What else can I help you with?
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
What is The process by which small molecules pass through a membrane by moving from an area of high concentration to an area of low concentration is?
This process is called passive diffusion or simple diffusion. It does not require energy input and relies on the concentration gradient to drive the movement of molecules across the membrane.
What is the movement of across the cell membrane using cell energy?
This type of movement is called simple diffusion.
What structural feature of the membrane makes simple diffusion more efficient?
Having a higher surface area-to-volume ratio, such as with microvilli or folded membranes, can make simple diffusion more efficient because it provides more space for molecules to pass through the membrane and increases the rate of diffusion.
How can oxygen cross the membrane?
By the process of simple diffusion.
The process by which simple sugar passes through a membrane is called?
diffusion
When molecules such as oxygen are moved into Cells along their concentration gradient directly through the Cell membrane - this is called?
Trans-membrane diffusion.
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What moves small or lipid soluble solutes through the membrane?
Small or lipid soluble solutes can pass through the cell membrane via simple diffusion. This process occurs without the need for energy or specific transport proteins, as these solutes can move freely through the lipid bilayer of the membrane due to their size or lipid solubility.
What happens in simple diffusion?
In simple diffusion, a substance passes through a membrane without any outside intermediary. The rate of diffusion is based on the force exerted..

What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis

This process is called passive diffusion or simple diffusion. It does not require energy input and relies on the concentration gradient to drive the movement of molecules across the membrane.
What is the difference between facilitated diffusion and simple diffusion in terms of the mechanisms by which molecules move across a cell membrane?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of specific proteins, while simple diffusion does not require any proteins and relies on the molecules moving freely through the membrane.
Can nonpolar molecules cross the cell membrane?
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
What moves products through a cell membrane?
Diffusion, facilitated diffusion, Osmosis and Active Transport. Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!
