Item EB025002: The amount of energy required to separate atoms of the reactants of cellular respiration is less than the amount of energy released as atoms connect to form products.
Cellular respiration is a chemical reaction that occurs in plants and animals. As the atoms that make up the reactant molecules of cellular respiration are separated, is energy required or released? How does that amount of energy compare to the energy associated with forming the product molecules?
- Energy is required to separate atoms of the reactants. This amount of energy is less than the amount of energy released as atoms connect to form the products.
- Energy is required to separate atoms of the reactants. This amount of energy is greater than the amount of energy released as atoms connect to form the products.
- Energy is released as atoms of the reactants are separated. This amount of energy is greater than the amount of energy required to connect the atoms to form the products.
- Energy is released as atoms of the reactants are separated. This amount of energy is less than the amount of energy required to connect the atoms to form the products.
