Which of the following Processes is Exothermic?

  • 1.Photosynthesis
  • 2.Melting of ice
  • 3.Respiration
  • 4.Transpiration
Correct Answer
Option 3:Respiration

The process of respiration is exothermic. When heat is produced during a reaction, a process is exothermic. Examples of exothermic reactions include combustion, the nuclear fission of uranium-235, the detonation of nitroglycerin, neutralization reactions, respiration, etc.

Process of Respiration

The process by which people inhale oxygen and exhale carbon dioxide is known as respiration. Because of the oxidation of glucose that occurs during respiration, which results in a significant quantity of heat energy produced and stored in the form of ATP, respiration is regarded as an exothermic reaction.

  • Green plants use the process of photosynthesis to convert carbon dioxide and water into food with the help of solar energy.
  • Water is lost from the aerial regions of plants in the form of water vapor through a biological process called transpiration.
  • Living things release energy through the process of respiration, which involves taking in oxygen and exhaling carbon dioxide.

Thus, it follows that respiration is a significant and essential gas exchange mechanism. The blood cells transport the gases involved in respiration, including oxygen and carbon dioxide.
