Multiple Choice

What is one key difference between active transport and passive transport in cells?

• Active transport requires energy from ATP, while passive transport does not.

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

• Active transport only occurs in plant cells, while passive transport occurs in animal cells.

• Active transport does not use carrier proteins, while passive transport does.

Multiple Choice

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

• Active transport requires energy and moves molecules against the concentration gradient, while passive transport does not require energy and moves molecules with the concentration gradient.

• Active transport does not require energy and moves molecules with the concentration gradient, while passive transport requires energy and moves molecules against the concentration gradient.

• Both active and passive transport require energy to move molecules across the membrane.

• Both active and passive transport move molecules from low to high concentration.
