Key Area 6: Metabolic Pathways KA 6: Metabolic Pathways (E) Control of metabolic pathways through inhibitors (A) Metabolism (B) Control of metabolic pathways through enzymes (C) Induced fit and Active sites (D) Effect of substrate and end-product concentrations

Metabolic Pathways (a) Revise your knowledge on the properties of enzymes State what is meant by metabolism and metabolic pathway State what is meant by an anabolic pathway (and make reference to energy) State what is meant by a biosynthetic reaction State what is meant by an catabolic pathway (and make reference to energy) Give an example of an anabolic and catabolic reaction

What do all these words mean? Key Words Anabolism Induced Fit Catabolism Degradation Biosynthetic Synthesis Enzyme Amylase Metabolism Catalase Substrate Active site Activation energy Specificity TASK: Think / Pair / Share What do all these words mean?
