To match: The means of membrane transport on the left with the direction of movement on the right. Introduction: Any substance that passes between cells and the enveloping extracellular fluid must possess the tendency to pass through the plasma membrane. If a component can pass through the membrane, the membrane is considered permeable for that component, however, in case if the component cannot pass, then the membrane is considered impermeable to it. The plasma membrane possesses the tendency of selective permeability, that is, it allows some of the particles to go through while inhibiting the others.

Identify whether each method of membrane transport is passive or active by dragging the label to the correct box

The surface area to volume ratio affects the ability of the cell to exchange nutrients and waste products with the outside environment. Many factors affect the movement of molecules across the cell membrane, including membrane thickness, temperature, pressure, concentration gradient, molecular mass, distance travelled, solvent properties and surface area of the cell. In general, according to Einstein’s approximation equation (Equation 1), diffusion time is inversely proportional to the to the diffusion coefficient (D), where t is time and x is distance travelled. The diffusion coefficient is unique to each type of molecule and is determined experimentally. Waste products such as carbon dioxide (CO2) pose a unique problem to cells as their accumulation may be lethal. Exchange with the external environment is dependent upon the distance the waste must travel; for a round cell this will be up to half the cell diameter. Using the diffusion coefficient (D) for carbon dioxide (1.97 × 10-5…
