2.1 STUDY NOTES: METABOLISM AND ENZYMES
METABOLISM OVERVIEW
Module Focus:
• Vocabulary of metabolism.
• Types of chemical reactions.
• Enzyme roles in facilitating reactions.
• Detailed study of ATP production.
De昀椀nitions:
• Metabolism encompasses all chemical reactions within a cell.
CATABOLIC AND ANABOLIC REACTIONS
• Catabolic Pathways: [remember ‘catastrophic’ = breakdown]
• Break down larger molecules into smaller ones (monomers).
• Generate energy crucial for cellular functions.
• Anabolic Pathways:
• Build complex molecules using energy.
• Importance:
• Both pathways are vital for cell survival.
• Tightly regulated to conserve nutrients and energy.
ENZYMES
• Enzyme = Protein
