The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl), and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same. Refer to the figure to answer the following questions.

At the beginning of the experiment,

A) side A is hypertonic to side B.

B) side A is hypotonic to side B.
C) side A is hypertonic to side B with respect to glucose.
D) side A is hypotonic to side B with respect to sodium chloride.

E) side A is isotonic to side B.

Answer:
B) side A is hypotonic to side B.

    A) Succinate dehydrogenase is the enzyme, and malonic acid is the substrate.

    B) Malonic acid is the product, and fumarate is a competitive inhibitor. C) Succinate dehydrogenase is the enzyme, and fumarate is the substrate.

    D) Succinate is the substrate, and fumarate is the product.

    E) Fumarate is the product, and malonic acid is a noncompetitive inhibitor.

    D) Succinate is the substrate, and fumarate is the product.
