Cheat Sheet
- Enzyme Specificity: Lock-and-Key vs. Induced Fit -
Enzymes show remarkable specificity in which best describes how enzymes function in the body by binding substrates through either a rigid "lock-and-key" model or a flexible "induced fit," ensuring precise catalysis (Source: NCBI Bookshelf). A handy mnemonic is "Lock before you knock" to recall the lock-and-key concept while the induced fit adapts like a glove (Source: University of Oxford Biochemistry).
- Michaelis-Menten Kinetics and Key Parameters -
Understanding how do enzymes work means mastering the Michaelis-Menten equation: v = (Vmax [S])/(Km + [S]), where Km reflects substrate affinity and Vmax shows maximum rate (Source: Lehninger Principles of Biochemistry). Remember that a low Km indicates high affinity - as in hexokinase's tight grip on glucose - helpful for enzyme activity questions on your GCSE enzymes quiz.
- Temperature, pH, and Substrate Concentration Effects -
Enzyme activity in the human body peaks at optimum temperature and pH, creating a bell-shaped activity curve; deviations denature the protein or change ionization (Source: Khan Academy Biochemistry). Boost your recall with "Happy pH makes enzymes slay," and note that increasing substrate concentration raises rate until Vmax is reached.
- Competitive vs. Noncompetitive Inhibition Techniques -
Competitive inhibitors compete for the active site, raising Km but leaving Vmax unchanged, whereas noncompetitive inhibitors bind allosterically to reduce Vmax without affecting Km (Source: Nature Reviews Molecular Cell Biology). Use the phrase "COMPete for the seat; NON-coop blocks the party" to ace enzyme inhibition questions.
- Vital Roles in Digestion, Metabolism, and Cofactors -
Enzyme function in the human body spans digestive enzymes like amylase and pepsin to metabolic champions such as ATP synthase; many need cofactors like Mg2+ or coenzymes like vitamin B (Source: University of California, Berkeley).
