The wood in a matchstick is made of cellulose, a polymer of glucose molecules. When you light the matchstick, heat and light are given off, indicating that an exothermic reaction is occurring.
There are two types of reactions:
1. Exothermic reactions: In these reactions, the reactants combine to form product and heat is liberated. Example, burning of fuel.
2.Endothermic reactions: In these reactions, the reactants combine to form product and heat gets absorbed from the surroundings. Example, photosynthesis in plants where the energy of the Sun gets absorbed.

Anyways, I hope this helps!
Answer:
Carbohydrate and mitochondria are closely connected with each because carbohydrate is a food substance from which energy is extracted by the mitochondria of the cell. Mitochondria is called the power house of the cell. Its main function is to make energy for the cell which used this energy to perform various function by using food material such as carbohydrate. So we can say that both are connected with each other.
Answer:
Mitochondria are double membrane bound cytoplasmic organelles present in most eukaryotic cells. They are responsible for aerobic respiration.
