Study Notes
Energy and Its Importance
- Energy is defined as the ability to do work, crucial for all life processes.
Thermodynamics
- Thermodynamics explores the flow and transformation of energy in the universe.
- First Law: The law of conservation of energy; energy cannot be created or destroyed, only transformed.
- Second Law: Energy transformations are not 100% efficient; some energy is always lost in the process.
Metabolism
- Metabolism encompasses all chemical reactions occurring within a cell, vital for maintaining life.
Photosynthesis
- Photosynthesis is the process where plants convert light energy into chemical energy, using sunlight to produce glucose.
Cellular Respiration
- Cellular Respiration is a catabolic pathway where organic molecules are broken down to release energy for cellular functions.
Adenosine Triphosphate (ATP)
- Adenosine Triphosphate (ATP) is the primary biological molecule providing chemical energy for cells, essential for energy transfer.
Chemoautotrophs
- Chemoautotrophs are organisms that synthesize their food using inorganic substances, playing a key role in certain ecosystems.
Metabolic Pathways
- Metabolic Pathway refers to a sequence of biochemical reactions, where the product of one reaction serves as the reactant in the next.
Major Energy Source
- The major source of energy for living organisms is the Sun, which drives photosynthesis, the foundation of the food chain.
Anabolic vs. Catabolic Pathways
- Catabolic Pathways: Break down larger molecules into smaller ones, releasing energy.
- Anabolic Pathways: Use the energy released by catabolic pathways to synthesize larger molecules.
- Both types of pathways contribute to a continuous flow of energy throughout the organism.
