Enzyme Inhibits Plots
Allosteric regulation of enzyme activity Allostery: Key Point Binding of a ligand at a site different from the active site modulates the activity. This.
ENZYMES SBI4U0. ENZYMES An enzyme is a biological catalyst –Biological = protein –Catalyst = speeds up a reaction without being consumed or permanently.
Chapter 1 - Introduction to Cells
Review Enzymes are specific to a substrate Based on shape (lock & key) Enzymes are NOT consumed or changed by catalyzed reaction Great for speeding up.
How are enzymes regulated? By controlling their concentration –Control of synthesis (activation or repression) –Degradation By controlling the availability.
CELL METABOLISM Enzymes Definition Catalysts Proteins that speed up chemical reactions by lowering the energy of activation.
Enzymes Protein molecules that act as catalysts. Catalysts Speed up the rate of reactions Are not permanently changed or used up Reactants: what.
Regulation of Enzyme Activity Enzyme activity must be regulated so that the proper levels of products are produced at all times and places This control.
