Question

Which statement best describes the total number of carbon atoms during cellular

Answer 1

Answer:

statement best describes the total number of carbon atoms during cellular

respiration in the fish is :

The total number of carbon atoms stays the same because the carbon from the carbon-containing food molecules is used to make molecules such as  carbon dioxide

Explanation:

Respiration : It is a process in which energy from the "food" molecule is released in the form of ATP

ATP = Adenosine Triphosphate

There are two kind of respiration process:

1. In the presence of O2 = Aerobic  Oxidation

2. In the absence of O2 = Anaerobic Oxidation

The breakdown of food into CO2 occur by three main process:

Glycolysis

Krebs cycle

Phosphorylation

The reaction for the Decomposition of the Glucose molecule is written as:

$C_{6}H_{12}O_{6}+O_{2}\rightarrow 6CO_{2}+6H_{2}O+ATP$

It is a oxidation - reduction reaction(Redox).

Here one substance is oxidised and other is reduced.

The number of Carbon atoms in reactant =6

It will produce = 6 CO2 in which the number of C=6

Hence ,

The total number of carbon atoms stays the same because the carbon from the carbon-containing food molecules is used to make molecules such as  carbon dioxide
