucose molecule approximately 2900 kilojoules of energy gets released that forms the ATP. Aerobic respiration occurs in almost all the plants, animals and other living organisms. The oxygen gas enters the plant via stomata present on the epidermis in the leaves and stem.

Therefore, the end product of aerobic respiration is \[{{C}}{{{O}}_{{2}}}{{ + }}{{{H}}_{{2}}}{{O + ATP}}\].

On aerobic respiration of glucose, the end products like pyruvic acid, ethyl alcohol, and citric acid are not generated.

Hence, the correct answer is option (A).

Note: The different steps occurring in the process of aerobic respiration are glycolysis, formation of Acetyl coenzyme A, Citric acid cycle, and the electron transport chain. After the breakdown of glucose ATP is produced in the mitochondrial matrix, the pyruvate gets converted to acetyl CoA. For each glucose molecule, the Krebs cycle occurs twice. In the inner mitochondrial matrix the electron transport chain occurs.
