Life is a characteristic that distinguishes physical entities that have biological processes, such as growth, reproduction, and response to stimuli, from those that do not. It is a complex and dynamic process that involves various biochemical reactions and interactions within an organism.

Metabolism, on the other hand, refers to the set of chemical reactions that occur within an organism to maintain life. These reactions involve the conversion of nutrients into energy and building blocks for growth, repair, and maintenance of cells and tissues. Metabolism is essential for the survival and functioning of all living organisms, as it provides the energy and resources needed for various biological processes.

Life

- A complex and highly organized state of matter that includes the ability to reproduce, grow, and respond to environmental stimuli.
- A set of processes and interactions that maintain the existence of an organism.
- A spectrum of characteristics that distinguish living organisms from non-living matter.

Metabolism

- The sum of all chemical reactions that occur within a living organism, including:
- Catabolism: Breaking down complex molecules into simpler ones, releasing energy.
- Anabolism: Building complex molecules from simpler ones, requiring energy.
- Essential for maintaining homeostasis, growth, and reproduction.
- Involves the exchange of energy and matter with the environment.

Interrelationship of Life and Metabolism

- Metabolism is the foundation of life, providing the energy and building blocks necessary for its functions.
- The specific metabolic pathways that an organism employs reflect its adaptation to its environment.
- Metabolism contributes to the unique characteristics of life, such as:
- Reproduction: Providing the energy and molecules needed for cell division.
- Growth: Synthesizing new molecules for tissue expansion.
- Homeostasis: Regulating internal conditions to maintain optimal function.
- Adaptation: Allowing organisms to adjust their metabolism to environmental changes.

Examples of Metabolism

- Photosynthesis: Converting light energy into chemical energy, producing glucose.
- Cellular respiration: Breaking down glucose to release energy for cell activities.
- Protein synthesis: Assembling amino acids to build new proteins.
- Lipid metabolism: Storing and utilizing fats for energy.
