Question

The breaking down of food to carbon dioxide and water is a type of -

(a) Endothermic reaction

(b) Thermit reaction

(c) Exothermic reaction

(d) Reaction without energy change​

Answer 1

Explanation:

The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen. ... Breakdown of food releases energy.

Answer 2

It is an exothermic reaction. (option c)

• The release of heat during a chemical reaction is said to be an exothermic reaction.
• There is the release of energy in the form of heat.
• When the food breaks down to carbon dioxide and water, there is the release of energy. Therefore it is said to be an exothermic reaction.
• This process is called cellular respiration and this process occurs in the cells of the organism.
