nmdcat.online July 11, 2026

Regarding the influence of temperature, enzymes from cold-water organisms usually possess

A. Higher optimum temperatures than thermophilic enzymes
B. Lower optimum temperatures than mammalian enzymes
✓
C. The same optimum temperature as bacterial enzymes
D. No temperature dependence

📝 Explanation

Cold-adapted enzymes function efficiently at low environmental temperatures and are less stable at higher temperatures.

📖 Additional Information

  • Higher optimum temperatures than thermophilic enzymes
  • Lower optimum temperatures than mammalian enzymes
