What else can I help you with?
Why can oxygen diffuse across a cell membrane but a protein?
Its too large
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.
Which type of transport is the coupled passage of two materials across a membrane?
Symport is the type of transport that involves the coupled passage of two materials across a membrane in the same direction. It relies on a concentration gradient to move both substances across the membrane simultaneously.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
How plasma membrane diffuse across plasma membrane?
Ions can't diffuse across membranes, they must used channels to transport across
Which can diffuse across a cell membrane without a transport protein carbohydrates lipids or proteins?
Lipids can diffuse across a cell membrane without a transport protein. This is because lipids are generally hydrophobic and can easily pass through the lipid bilayer of the membrane. In contrast, carbohydrates and proteins are typically larger and more polar, making them unable to cross the membrane without assistance from transport proteins.

What is the process of moving materials across membrane with energy?
active transport
Which type of transport is the coupled passage of two materials across a membrane?
Symport is the type of transport that involves the coupled passage of two materials across a membrane in the same direction. It relies on a concentration gradient to move both substances across the membrane simultaneously.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
What is the pumping of materials across a membrane against their concentration gradients?
Active Transport
How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
