Question

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

respiration in the fish?

The total number of carbon atoms decreases because the carbon-containing
molecules from the food are destroyed during digestion.

The total number of carbon atoms increases because the carbon-containing
molecules from the food are used to make smaller carbon dioxide molecules.

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.

The total number of carbon atoms decreases because the carbon from the carbon-containing food molecules changes into other types of atoms.

PLEASE HELP ASAP

Answer 1

The total number of carbon atoms remains the same during cellular respiration, as they are reorganized into carbon dioxide, conforming to the law of conservation of mass.

Step-by-step explanation:

The statement that 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. This reflects the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only transformed. During cellular respiration, the carbon atoms from glucose or other carbohydrates are broken down and reorganized, eventually forming carbon dioxide which is then exhaled.

Answer 2

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

Step-by-step 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
