a membrane?
OOO
The rate of transport is saturable.
It is highly specific for the molecule being transported.
All of the answers are correct.
Its rate is higher than that of simple diffusion of the molecule.
The direction of transport is determined by concentration and/or electrochemical gradients.
Which of the following statements is NOT TRUE about membrane transport?
to facilitate movement of ions and molecules across membranes.
to move food, water, and wastes around, into, and out of a cell.
to get rid of duplicated organelles in a cell.
to transport proteins, lipids, and other molecules synthesized by the cell.
Which of the following statements about active processes of membrane transport is true?
cellular energy is required
substances move against its concentration gradient
all requires the aid of proteins during transport

- Which of the following is true regarding the permeability of the cytoplasmic membrane? Nothing can diffuse across the membrane All molecules can freely diffuse across it Only non-polar molecules can diffuse across the membrane It is generally impermeable to ions, polar moleculesarrow_forwardWhat is NOT true about diffusion: 1. A form of passive transport. 2. Uses adenosine triphosphate to transport substances across the plasma membrane. 3. Tendency of molecules to move from an area of higher concentration to an area or lower concentration. 4. Classified as either facilitated diffusion or simple diffusion.arrow_forwardWhich of the following are features of facilitated diffusion? There may be more than one correct answer, select all that apply. Requires energy Movement assisted by proteins Can include passive diffusion Depends on ATP hydrolysis Can include ion transport down its concentration gradient in a cell (high to low concentration)arrow_forward
