Question

When the water inside a living cell freezes, the ice crystals damage the cell. The wood frog is a unique creature that can survive being frozen. In extremely cold

conditions, the frogs liver produces large amounts of glucose (C6H12O6), which becomes concentrated in the frog's cells. How does the glucose help prevent ice

from forming in the frogs cells?

A)The added glucose dissociates and creates faster moving molecules.

B) The added glucose lowers the vapor pressure relative to the pure solvent.

C) The added glucose requires more energy which warms the frog

D)The added glucose lowers the freezing point of the solution within the frog's cells.

Answer 1

The wood frog's cellular glucose concentrations increase to prevent ice formation by lowering the freezing point of the intracellular fluid, effectively inhibiting the growth of ice crystals within the cells.

Step-by-step explanation:

When the wood frog's liver produces large amounts of glucose in response to extremely cold conditions, the glucose accumulates in the frog's cells. This adaptation helps prevent ice from forming inside the cells by lowering the freezing point of the intracellular fluid. The glucose molecules interfere with the formation of the ice lattice because they cannot be incorporated into the lattice structure, hence decreasing the rate of freezing.

As a result, the temperature needs to be lowered further for the dynamic equilibrium between solid and liquid water to reestablish, meaning that freezing within the frog's cells is less likely to occur at the same temperatures that would normally cause water to freeze.

Answer 2

but i think its B but i need answer too
