Question

model of cell membrane
below is a model of a plasma membrane. use the model to answer the corresponding questions.
drag and drop the appropriate descriptions in the correct boxes to compare active and passive transport. there will be two descriptors per box.
passive transport
active transport
moves molecules with the gradient, from a high concentration to a low concentration
moves molecules against the gradient, from a low concentration to a high concentration
does not require atp
requires atp

Explanation:

• Passive Transport: This type of transport does not need energy (ATP) as molecules move down their concentration gradient (from high to low concentration). Examples include diffusion and facilitated diffusion.
• Active Transport: This requires energy (ATP) because molecules are moved against their concentration gradient (from low to high concentration), often with the help of transport proteins that use ATP, like the sodium - potassium pump.

Answer:

Passive Transport:

• Moves molecules with the gradient, from a high concentration to a low concentration
• Does not require ATP

Active Transport:

• Moves molecules against the gradient, from a low concentration to a high concentration
• Requires ATP
