Question and answer
what would happen to a jellyfish if placed into freshwater lake
Facilitated diffusion involves proteins known as carriers, which, as in the case of ion channels, are specific for a certain type of solute and can transport substances in either direction across the membrane. [ However, unlike channels, they facilitate the movements of solutes across the membrane by physically binding to them on one side of the membrane and releasing them on the other side.
The direction of the solute's net movement simply depends on its concentration gradient across the membrane. If the concentration is greater in the cytoplasm, the solute is more likely to bind to the carrier on the cytoplasmic side of the membrane and be released on the extracellular side, and there will be a net movement from inside to outside. If the concentration is greater in the extracellular fluid, the net movement will be from outside to inside. Thus, the net movement always occurs from high concentration to low, just as it does in simple diffusion, but the process is facilitated by the carriers. (Compare with active transport in which energy is expended to move substances against a concentration gradient.) ]

Weegy: It eats itself.



User: explain the difference between passive transport and active transport

Weegy: ctive transport requires energy and Passive transport requires no energy. Passive transport is a process which is carried out along the concentration gradient. [ For example, if the concentration of water is more outside the cell than inside, water will flow into the cell. Simply put, it is actually diffusion which occurs in passive transport and hence, no energy is required. Active transport, however, is carried out against the concentration gradient and hence requires energy. An example of active transport is the uptake of salt by cells through sodium pump. Active transport requires energy and moves particles up their concentration gradient. Passive transport doesn't require energy and moves particles down their concentration gradient. ]

User: what functions do carrier proteins perform in active transport

Weegy: Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.

what functions do carrier proteins perform in active transport User: what provides the energy that drives the sodium potassium pump
Weegy: Adenosine TriPhosphate or "ATP". is used in weukaryotes and PMF i.e. proton motive force is a source of active transport. Energy is supplied directly or indirectly by ATP User: explain the difference between pinocytosis and phagocytosis Weegy: Endocytosis occurs when a substance is brought into the cell. Phagocytosis is a type of endocytosis , and is called cell eating. Pinocytosis is cell drinking, another type of endocytosis. User: describe the steps involved in exocytosis (More)
