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.

What are three macromolecules that cannot diffuse across a cell membrane?
Any protein, any fat, and most polypeptides.
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.
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 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.
Can ATP passively diffuse across cell membrane?
The universal energy molecule of the cell, adenosine triphosphate (ATP) cannot passively diffuse across the cell membranes. Despite its low molecular weight, ATP carries a strong negative charge making it hydrophilic and thus unable to diffuse across the lipophilic cellular membrane.
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?
Its too large
What are three macromolecules that cannot diffuse across a cell membrane?

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 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.

What must be used to transport materials that cannot diffuse across the membrane?
Transport proteins, such as channels and carriers, must be used to transport materials that cannot diffuse across the membrane. These proteins facilitate the movement of specific substances across the cell membrane by providing a passageway or binding site for the molecules to move through.

What is an impermeable solute?
An impermeable solute is a substance that cannot pass through a semipermeable membrane, such as a cell membrane. This means that the solute is unable to diffuse or move across the membrane and remains on one side of the membrane.
Can ATP passively diffuse across cell membrane?
The universal energy molecule of the cell, adenosine triphosphate (ATP) cannot passively diffuse across the cell membranes. Despite its low molecular weight, ATP carries a strong negative charge making it hydrophilic and thus unable to diffuse across the lipophilic cellular membrane.
