Answer:
Prediction results for glucose transport in the presence of Dinitrophenol (DNP) are as following:
- Decreased transport of glucose
- DNP disrupts the gradient of protons and the output of ATP
- ATP needed for the Na+/K+ pump to the est. Gradient Na+
- The gradient required for Sodium-glucose cotransporters (SGLTs)
Dinitrophenol (DNP) is an uncoupler, or is capable of separating electron flow and H+ ion pumping for ATP synthesis. This means that ATP synthesis can not use the energy from electron transfer, hence it will support in lab as well.
Answer:
Taking into account the principle of osmosis, the question that best addresses experimental design is <em>How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?</em>
Explanation:
The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.
Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.
The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.
How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?
The experiment shows that:
- The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
- Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.
With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.

2. detritivores are decomposes because they consume other material to break it down.
3. need to see the image on p.591 to answer but a producer is a type of plant that supplies energy to a first level consumer, a detritivore would be a type of fungi that is pictured because fungi break down materials.
