I believe the answer is when it is uncharged.
What else can I help you with?
When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What type of molecule would be likely to diffuse across the phospholipid bilayer of the cell membrane?
an ion
What is a cell plasma membrane?
the outer most part of the cell where items diffuse into the cell, and waste diffuses out of the cell to be disposed.
Which molecule would most likely be actively transported?
A larger molecule or a polar molecule that cannot passively diffuse through the cell membrane would most likely be actively transported. Examples include glucose, ions (such as sodium and potassium), and amino acids.
Would fat particles more likely be brought into a cell then oxygen particles?
No, fat particles are too large to diffuse easily through the cell membrane. Oxygen particles, being smaller, can diffuse freely into cells for cellular respiration.
What characteristics is more likely to make a substance diffuse through the cell membrane?
Size. Actually very few substances are able to diffuse across the menbrane, most must be transported ie facilitated diffusion, active transport, or receptor-mediated endocytosis. Carbon dioxide, oxygen, water, and some lipid substances are able to diffuse across the membrane
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
Can oxygen diffuse across a cell membrane?
No, oxygen cannot directly diffuse across a cell membrane. Instead, it crosses the cell membrane with the help of specific transport proteins, such as aquaporins and oxygen channels. These proteins facilitate the movement of oxygen from areas of high concentration to low concentration.
What are three macromolecules that cannot diffuse across a cell membrane?
Any protein, any fat, and most polypeptides.
What happens to most of the digested food carried by the capillaries?
the capillaries diffuse the digested food to every cell in the body
What will not diffuse through the cell membrane?
Glucose
Which molecule would be unable to diffuse through a cell membrane?
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
