i don't know i need help pleas?
Passive diffusion is the movement of molecules across a cell membrane from an area of high concentration to low concentration without the need for a protein carrier. Facilitated diffusion, on the other hand, requires the presence of specific protein channels or carriers to help molecules move across the membrane.
Binary diffusion is the process where two different chemical species, such as molecules or ions, mix and move through each other in a medium, like a gas or liquid. This diffusion occurs due to differences in concentrations and generates a net transport of one species in the presence of the other. Binary diffusion is an important phenomenon in various fields, including chemistry, physics, and engineering.
There are quite a few differences between mitosis and meiosis. Meiosis for example only happens in the sex cells of an organism.
they both was man. but lewis was older then clark
Cats do not have seminal vesicles therefore there is no difference.
both need transport protein
Diffusion is the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion involves the use of transport proteins to move specific molecules across the cell membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Facilitated diffusion is a passive process that uses carrier proteins to transport molecules across the cell membrane along their concentration gradient, while active transport is an energy-dependent process that uses ATP to move molecules against their concentration gradient through protein pumps.
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules move down their concentration gradient across the cell membrane.
They both require a trans membrane protein. Facilitated diffusion does not require energy whereas active transport requires energy. Facilitated diffusion takes place when there is a net movement of molecules from a region of high concentration to a region of low concentration whereas active transport takes place when there is a net movement of molecules from a region of low concentration to a region of high concentration.
The three methods are diffusion, facilitated diffusion, and active transport. Diffusion involves the movement of particles from an area of higher concentration to an area of lower concentration. Facilitated diffusion requires the assistance of transport proteins to move molecules across the cell membrane. Active transport uses energy to move molecules against their concentration gradient.
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
Both active transport and facilitated diffusion are mechanisms that transport molecules across the cell membrane. They both involve the movement of molecules from an area of higher concentration to an area of lower concentration. However, active transport requires energy input from the cell to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules pass through the membrane.
Facilitated diffusion is a carrier-mediated form of transport across a membrane. The line-with-gaps model doesn't show the carrier proteins that are in the cell membrane. These proteins are what help facilitated diffusion occur.
Oxygen uptake and glucose uptake will differ in terms of the transport mechanisms involved, as oxygen is taken in by simple diffusion while glucose requires facilitated diffusion. Other factors such as energy requirements, concentration gradients, and specific transport proteins involved may also vary between the two processes.
