Biochem Exam 1 Questions and Answers Graded A+ What happens to enzymes when the temperature slightly increases within an optimal range? The enzyme activity increases as the kinetic energy of molecules rises, allowing more frequent collisions between enzyme and substrate. Why do hydrophobic amino acids tend to cluster together in the center of a protein? To avoid contact with water, stabilizing the protein's structure. What is the significance of the "lock and key" model...

Biochem Final Exam Questions and Answers with Verified Solutions How do prion proteins differ from traditional infectious agents? Prions are misfolded proteins that can induce misfolding in other proteins, leading to diseases without nucleic acids, unlike traditional pathogens. What is the purpose of the Krebs cycle in cellular respiration? The Krebs cycle generates electron carriers (NADH and FADH2) and ATP while oxidizing acetyl-CoA, contributing to energy production. How does ...
