When the concentration of free water molecules is higher outside a cell than inside the cell water will diffuse?
In this situation there will be endo-osmosis. The water molecules will diffuse from outside to inside cell.
What is inner structure?
An Internal Structure is the way an organism looks on the outside and an External Structure is the looks on the outside.
The concentration of a sugar is high inside a cell and sightly lower outside the cell What is most likley to occur if the sugar molecule can cross the membrabe?
When sugar molecule crosses the membrane the sugar molecule moves to the outside of the membrane. This is taught in science.
Which way do water particles usually diffuse?
If is Hypotonic, that the water will go inside the cell. If is Hypertonic, That the water will go outside the cell.
What is the Common forms of transport?
Simple Diffusion - Lipid soluble molecules diffuse across the plasma membrane of a cell, uses no ATP energy and only occurs down a concentration gradient.Facilitated Diffusion - Molecules use the aid of proteins scattered throughout the plasma membrane to help them diffuse into or out of a cell, uses no ATP energy and only occurs down a concentration gradient.Co-transport - A molecule such as glucose may have a lower concentration inside a cell than outside so it attaches to a carrier protein, as does a molecule that is higher in concentration inside than outside, a sodium ion for example. The glucose is pulled through the membrane because of its concentration gradient, as this happens the sodium ion is also pulled through. This uses no ATP energy but only occurs if a molecule can move down a concentration gradient (on an exam paper you would have to explain that the sodium moves against a concentration gradient to get full marks).Active transport - A molecule uses the aid of carrier proteins to diffuse against a concentration gradient, this does use ATP energy. The ATP is needed to make the carrier protein change shape. This only occurs against a concentration gradient.
Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?
glucose molecules will diffuse out of the cell. apex
If the concentration of glucose is higher inside the cell than the cell then outside the cell then what will happen by the process of diffusion?
Water will move out of the cell. Glucose will not move into the cell without the help of a helper molecule. Glucose molecules will diffuse into the cell.(APEX)

What will happen if the concentration of glucose in the water outside the cell is higher than the concentration inside?
Water will move out of the cell. Glucose will not move into the cell without the help of a helper molecule. Glucose molecules will diffuse into the cell.(APEX)
What is the job a a receptor molecule?
A receptor molecule is a molecule that receives information from outside the cell. They are embedded in either the plasma membrane or cytoplasm of a cell. A specific molecule on the surface or inside of a cell with a characteristic chemical and physical structure. Many neurotransmitters and hormones exert their effects by binding to receptors on cells.
If the concentration of glucose in the water outside the cell is higher than the concentration inside the cell what will happen?
Water will move out of the cell. Glucose will not move into the cell without the help of a helper molecule. Glucose molecules will diffuse into the cell.(APEX)
What is inner structure?
An Internal Structure is the way an organism looks on the outside and an External Structure is the looks on the outside.
Do molecules must always diffuse into a cell?
not if the concentration is equal inside and outside of the cell
Why is the structure important for the function in cell membrane?
the structure of a molecule affects how it interacts with other molecules -apex
What is an external structure?
A structure outside. A skeleton of an object.
The condition of the outside air at any particular moment is called that?
The condition of the outside air at a particular moment is

When sugar molecule crosses the membrane the sugar molecule moves to the outside of the membrane. This is taught in science.
