  • What is the lock and key model of enzyme action?

    What is the lock and key model of enzyme action?

    The lock and key model suggests that the enzyme’s active site is specifically shaped to fit the substrate, like a…

  • What factors affect enzyme activity?

    What factors affect enzyme activity?

    Factors that affect enzyme activity include temperature, pH, enzyme concentration, and substrate concentration.

  • What is an active site?

    What is an active site?

    The active site is the region on an enzyme where the substrate binds and where the chemical reaction takes place.

  • Define substrate.

    Define substrate.

    A substrate is the molecule upon which an enzyme acts to catalyze a chemical reaction.

  • What is enzyme specificity?

    What is enzyme specificity?

    Enzyme specificity refers to the ability of an enzyme to catalyze a particular reaction for a specific substrate.

  • Define coenzymes.

    Define coenzymes.

    Coenzymes are small organic molecules that assist enzymes in their catalytic activity, often by transferring chemical groups.

  • How do temperature and pH affect enzyme activity?

    How do temperature and pH affect enzyme activity?

    Enzyme activity increases with temperature until a certain point, after which the enzyme may denature. Extreme pH levels can also…

  • What is enzyme inhibition?

    What is enzyme inhibition?

    Enzyme inhibition occurs when a molecule binds to an enzyme and reduces its activity, either competitively or non-competitively.

  • Explain the mechanism of enzyme action.

    Explain the mechanism of enzyme action.

    Enzymes speed up reactions by lowering the activation energy. The substrate binds to the enzyme’s active site, forming an enzyme-substrate…

  • Discuss the types of enzyme inhibition.

    Discuss the types of enzyme inhibition.

    Enzyme inhibition can be: Competitive Inhibition: Involves an inhibitor that competes with the substrate for binding to the active site….
