Question

question 5: what happens to chemical energy during digestion?

Explanation:

During digestion, chemical energy stored in food molecules (such as carbohydrates, proteins, and fats) is released. This occurs through a series of chemical reactions. For example, in the breakdown of glucose (a carbohydrate), the bonds within the glucose molecule are broken. As these bonds break, energy is released. This energy is then used by the body for various functions like muscle contraction, nerve impulse transmission, and maintaining body temperature. The process is similar to how a fuel (like gasoline in a car) releases energy when it undergoes combustion (a chemical reaction). In the body, the chemical energy from food is converted into other forms of energy (such as mechanical energy for movement or thermal energy for heat) that the body can utilize.

Answer:

During digestion, chemical energy in food is released through chemical reactions and converted into forms of energy (like mechanical and thermal) that the body can use for its functions.
