How is active transport different from simple diffusion? Both active transport and simple diffusion transport molecules against the concentration gradient. In active transport, molecules are moved down the concentration gradient; on the B contrary, molecules to be transported in simple diffusion are moved against the concentration gradient. In active transport, molecules are transported with the aid of transport proteins; on the © other hand, molecules to be transported in simple diffusion do not need transport proteins. In active transport, molecules that are transported does not need metabolic energy; in contrast, molecules transported in simple diffusion need metabolic energy.

rate of transport Vmax 1/2Vmax transporter-mecated diffusion Km simple diffusion concentration of transported molecule The graph at left shows rates of movement across a cell membrane for a substance that uses simple diffusion (green) and a transport mechanism (red). Which of the following is TRUE about the transporters at the point shown by the arrow? A. The transporter proteins are operating more slowly than at lower concentrations. B. The transporter proteins are operating as fast as possible. C. The transporters proteins shut off at that concentration. D. The rate slows because transporter proteins run out of ATP.
For this practice problem, would the answer be c)NaCl? My reasoning behind this is because molecules under 100 Da can use simple diffusion, while nonpolar molecules and larger molecules like benzene can use channels via facilitated diffusion. However, NaCl dissociates into ions and cannot readily use diffusion?
Match the following statement related to membrane transport processes to the appropriate term or terms: passive transport, facilitated transport, active transport. A transporter (or carrier) protein is necessary. (Select all that apply.) passive transport facilitated transport active transport O O
Active transport across membrane can be mediated by the following mechanisms: “Uphill” transport is powered by energy from photons. A solute is driven “uphill” compensated by a different solute being transported “downhill.” “Uphill” transport is powered by ATP hydrolysis. All of the above. None of the above.
