Exothermic Process
Respiration is an exothermic process, meaning it releases energy in the form of heat. This process involves breaking down glucose molecules to produce ATP (adenosine triphosphate), the main energy currency of cells. Below are the key points explaining why respiration is an exothermic process:

Energy Release:
During respiration, glucose is oxidized in a series of biochemical reactions that release energy stored in its chemical bonds. This energy is used to produce ATP, which powers various cellular activities.

Heat Production:
As glucose is broken down, energy is released in the form of heat. This heat contributes to maintaining the body temperature of organisms, especially in endothermic animals that regulate their internal temperature.

Thermodynamically Favorable:
The overall process of cellular respiration is exergonic, meaning it releases more energy than it consumes. This makes it thermodynamically favorable and an exothermic process.

Comparison to Endothermic Processes:
In contrast to endothermic processes that absorb heat from the surroundings, respiration gives off heat to the environment. This heat release is crucial for sustaining metabolic activities and maintaining homeostasis in living organisms.
In conclusion, respiration is an exothermic process due to the release of energy in the form of heat during the breakdown of glucose molecules. This energy is essential for cellular functions and overall metabolism in organisms.

Respiration is called as exothermic process (heat is released during exothermic process) as heat is a form of energy and in respiration energy is released in the form of ATP...
