Life Processes Cheat Sheet

Key Definitions

• Metabolism: The sum of all chemical reactions in an organism. ✅

• Photosynthesis: Process by which plants convert light energy into chemical energy. ✅

• Respiration: The process of breaking down glucose to release energy. ✅

• Homeostasis: The maintenance of a stable internal environment. ✅

Important Concepts

Metabolism

• Anabolism: Building up molecules (e.g., protein synthesis). ✅

• Catabolism: Breaking down molecules (e.g., cellular respiration). ✅

Photosynthesis

• Equation: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2 ✅

• Occurs in chloroplasts of plant cells. ✅

Respiration

• Aerobic Respiration: Requires oxygen; produces more energy. ✅

• Anaerobic Respiration: Occurs without oxygen; less energy produced. ✅

Key Formulas

• Photosynthesis: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2 ✅

• Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy ✅

Common Mistakes to Avoid

Common Mistake: Confusing photosynthesis with respiration; they are opposite processes.
