Classify the phrases based on whether they describe or give an example of facilitated diffusion, active transport, or both. Facilitated diffusion Active transport Both Answer Bank movement to area of lower concentration movement across a membrane movement assisted by proteins glucose transport into muscle cell sodium ion transport out of cell requires energy
Diffusion: Which following statement is incorrect? Select one: a. Facilitated diffusion requires a transport protein b. It is a form of passive transport c. Isotonic solutions have an equal amount of solute on both sides of the membrane - no change in shape d. Exocytosis involves the diffusion of molecules out of a cell e. Hypotonic solutions result in cell swelling
How does facilitated diffusion differ from simple diffusion? Facilitated diffusion requires ATP Facilitated diffusion requires a solute-specific protein carrier Facilitated diffusion transports solute against its’ concentration gradient Which of the following is TRUE about primary active cell membrane transport? It is a form of transport that requires a protein “pump” It is a form of transport that transports ions and/or solute against their concentration gradient It is a transport mechanism that requires energy released from the splitting of ATP by...
Which of the following would not be facilitated diffusion? A. An amino acid exits the cell through an integral protein. B. A chloride ion (Cl-) unlocks a protein channel, and passes through. C. A large glucose molecule enters the cell through a pore protein. D. A water molecule passes through a semi-permeable membrane.
A correct distinction between facilitated diffusion and active transport of a substance across a biological membrane is that . . . A. active transport requires conformational changes in the transport protein associated with the transport process, and facillitated diffusion does not. B. active transport requires integral membrane protein to carry out the transport, and facillitated diffusion does not. C. facilitated diffusion depends on an existing energy gradient acting on the transported substance, while active transport makes such a gradient. D....
