Question

Cells take in small, energy-rich molecules from food. These molecules include sugar molecules. Cells use the molecules in a long series of chemical reactions. These reactions are known together as cellular respiration. Cellular respiration breaks down energy-rich molecules to form different molecules. This process also releases energy. Which of the following statements are true about cellular respiration? Select all that apply.
1.Cellular respiration occurs inside cells. 2.Cellular respiration releases energy. 3.Cellular respiration involves many chemical reactions.
4.Cellular respiration produces sugar molecules. ​

Answer 1

Answer:

1,2, and 3 are correct.

Explanation:

1 is true because cellular respiration begins in the cytoplasm of a cell. 2 is true because cellular respiration releases energy aerobically which uses glucose and oxygen or anaerobically which just uses glucose. Either way, energy is being released. 3 is true, I don't know how to explain why. Just keep the cellular respiration equation in mind, (C6H12O6 + 6O2 → 6CO2 + 6H2O + Chemical Energy (in ATP)), the chemical reactions are basically summed up into an equation. Hope that helped.
