Why can oxygen diffuses across a cell membrane by a protein cannot?
Oxygen can diffuse across a cell membrane because it is a small, nonpolar molecule that easily passes through the lipid bilayer of the membrane. In contrast, proteins are larger and often charged or polar, making it difficult for them to traverse the hydrophobic core of the membrane without assistance. Proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane. This difference in size and polarity accounts for the varying transport methods between oxygen and proteins.
Why can oxygen across a cell membrane but a protein cannot?
Because an oxygen atom is very small and a protein is made up of lots of atoms and is therefore very large by comparison.
Why can oxygen defuse across a cell membrane but protein cannot?
Because an oxygen atom is very small and a protein is made up of lots of atoms and is therefore very large by comparison.
Why can oxygen diffuses across a cell membrane but a proton cannot?
Oxygen can diffuse across a cell membrane because it is a small, nonpolar molecule that can easily pass through the lipid bilayer of the membrane. In contrast, protons (H⁺ ions) are charged and polar, making it difficult for them to traverse the hydrophobic core of the membrane without assistance. Protons typically require specific transport proteins, such as ion channels or pumps, to facilitate their movement across the membrane. This difference in size and polarity explains why oxygen can diffuse freely while protons cannot.
What process is responsible for the transport of oxygen and carbon dipxide accrlss the alveolar membrane?
The process responsible for the transport of oxygen and carbon dioxide across the alveolar membrane is called diffusion. This occurs due to the concentration gradients of these gases; oxygen diffuses from the alveoli, where its concentration is higher, into the blood in the capillaries, while carbon dioxide diffuses from the blood, where its concentration is higher, into the alveoli to be exhaled. This passive transport mechanism relies on the differences in partial pressures of the gases.
Why can oxygen diffuses across a cell membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
What process is responsible for transport of oxygen and carbon dioxide across the alveolar membrane?
The process responsible for the transport of oxygen and carbon dioxide across the alveolar membrane is called diffusion. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. This process is driven by differences in partial pressures of these gases on either side of the 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 oxygen diffuses from the alveoli into the blood?
Oxygen diffuses from the alveoli into the blood because of a concentration gradient. The partial pressure of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin membrane of the alveoli into the blood to reach equilibrium.
How does amoeba obtain oxygen?
Amoebas obtain oxygen through diffusion. Oxygen from the surrounding environment diffuses across their cell membrane and into their cytoplasm, where it is used for cellular respiration to generate energy.
Why can oxygen diffuse across a cell membrane but a protein cannot-?
Proteins are to large or Oxygen is much smaller than a protein.
What structure does oxygen diffuses through but a sodium ion may need active transport?
Oxygen can diffuse through the cell membrane, which is selectively permeable to small non-polar molecules. On the other hand, sodium ions are charged and larger, so they typically require active transport mechanisms such as protein pumps to move across the cell membrane.

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.
