Unit 3: Cellular Energetics

Key Concepts:

• Enzyme structure, specificity, and the role of the active site

• Factors affecting enzyme activity (temperature, pH, substrate concentration)

• Enzyme regulation (competitive vs. noncompetitive inhibitors)

• Cellular respiration: glycolysis, Krebs cycle, oxidative phosphorylation

• Photosynthesis: light-dependent reactions and the Calvin cycle

• Energy transfer and ATP production in metabolic pathways
