Question

chambers a and b are placed next to each other but are separated by a film permeable to both glucose and fructose. chamber a contains 80% glucose and 60% fructose and chamber b contains 20% glucose and 40% fructose. which of the following will occur? multiple choice glucose and fructose will move into chamber a at the same rate. fructose will move into chamber a faster than glucose. glucose and fructose will move into chamber b at the same rate. fructose will move into chamber b faster than glucose. glucose will move into chamber b faster than fructose.

Explanation:

1. First, analyze the concentration gradients for glucose and fructose:

• For glucose: Chamber A has 80% and Chamber B has 20%, so glucose will move from A to B (down its concentration gradient).
• For fructose: Chamber A has 60% and Chamber B has 40%, so fructose will move from A to B (down its concentration gradient).

1. Now, consider the rate of diffusion. The rate of diffusion of a solute across a permeable membrane depends on the magnitude of the concentration gradient (and also the molecular size, but glucose and fructose are both monosaccharides with similar molecular weights/sizes).

• The concentration gradient for glucose is \( 80\% - 20\%=60\% \) (difference in concentration between A and B).
• The concentration gradient for fructose is \( 60\% - 40\% = 20\% \) (difference in concentration between A and B).
• Since the concentration gradient for glucose is steeper (larger difference) than that for fructose, glucose will diffuse (move) into chamber B faster than fructose.

Answer:

The correct option is: Glucose will move into chamber B faster than fructose. (The option with the text "Glucose will move into chamber B faster than fructose" among the given choices)
