Question

The correct equation of aerobic respiration is
(a) $C_{6}H_{8}O\rightarrow 6CO_{2}+4H_{2}O$
(b) $C_{6}H_{12}O_{6} + 6O_{2}\rightarrow 6CO_{2} +6H_{2}O$
(c) $C_{6}H_{12}O_{6} + 6O_{2} + 6H_{2}O\rightarrow 6CO_{2} + 12H_{2}O$
(d) $C_2H_{5}OH + 3O_{2}\rightarrow 2CO_{3} + 3H_{2}O$

Answer 1

Hint: This is a process depicted by the entire living organisms, and it ensures their survival. Most of the aerobic respiration occurs in the mitochondrion in most of the plants and animals.

Complete answer:
The correct equation for aerobic respiration is:
$C_{6}H_{12}O_{6} + 6O_{2}\rightarrow 6CO_{2} + 6H_{2}O +ATP$
Respiration is a catabolic- physicochemical process, which involves the exchange of environmental oxygen and body carbon dioxide through a liquid medium. After this, the oxidation of glucose inside the mitochondria produces energy, which is partly stored in the high energy bonds of ATP (Adenosine Triphosphate) molecules. The ATP is used as biologically useful energy.
- The nutrient, which provides energy by its oxidation inside the body, is called respiratory fuel.
- The main respiratory fuel in our body is glucose, it is present abundantly in the body fluids.
- The physiological value of glucose is 4 Kcal.
- The fats are concentrated fuel with a physiological value of 9 Kcal.
- Fats are used as respiratory fuel after their hydrolysis to fatty acids and glycerol by lipase enzyme and their subsequent conversion to hexose sugar.
- Proteins serve as a respiratory fuel after their breakdown of amino acids. By proteolytic enzymes.
- Protoplasmic respiration is the term used when proteins are used as respiratory fuels.
- When carbohydrates or fats are used as respiratory fuel, then it is called as floating respiration.
So, the correct answer is, ‘$C_{6}H_{12}O_{6} + 6O_{2}\rightarrow 6CO_{2} + 6H_{2}O$.’

Note: The released energy during the process of respiration may not be required immediately and the site of endergonic processes may be away from the site of exergonic processes. ATP provides a quick source of energy when required, so the ATP is commonly called as energy currency.
