Question

End products of aerobic respiration are
A) Sugar and oxygen
B) Water and energy
C) Carbon dioxide, water and energy
D) Carbon dioxide and energy

Answer 1

Hint:Respiration is the metabolic reactions occurring in the cells to convert chemical energy from oxygen or nutrients into ATP (adenosine triphosphate). Catabolic reactions involved in respiration which break the large molecules into small molecules. This reaction occurs in a series of biochemical processes and some are redox reactions.

Complete answer:
In cellular respiration oxygen and glucose are reactants that yield ATP. The byproducts are water and carbon dioxide.
The parts of Respiratory system are:
->Nose
->Mouth
->Pharynx
->Larynx(Voice box)
->Trachea
->Airways
->Lungs
Aerobic respiration requires oxygen to create ATP. Carbohydrates, fats and proteins are required as reactants and aerobic respiration is the preferred method for glycolysis (pyruvate breakdown). Pyruvate is required to the mitochondria which then fully oxidized through the citric acid cycle. Aerobic cell respiration gives 36 ATP/glucose consumed.

Advantages of aerobic respiration:
Aerobic metabolism is 15 times more effective than anaerobic one because anaerobic gives 2 ATP molecules per one glucose molecule.
It generates a large amount of energy.
The aerobic respiration is the aerobic catabolism of various nutrients to carbon dioxide, water and energy. It involves an electron transport system and molecular oxygen acts as electron acceptor.
The overall reaction is:-
\[{C_6}{H_{12}}{O_6} + 6{O_2} \to 6C{O_2} + 6{H_2}O + ATP\,(Energy)\]

The correct answer is Carbon dioxide, water and energy.

Note:In aerobic respiration oxygen is required to break down amino acids, fatty acids and glucose. This is a method by which the body generates adenosine triphosphate (ATP) and it provides energy to the muscles.
