Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
Answer this que
Oxygen molecules fit between fatty acids, but protein molecules are too big. stion…
Oxygen is much smaller and a gas while proteins are a lot larger and can't diffuse across the membrane. They need a carrier molecule.
If there's a transfer protein then its NOT diffusion ... its active transport.
Its too large
Proteins are to large or Oxygen is much smaller than a protein.
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
identify the name and purpose of the cell membrane proteins that look like tunnels
Water molecules freely diffuse across a semipermeable membrane.
Oxygen molecules diffuse across the membrane.
Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.
If there's a transfer protein then its NOT diffusion ... its active transport.
Its too large
Its too large
Oxygen is much smaller than a protein
Lipid-soluble molecules such as O2 and CO2 diffuse freely through the plasma membrane.
Proteins are to large or Oxygen is much smaller than a protein.
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
