What else can I help you with?
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What is the movement called when a cell does not use energy to move particles across the cell's membrane?
It is called passive diffusion.
Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
Is the process in which molecules move across a cell membrane from a region of low concentration to a region of high concentration.?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What makes the cell membrane selective permeable?
A cell membrane is selectively permeable because it only allows particles to move across them due to different concentrations. Molecules move from areas of low concentration to high concentration.
What does diffusion do in a cell?
Move things across the cell membrane.
What can you conclude about the cell membrane structure if liquid soluble molecules move across the membrane?
It can be concluded that if the liquid soluble molecules move more readily across the membrane then the membrane must be made of lipids. When two parts are made of similar material then they will be more likely to allow other particles like them to pass.
How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
Is passive tansport the answer to particles moving across a cell membrane without using energy?
Yes, passive transport is the process by which particles move across a cell membrane without the input of energy. This can occur through processes like diffusion and osmosis, where particles move down their concentration gradient to reach equilibrium.
What functions to membrane proteins have?
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
Which structures must be present in a cell for osmosis to take place?
For osmosis to occur in a cell, a selectively permeable membrane is essential. This membrane allows water to move across it while restricting the passage of solute particles. Additionally, a concentration gradient of solutes across the membrane is necessary to drive the movement of water into or out of the cell.
