VERIFIED SOLUTIONS FULL CONTENT
◉ Low Km means
Answer: High substrate affinity
◉ High Km means
Answer: Low substrate affinity
◉ Competitive inhibition
Answer: Increases Km but does not change Vmax
◉ Noncompetitive inhibition
Answer: Decreases Vmax while Km stays approximately the same
◉ Competitive inhibitors
Answer: Can usually be overcome with more substrate
◉ Noncompetitive inhibitors
Answer: Cannot be overcome by increasing substrate concentration
, ◉ Vmax
Answer: Maximum reaction rate when enzymes are saturated
◉ Km
Answer: Substrate concentration at half Vmax
◉ Enzymes lower
Answer: Activation energy
◉ High temperatures can denature enzymes by disrupting
Answer: Hydrogen bonds and ionic interactions
◉ Extreme pH affects enzymes by
Answer: Altering ionization states and disrupting protein structure
◉ Primary protein structure
Answer: Amino acid sequence connected by peptide bonds
◉ Secondary protein structure
Answer: Alpha helices and beta sheets stabilized mainly by
hydrogen bonds
