Enzymes – Biochemistry Questions and Answers with Verified Solutions What is the primary function of enzymes in biological systems? Enzymes act as catalysts, speeding up chemical reactions without being consumed in the process. How do temperature and pH affect enzyme activity? Enzymes have optimal temperature and pH ranges where they function best; deviations can lead to reduced activity or denaturation. What is the active site of an enzyme? The active site is the specific re...

2024 MICR 290 MIDTERM EXAM /ACTUAL EXAM WITH CORRECT DETAILED ANSWERS - WEST COAST UNIVERSITY, LATEST UPDATE A+ GRADE 1. Define metabolism, catabolism, and anabolism. What is the role of ATP in catabolism and anabolism? - Metabolism : Chemical process that occurs within a living organism in order to maintain life - Catabolism : The breakdown of complex organic compounds into simpler ones (the energy-releasing processes) - Role of ATP : ATP Synthesis - Anabolism : Building of complex orga...

What is kcat? What is a holoenzyme? Correct Answer-Kcat=overall rate of an enzyme, catalytic efficiencies. Holoenzyme (active) is an inactive apoenzyme with non-protein components. (look at the picture) Discuss enzyme-substrate specificity. What is the lock and key vs. induced fit model? Correct Answer-Induced fit: enzyme changes after substrate binds to make it fit more perfectly. Discuss energy implications of enzymes. Does it change the activation energy or free energy of the overal...

Intro to Enzymes correct answers - a requirement for life is the ability to efficiently and selectively catalyze chemical reactions - most biomolecules are very stable and the uncatalyzed transformations would be too slow to permit life - experiments done showed that dead yeast could still convert sugars into alcohol indicated that the reactions of life could be separated from life - there was a factor in yeast catalyzing the reaction vitalism correct answers a belief that originally, bioc...
