Question

some molecules require cellular energy to pass through the cell membrane. other molecules can pass through the cell membrane without energy from the cell. match the terms to their definitions. passive transport active transport term definition the movement of molecules across the cell membrane using cellular energy the movement of molecules across the cell membrane with no additional energy from the cell

Explanation:

1. For the first definition "the movement of molecules across the cell membrane using cellular energy", this matches the concept of active transport because active transport requires energy (usually ATP) to move molecules against their concentration gradient.
2. For the second definition "the movement of molecules across the cell membrane with no additional energy from the cell", this matches passive transport. Passive transport (like diffusion, osmosis, facilitated diffusion) does not require the cell to expend energy as molecules move along their concentration gradient.

Answer:

• First term (movement using cellular energy): active transport
• Second term (movement with no cell energy): passive transport
