Question: Which of the following is a reason why respiration is considered an exothermic reaction?
- Respiration releases energy in the form of heat
- Respiration requires energy from food
- Both A and B
- None of the above
Answer: C. Both A and B
Why is Respiration Considered an Exothermic Reaction Explain the Solution:
Respiration is an exothermic reaction because it releases energy in the form of heat. This energy is used to power all of the activities of our cells, from building new molecules to transporting materials across membranes.
Respiration is considered an exothermic reaction because it releases energy. When living organisms undergo the process of respiration, they break down organic molecules, such as glucose, to produce energy in the form of adenosine triphosphate (ATP). This energy is essential for various cellular activities, allowing organisms to carry out functions like growth, repair, and movement.
During respiration, the chemical bonds in glucose are broken, and the released energy is harnessed by the cells.
Formula of Respiration
The formula of respiration describes the biochemical process through which cells convert nutrients into energy. It can be summarized by the equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
In this formula of respiration, glucose (C₆H₁₂O₆) reacts with oxygen (O₂) to produce carbon dioxide (CO₂), water (H₂O), and adenosine triphosphate (ATP), the energy currency of the cell. This process is essential for cellular energy production, enabling organisms to perform vital functions. Understanding the formula of respiration is crucial for studying cellular metabolism and energy dynamics in living organisms.
