Egg white is made up mostly of protein. Proteins are too large to fit through the pores in sausage membranes.

Why cant DNA travel to the cytoplasm?

DNA is too large to pass through the nuclear membrane, which separates the nucleus from the cytoplasm. The nuclear membrane acts as a barrier to prevent DNA from leaving the nucleus to maintain the integrity of the genetic material. RNA molecules are responsible for carrying genetic instructions from the nucleus to the cytoplasm for protein synthesis.


Why cant proteins and polysaccharides diffuse through the membrane like water does?

Proteins and polysaccharides are too large to pass through the hydrophobic lipid bilayer of the cell membrane. Water, being a small molecule, can easily pass through the membrane via simple diffusion. Proteins and polysaccharides typically require specialized transport mechanisms, such as channels or carrier proteins, to facilitate their movement across the membrane.


What part of the membrane would help a large protein molecule enter the cell?

Globular Proteins


Why cant glucose be able to move across a cell membrane by simple diffusion?

Glucose is a large and polar molecule, which makes it difficult to pass through the hydrophobic interior of the cell membrane. As a result, glucose requires specific transporter proteins to facilitate its movement across the membrane.


How do you large molecules and ions pass through the cell membrane?

Recently had a homework on the cell membrane, i do know that larger molecules that cant fit through the polar heads into the cell (like gases can...and small molecules?!) can get through only if they qualify the shape fitting of the channel protein- the one that reaches all the way from the outside to the inside of the membrane. hope this helps
