Question

Cellular respiration describes the process that living cells use to release energy by combining sugar and oxygen. The primary chemical changes that happen during cellular respiration are shown in the equation below. Which statement correctly compares the reactants and products of the equation? A. The mass of the reactants is the same as the mass of the products. B. The number of reactant atoms is greater than the number of product atoms. C. The mass of the reactants is less than the mass of the products. D. The number of reactant atoms is less than the number of product atoms.

Answer 1

Option A- The equations always have to be balanced.

Step-by-step explanation:

Answer 2

The equation is missing in the question, so he given equation is:

C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP

Answer: The correct answer is option A.

Explanation:

The mass of reactant is always equal to mass of the product because the equation has to be balanced.

The reactant for cellular respiration is carbohydrates and in the presence of oxygen it is being converted into carbon dioxide and water.

The mass of reactant will always have to equal to mass of product. The energy stored in the carbohydrates is converted into adenosine tri phosphate.
