How can dissolved materials be moved from the outside to the inside of a cell when the inside concentration of the material is higher than the outside concentration?
a. Molecules can be moved into a cell against their concentration gradient if that transport is coupled with osmotic transport of water into the cell.
b. Substances can be moved against a concentration gradient by pumps that do work using the energy provided by ATP hydrolysis.
c. Some channels are capable of moving molecules against their concentration gradients via passive transport.
d. A molecule can be transported into a cell, against its concentration gradient, as long as it is transported along its electrochemical gradient.
e. b and d
Homework Answers
I believe the correct answer to be:
Option E) B and D.
As pumps as well as electrochemical gradient can work against the concentration gradient in a cell.

Many cells take up molecules against their concentration gradients: the molecules are more concentrated inside the cell than outside. Amino acids are frequently transported in this fashion. For the question below, think about intestinal cells growing in medium that is equivalent to blood. The concentration of amino acids is higher in the cell's cytoplasm than in the medium outside the cell. Please indicate whether each of the following modes of transport would permit amino acid uptake into the cell. For...

1. In a cell, a thermodynamically unfavorable process can occur if the process is coupled to a thermodynamically favorable process. the process is thermodynamically favorable outside the cell. an enzyme gives energy to the reacting substances. the cell as a whole is close to equilibrium. 2. In an active transport protein, ATP hydrolysis creates a channel through the membrane. ATP uses the protein to move across the membrane. ATP hydrolysis causes the protein to change shape. ATP carries a substance...
