Which statements accurately describe how fructose metabolism in the liver differs from glucose metabolism?
a. the fructose 1‑phosphate pathway can deplete intracellular phosphate/ atp .
b. in fructose metabolism, the phosphofructokinase reaction is bypassed and glycolysis can proceed regardless of need.
c. the presence of fructose inhibits the entrance of glucose into glycolysis.
d. the major control point in both glucose and fructose metabolism is the reaction catalyzed by phosphofructokinase.

The fructose 1-phosphate pathway can deplete intracellular phosphate/ ATP.

Explanation:

Fructose 1-phosphate is a derivative of fructose. For understanding in better way fructose metabolism has three enzymes. Fructose- bisphosphate aldolase B, fructokinase and Adenosine triphosphate. These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase.

After it is converted into trioses dihydroxyacetone phosphate as well as glyceraldehyde through aldolase.  With glucose metabolism Fructose get synergistic effect

Answer : The correct option is, D

Explanation :

Saturated solution : It is a chemical solution which contain the maximum amount of solute dissolved in the solvent. In saturated solution, the additional amount of solute will not dissolve in the solvent.

When a student has a solution of sodium nitrate then we can check their saturation point by adding additional amount of sodium nitrate. When we add more amount of sodium nitrate in the solution, then all of it will settle down to the bottom of the container.

Therefore, the best evidence for saturated solution is, When additional sodium nitrate is added, it all settles to the bottom of the container.
