Enzymes Flashcards
(10 cards)
Forms long chains that folds into specific shapes, creating the enzyme’s structure anad active site
Amino Acids
A specially shaped region where the substrate binds, allowing the enzyme to catalyze the reaction
Active Site
Inorganic ions like magnesium or iron that helps stabilize the enzyme-substrate complex.
Cofactors
Organic molecules, often from vitamins, that assist in transferring chemical groups during reaction
Coenzymes
The molecule that binds to the enzyme’s active site and is converted into a product
Substrate
Loss of electrons from a molecule, making it more positively charged
Oxidation
Gain of electrons by a molecule, making it more negatively charged
Reduction
How does pH affect enzymes activity?
Each enzyme has an optimal pH range where it works best. Deviations from its pH can change the enzyme’s shape or charged.
How does temperature affect enzyme activity?
Enzymes have optimal temperature where they function most effectively. Increasing temperature speeds up reaction, but if it gets too high, it can cause enzyme to denature, while low temperature slows down the reaction.
How does substrate concentration affect enzyme activity?
The reaction rate increases with more substrate until enzymes are saturated. After saturation, the rate stays constant as all active sites are in use.
