BIOS 101 Lecture Notes - Lecture 10: Exergonic Reaction, Deoxyribonuclease, Catalytic Cycle
Document Summary
Organic catalysts which increase rate of biochemical reactions in cells: example i. ii. iii. iv. v. Glucose, fructose = products: enzyme often named for substrate by adding suffix ase . Synthesized on ribosomes form instructions in dna: not all types contain same enzymes f. In exergonic reactions, enzyme speed up reactions by lowering amount of e reactants must absorb to start reactions= activation e i. Enzyme do not add e to reactions: how enzymes catalyze exergonic biochemical reaction, general steps in the catalytic cycle of an enzyme i. ii. iii. iv. v. vi. vii. viii. The enzyme and substrate must collide to start the reaction. The substrate momentarily binds to the active site of the enzyme. An active site is a pocket on the surface of an enzyme resulting from 3-d folding of the enzyme. The active site is where the enzyme binds and catalysis occurs.
