The 2type of groups that are called transport mechanisms and assist in the movement of water/dissolve substances across the cell membrane?
Passive Transport &
Active Transport
Transport mechanisms require no energy(ATP)& these mechanisms cause water/dissolved substances to move without energy,like a ball rolling downhill?
Passive Transport
Name some of the Passive Mechanisms that move substances across the membrane?
Diffusion, Facilitated diffusion, Osmosis and Filtration!
The most common passive transport mechanism? Moves a substance from a higher area of concentration to an area of a lower concetration?
This causes oxygen to move across the membrane of the alveolus of the lung into the blood?
A passive transport mechanism in which glucose is helped across the cell membrane by a helper molecule? Helps mover from a higher to lower also.
Facilitated diffusion
Means it is a help molecule.
A kind of diffusion of water through a selectively permeable membrane. Water diffuses from an area w/more water to one with less?
The capacity to pull water & the strength of the pressure is related directly to the concentration of the solution?
Osmotic pressure
This pressure pulls water into a compartment causing swelling!
This solution has the same concentration as the solution to which it is compared? Means the same, no water is lost or gained?
Isotonic Solution
Because of this kind of solution,no net movement of water occurs;the cell neither gains or loses water.
This solution causes the RBC to burst or lyse. It is more dilute than inside the cell? When RBC place in pure water?
Hypotonic Solution
This is a salt solution causing the RBC to shrink or crenate?
Hypertonic Solution
This when water/dissolved substances cross the membrane in response to differences in pressure? Pressure/force push the substances across the membrane?
This kind of transport that nds energy (ATP) to achieve its goal, to move from a low area of concentration to a high area.
Active Transport
The transport mechanism(endo) that takes in food or liquid by the cell membrane,because the particle is to large to move across the membrane by diffusion?
A lysosome (phago) that eats or ingests a bacteria,helping the body defend itself against infection?
A protein-containing vesicle (exo) within the cell fuses w/the cell membrane and ejects the protein?
The pancreas cells make proteins for use outside the pancreas.
Passive Transports like Diffusion,Fdiffusion,filtration and Osmosis do what?
Passive Transports which move move substances from a higher Concentration to a lower Concentration without energy.
This kind of Transport require energy to move substances from a low concentration to a higher one?
Active Transport Mechanisms
Means the intake of liquid droplets by the cell membrane; also called "cellular drinking."
Moves substances out of the cell?
Transport mechanism that involves the intake of food or liquid by the cell membrane?
