9. Transport Across Membranes

In the context of passive transport, osmosis is defined as the movement of which substance across a selectively permeable membrane?

During osmosis across a selectively permeable membrane, which molecule does NOT move across the membrane (assuming only water can pass)?

In cell biology, osmosis can be defined as which of the following?

In passive transport, how does increasing the distance a molecule must travel (diffusion path length) affect the rate of diffusion across a medium when all other factors remain constant?

In passive transport, how does increasing temperature affect the rate of diffusion of small molecules across a solution or membrane (assuming no phase change and constant concentration gradient)?

In the context of passive transport across a selectively permeable membrane, what is the diffusion of water called?

In passive transport, what is the primary driving force of diffusion across a membrane?

In passive transport, how does increasing temperature generally affect the rate of diffusion of small molecules in a fluid environment?

In passive transport by diffusion, what is the principal force driving the net movement of molecules?

In the context of passive transport, simple diffusion across a plasma membrane requires __________.

Which statement best describes facilitated diffusion in the context of passive transport across a cell membrane?

In animal cells, what is the primary mechanism by which water enters the cell across the plasma membrane under normal physiological conditions?

Which of the following is an example of passive transport across a cell membrane?

In osmosis across a selectively permeable membrane, the net movement of water is always from a region with which condition to a region with the opposite condition?
