. For each of the 3 situations below, use an arrow to indicate the net movement of water into or out of the cell through the semipermeable plasma membrane (i.e. osmosis). (Assume that the sugar molecules cannot pass through the plasma membrane in each case.) 1% sugar (inside a circule) 3% sugar (inside a circule) 1% sugar (inside a circule) 5% sugar 1% sugar 1% sugar 3. In each of the drawings above, indicate if the inside of the cell...

9. Diffusion and Effusion. What distinguishes effusion from diffusion? Effusion is the diffusion of very heavy molecules or other partides. During effusion, molecules spread out until their concentration is uniform. During effusion, a gas escapes through a tiny hole in its container. Effusion is the diffusion of very light molecules or other particles

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...

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...

A concentration gradient affects the direction that solutes diffusion. Describe how molecules move with respect to the concentration. How does size affect the rate of diffusion? Does polarity affect the rate of diffusion? Explain your answer. If a piece of celery is placed in a glass of pure water, are the celery cells hypertonic, hypotonic or isotonic compared to the water? In which direction will water move? What is the water potential of pure water? Why don’t red blood cells...

_____membranes proteins are associated with the bilayer through interactions with other membrane component on the surface of the membrane. Net movement of particles from a region where they are more concentrated to a region where they are law concentrated is called Diffusion of water through a selectively permeable membrane down its own concentration gradient It called A solution with an equivalent concentration of water and hence the tame osmotic pressure as the fluid inside the cell is said to be...

Magnesium ions move out of a cell through a transmembrane protein down (i.e. with) their concentration gradient. The energy harvested from this movement of magnesium ions is used to move sodium ions into the cell against their concentration gradient. This is an example of which type of transport? symport ABC transport antiport facilitated diffusion
