Question

The concentration of solute is more on the outside of a cell but still it is entering into the cell through the cell membrane. Which of the following is true as per the statement?

• A. Energy is being expended by the cell
• B. The solute is moving against its concentration gradient
• C. The solute molecules are hydrophilic
• D. Solute concentration is higher inside than outside the cell
  
• E. Both A and B

Answer 1

Answer: (E)

Both A and B

Since the concentration of solute is more outside the cell it is moving against it's concentration gradient. To do this energy must be used and this is termed as active transport.

Hydrophilicity does not explain the movement in this condition.

So the correct answer is 'Both A and B'.
