How do gases move across the plasma membrane and other cellular membranes?Multiple choice question.By facilitated diffusionBy passive diffusionThrough specialized gas channelsBy active transport

How do molecules move that are facilitated by active transport?lower concentration to higher concentrationthrough the cell membranehigher concentration to lower concentration

By which mechanism do compounds like oxygen, carbon dioxide, and fatty acids move through a cell membrane?Multiple choice question.diffusionhydrostatic pressureactive transportfiltration

Passive membrane transport processes:move solutes down their concentration gradients in the absence of energyrequire the input of energy to move a solute across the plasma membraneonly transport lipid-soluble solutesalways require the use of channel or carrier proteins to move solutes across the plasma membrane

Facilitated diffusion is considered active transport.Group of answer choicesTrueFalse

Which statement best describes active transport across the plasma membrane?Movement of molecules from an area of higher concentration to an area of lower concentration, requiring energyMovement of molecules from an area of lower concentration to an area of higher concentration, requiring energyMovement of molecules from an area of higher concentration to an area of lower concentration, not requiring energyMovement of molecules from an area of lower concentration to an area of higher concentration, not requiring energy
