Active Membrane Transport Practice 2024 - 2025

Movement of molecules from low to high concentration

Movement of molecules from high to low concentration

Transport not requiring energy

Transport requiring energy

Vesicles are expelled out of the cell

Cell absorbs particles by engulfing them

Cell membrane wraps around a particle to form a vesicle

Cell rejects substances by engulfing them

The inside is hypertonic for Na⁺

The outside is hypertonic for Na⁺

The Na⁺ can move through the membrane without a channel or pump

The Na⁺ will move out of the cell through a protein pump

The Na⁺ will move into the cell through a protein pump

The Na⁺ is moving with the concentration gradient

The Na⁺ is moving against the concentration gradient

The movement of Na⁺ requires energy

The movement of Na⁺ does not require energy

The inside is hypertonic for K⁺

The outside is hypertonic for K⁺

The K⁺ can move through the membrane without a channel or pump

The K⁺ will move out of the cell through a protein pump

The K⁺ will move into the cell through a protein pump

The K⁺ is moving with the concentration gradient

The K⁺ is moving against the concentration gradient

The movement of K⁺ requires energy

The movement of K⁺ does not require energy

The inside is hypertonic for glucose

The outside is hypertonic for glucose

The glucose can move through the membrane without a channel or pump

The glucose will move out of the cell through a protein channel

The glucose will move into the cell through a protein channel

The glucose is moving with the concentration gradient

The glucose is moving against the concentration gradient

The movement of glucose requires energy

The movement of glucose does not require energy

The inside is hypertonic for CO₂

The outside is hypertonic for CO₂

The CO₂ can move through the membrane without a channel or pump

The CO₂ will move out of the cell through the membrane

The CO₂ will move into the cell through the membrane

The CO₂ is moving with the concentration gradient

The CO₂ is moving against the concentration gradient

The movement of CO₂ requires energy

The movement of CO₂ does not require energy
