In which of the following processes is energy released?a)Respirationb)Photosynthesisc)Ingestiond)AbsorptionCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Respiration:
- Respiration is a process in which energy is released from glucose molecules to produce ATP (adenosine triphosphate), the energy currency of cells.
- During respiration, glucose is broken down into carbon dioxide and water, releasing energy in the form of ATP.
- This energy is used by cells for various metabolic activities and processes essential for life.
- Respiration occurs in the mitochondria of cells and is a fundamental process for the survival of organisms.

Photosynthesis:
- Photosynthesis is a process in which energy from sunlight is used to convert carbon dioxide and water into glucose and oxygen.
- This process requires energy input, rather than releasing energy like respiration.
- Plants and other autotrophic organisms carry out photosynthesis to produce food for themselves and other organisms.

Ingestion and Absorption:
- Ingestion is the process of taking in food, while absorption is the process of absorbing nutrients from food into the bloodstream.
- These processes do not directly release energy but rather provide the necessary nutrients for energy production through respiration.
In conclusion, respiration is the process in which energy is released from glucose molecules, making it the correct answer to the question.
