Ions typically cannot travel through the cell membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through. The structure of the cell membrane does not easily allow ions to pass through, so they require specific channels or transport proteins to facilitate their movement into or out of the cell.

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
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
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 does how does light travel through opaque material?
it cant travel through light.
What cant secondary waves travel through?
Ocean
What sound cant travel through?
sound can't travel through a vacuum. or a place without air.
Why do insulators prevent electric shocks?
because electricity cant travel through them
Why can't sound travel on an asteroid?
sound cant travel on an asteroid because it has no atmosphere. it could travel through it.
What can light travel through that sound cant travel through?
Light can travel through a vacuum, such as outer space, where sound cannot travel as it requires a medium like air, water, or a solid to propagate. Light can also travel through transparent materials like glass or air, while sound is mostly blocked or absorbed by these materials.
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 sound trave through empty space?
Sound requires a medium, such as air or water, to travel through. In the absence of a medium, such as in empty space, there are no particles for sound waves to propagate through, so sound cannot travel.
Why cant you listen sound on the moon?
There is no air for sound to travel through.
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.

Proteins and polysaccharides typically require specialized transport mechanisms, such as channels or carrier proteins, to facilitate their movement across the membrane.
What is a material that light can't travel through?
There is no known material that light cannot travel through. However, materials such as lead and thick concrete can significantly attenuate or absorb light, making them almost opaque to visible light.
What does seminpermeable membrane do?
semi permeable membrane is semi-permeable or not completely permeable...it allows particles of a certain shap or size flow through but other shapes that are large or snaller cant fit through.
