Metabolism Flashcards
Anabolic Reaction
Build up of large molecules from smaller molecules
Catabolic Reaction
Break down of Larger molecules into smaller molecules
Enzymes
3D protiens that have active sites
Activation Energy
Energy needed to start a chemical reaction
Catabolic Enzymes
Weakening of chemical bonds, substrate breaking into smaller products
Anabolic Enzymes
Forms Chemical bonds, substrate forming into larger products
Cofactors and Coenzymes
Small non-protien molecules vital for enzyme function
Inhibitors
Molecules that interfere with the enzyme in some way
Competitive Inhibitor
Similar shape to the substrate and prevents substrates binding to active site
Non-Competitive inhibitor
Binds to enzyme (Not AS) and changes shape of enzyme, prevents product complex from forming
Factors affecting enzyme activity
Temperature, pH, Enzyme concentration, Co-factors
Affects of high temperatures
Active site denatures, chemical bonds break and no products formed
Affects of wrong PH
Enzymes are denatured by pH
Enzyme Concentration
Rate of reaction increases, assuming sufficient substrate
Substrate Concentration
Increases reaction rate initially, but active site becomes saturated
