Question

The diagram shows the reactants and products involved in cellular respiration. Which statements correctly describe cellular respiration? Check all that apply.

1) Energy is a reactant.
2) Energy is a product.
3) The reaction is endothermic.
4) The reaction is exothermic.
5) Sugar reacts with oxygen.
6) Sugar reacts with carbon dioxide.

Answer 1

Cellular respiration is a process that converts glucose and oxygen into carbon dioxide, water, and ATP. Energy is produced as a product of cellular respiration. The reaction is exothermic.

Step-by-step explanation:

Cellular respiration is a process that converts glucose and oxygen into carbon dioxide, water, and ATP. Therefore, statement 1 is false because energy is not a reactant but rather a product of cellular respiration. Statement 2 is true because ATP is produced as a result of cellular respiration.

Statement 3 is false because the reaction is exothermic, meaning it releases energy. Statement 4 is true because exothermic reactions release energy. Statement 5 is true because glucose reacts with oxygen to produce carbon dioxide and water. Statement 6 is false because sugar does not react directly with carbon dioxide in cellular respiration.
