Cellular Transport

Multiple Choice

Which of the following best describes the main difference between passive transport and active transport across a cell membrane?

• Passive transport requires energy, while active transport does not.

• Active transport moves substances from high to low concentration, while passive transport moves from low to high concentration.

• Passive transport moves substances down their concentration gradient without energy, while active transport moves substances against their concentration gradient using energy.

• Both passive and active transport require carrier proteins and energy.

Multiple Choice

What happens to an animal cell placed in a hypotonic solution?

• It shrivels up as water leaves the cell.

• It remains unchanged as water moves in and out equally.

• It swells and may burst as water enters the cell.

• It divides rapidly.

Multiple Choice

A solution in which water flows out of a cell is called a ___ solution.

• hypertonic
• hypotonic

• Isotonic

Multiple Choice

Which statement best describes the role of the cell membrane in this model?

• The cell membrane is an impermeable barrier that prevents water from entering the cell.

• The cell membrane allows solutes to enter the cell, which causes the cell to shrink.

• The cell membrane allows water to enter and leave the cell.

• The cell membrane removes solutes from the environment.

Multiple Choice

Which of the following best describes the difference between passive transport and active transport in cellular transport?

• Passive transport requires energy/ATP, while active transport does not.

• Passive transport uses carrier proteins, while active transport uses channel proteins.

• Passive transport moves substances from low to high concentration, while active transport moves them from high to low concentration.

• Passive transport does not require energy/ATP and uses channel proteins, while active transport requires energy/ATP and uses carrier proteins.
