Answer 1

Answer:

2. Respiration is a chemical reaction.

(a) Where does it take place?

(c) Why is it important for living cells?

(b) What type of chemical reaction is it?

Explanation:

Respiration releases chemical energy stored in sugars, making it an exothermic reaction. Organisms use that energy to live. It originally comes from solar energy, which is converted into chemical energy during photosynthesis.Respiration is a chemical change as new substances like carbon dioxide and water are formed. Also there is change in the mass as glucose is oxidised by oxygen and heat is released. This change is permanent. All these factors conclude that respiration is a chemical change.Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water
