Which of the following statements is/are TRUE for transport across a biological membrane via carrier (transporter) proteins? Select all that apply: Transport is driven by a solute concentration gradient. Transport can be driven by ATP. Transport is irreversible. Transport requires a conformational change in the protein. Transport occurs through a pore or a channel.

Which of these statements is TRUE for passive transport across a biological membrane? Choose only those which apply. Passive transport is dependent on both, a solute electrochemical gradient and ATP. Passive transport is irreversible - a transporter can provide transport only in one direction. Passive transport is reversible - a transporter can provide transport in both directions. Passive transport can be provided by channels, but not by carrier transporters. Passive transport is driven by a solute electrochemical gradient.

Four of the following statements are true regarding facilitated diffusion. Which one is false? It requires ATP The transported substance and the transport protein are usually specific to each other. It can occur through a permanently open channel. It requires a transport protein. Movement follows the concentration gradient of the substance.
