What can oxygen diffuse across a cell membrane but protein cannot?
Oxygen can diffuse across a cell membrane because it is a small, nonpolar molecule that can pass through the lipid bilayer easily without the need for transport proteins. In contrast, proteins are larger and typically polar or charged, making it difficult for them to traverse the hydrophobic core of the membrane. As a result, proteins usually require specific transport mechanisms, such as channels or carriers, to cross the membrane.
Why can oxygen diffuse across s cell membrane but a protein cannot?
Oxygen can diffuse across a cell membrane because it is a small, non-polar molecule that can easily pass through the lipid bilayer of the membrane. In contrast, proteins are large and often polar or charged, making it difficult for them to traverse the hydrophobic core of the lipid bilayer without assistance. Proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane.
Why can oxygen diffuse across the cell membrane but protein cannot?
Oxygen can diffuse across the cell membrane due to its small size and nonpolar nature, allowing it to easily pass through the lipid bilayer without the need for transport proteins. In contrast, proteins are larger and often polar or charged, making it difficult for them to traverse the hydrophobic core of the membrane. Consequently, proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane.
Why can oxygen diffuse across the cell membrane the protein cannot?
Oxygen can diffuse across the cell membrane because it is a small, nonpolar molecule, allowing it to pass through the lipid bilayer easily due to the hydrophobic nature of the membrane. In contrast, proteins are larger and polar or charged, which prevents them from readily crossing the lipid bilayer without assistance. Instead, proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane. This difference in size and polarity is key to the distinct transport processes for oxygen and proteins.
Why can oxygen disfuse across a cell membrane but a protein cannot?
Oxygen can diffuse across a cell membrane because it is a small, nonpolar molecule that can easily pass through the lipid bilayer without the need for transport proteins. In contrast, proteins are larger and typically polar or charged, making it difficult for them to traverse the hydrophobic core of the membrane. Instead, proteins usually require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane. This difference in size and polarity determines their ability to diffuse freely.
Why can oxygen diffuse across a cells membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
Why can oxygen diffuse across a cell membrane but a protein cannot-?
Proteins are to large or Oxygen is much smaller than a protein.
Why can oxygen diffuse across a cell membrane but a protein?
Its too large
Why can oxygen diffuse across a cell membrane but a protein can't?
Oxygen is a small, non-polar molecule that can passively diffuse across the lipid bilayer of a cell membrane. Proteins, on the other hand, are larger and more complex molecules that cannot pass through the hydrophobic core of the membrane. Instead, proteins are transported into or out of cells through specific channels or transporters.
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.
Why can oxygen diffuses across a cell membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.

How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.

Why can oxygen diffuse access a cell membrane but a protein cannot?
Oxygen molecules are small and non-polar, allowing them to easily pass through the lipid bilayer of a cell membrane via simple diffusion. Proteins, on the other hand, are typically large and polar molecules that cannot readily pass through the hydrophobic core of the lipid bilayer. Instead, proteins rely on specific transport mechanisms like protein channels or carriers to cross the cell membrane.

Does oxygen diffuse through a semipermable membrane?
yes
