Quick Answer
The Class 9 Biology Chapter 7 Notes FBISE cover the core topics of Metabolism based on the new NBF textbook. It includes step-by-step solutions to textbook exercises, solved MCQs, short questions, and long questions. Key concepts include metabolism types, enzyme characteristics & activation energy, factors affecting enzyme activity (temperature, pH, substrate concentration), enzyme inhibition, ATP role & cycle, photosynthesis light dependent & independent reactions, limiting factors, anaerobic/aerobic respiration mechanisms (Glycolysis, Krebs Cycle, ETC). These SLO-based notes are fully optimized for student preparation for the 2026-2027 annual exams.
Chapter Overview
Chapter 7 explores the metabolic processes that power living organisms. It defines metabolism (anabolism and catabolism) and details enzyme characteristics, mechanisms of action, and factors affecting activity (temperature, pH, substrate concentration). Competitive and non-competitive enzyme inhibition are also discussed.
The chapter covers cellular energetics, outlining the structure of ATP (High Energy Bonds) and the ATP-ADP Cycle. It covers photosynthesis, covering both light-dependent and light-independent reactions, alongside limiting factors that govern rate.
Lastly, the chapter details cellular respiration, contrasting aerobic respiration (detailing Glycolysis, formation of Acetyl CoA, Krebs Cycle, and the Electron Transport Chain) with anaerobic respiration (its types and importance). Solved questions and MCQs align with the FBISE SLO guidelines.
