Which of the following statements is true about active and passive transport? Select all that apply. Group of answer choices Passive transport always involves molecules diffusing directly through the membrane, without any help. Facilitated diffusion is a type of passive transport that uses ATP to transport molecules through channel proteins. Both passive and active transport can occur through channels in the plasma membrane. Only active transport can transport molecules against their concentration gradient.

Passive transport always involves molecules diffusing directly through the membrane, without any help. This statement is not entirely true. Passive transport can occur through simple diffusion (directly through the membrane) or facilitated diffusion (with the help Show more…

Which of the following statements regarding passive transport is false? All passive transport relies on a concentration gradient as the driving force Facilitated diffusion can move solutions against their concentration gradient Osmosis involves the movement of water to equalize concentrations Ions require special protein transporters to diffuse in and out of the cell

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.

Which of the following statements is true? Active transport moves molecules from low to high concentration, and passive transport moves molecules from high to low concentration. Passive transport requires cell expenditure of ATP to move molecules across the membrane, but active transport does not. Active transport moves molecules down a concentration gradient, and passive transport moves molecules against the concentration gradient.
