← ScienceWhich risk increases when flash-freezing biological samples transitions too slowly?
A)Extracellular ice crystal formation expands✓
B)Intracellular vitrification inhibits enzymes
C)Molecular vibration decreases entropy
D)Metabolic rate decreases exponentially
💡 Explanation
Extracellular ice crystal formation expands because slow phase transitions favor the gradual growth of ice crystals in the extracellular medium rather than rapid intracellular vitrification; therefore, larger extracellular crystals risk damaging cellular structures rather than vitrifying intracellular contents.
