Cards in this deck (20)
- 1EnzymesBiological catalysts that Increase the rate of a reaction while decreasing the activation energy required
- 2Induced FitMechanism where an enzyme binds with a substrate, not exactly complementary and changes its shape to produce an exact fit
- 3Extracellular EnzymesEnzymes that work outside of the cell that affect digestive reactions
- 4Activation EnergyThe energy required to start a chemical reaction. Reduced by enzymes
- 5Enzyme Substrate ComplexFormed when the substrate binds to the enzyme with weak chemical bonds
- 6Metabolic ReactionsReactions that are controlled by enzymes and take place within cells
- 7InactivatedThe state of the enzyme when it is below its optimal temperature / below and above its optimal pH
- 8DenatureWhen the tertiary structure of an enzyme (protein) changes therefore changing its biochemcial properties
- 9Lock and KeyMechanism used to explain the binding of enzymes where the substrate is simply drawn into the matching cleft and fits perfectly
- 10RibosomesSites of protein, therefore enzyme, synthesis
- 11CofactorsInorganic chemical substances that help the enzyme increase the rate of reaction. Reusable
- 12CoenzymesOrganic molecules that help the enzyme catalyse reactions. Used up in a reaction and need to be constantly replaced before another reaction can take place
- 13IntracellularEnzymes used inside the cell. Usually used in metabolism
- 14CatalystsSubstances that increase the rate of reaction without being used in the process
- 15Saturationthe point at which all the active sites of the enzymes are occupied as there is a surplus or high concentration of substrate
- 16VitaminsCo-enzymes as they are organic
- 17Catabolicreactions that release energy after breaking bonds in polymers or large molecules into smaller parts, sub units or monomers
- 18Limiting FactorCheck: To Do
- 19Feedback InhibitionWhen the last product of a metabolic pathway (sequence) that becomes an inhibitor and it binds to the first enzyme of the metabolic pathway and it temporarily stops the metabolic pathway until all the final products have been used up
- 20Catalytic CycleA reaction that involves a catalyst
