Step-by-step explanation:
Exothermic reaction are those reaction in which energy is released as a product. The temperature of the surrounding increases.
Exothermic reaction are those reaction in which energy is absorbed by the reactants . The temperature of the surrounding decreases.
A) In process-2 , glucose molecule is broken down into water and carbon dioxide along with the release of an energy. This reaction is an example of exothermic reaction.
B) In process-3,4, glucose molecule is broken down into respective product along with release of energy.
C) Process -1 ,2.
Process-1 chemical representation of photosynthesis process found in plants .
Process-2 chemical representation of cellular respiration are found in plants cells.
D) Process-2,3.
The process -2 is a chemical representation of cellular respiration and process -3 is a chemical representation of anaerobic cellular respiration(takes place in the absence of oxygen).
