Active Transport vs Diffusion
Cells move substances in different ways depending on the concentration gradient and the energy available.
Which one needs ATP from respiration?
What is Active Transport vs Diffusion?
"Passive transport (diffusion) moves particles down a gradient; active transport moves them against a gradient using energy."
Diffusion is the net movement of particles:
Why are cultures in school laboratories usually incubated at about 25°C rather than 37°C?
Which change would increase the rate of diffusion?
Which answer best completes the statement? The nucleus contains ____ and controls the cell
Mechanism Comparison
Diffusion is passive (no energy); Active Transport is active (requires energy).
Diffusion moves down the gradient; Active Transport moves against it.
Active transport requires carrier proteins in the cell membrane.
If a question mentions root hair cells or the gut, think about active transport.
