Large molecules such as proteins and nucleic acids cannot pass through the cell membrane.
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
No, large polar molecules cannot pass through the plasma membrane.
Charged molecules cannot pass through the membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through based on their size and charge. The charged molecules are repelled by the hydrophobic interior of the membrane, which prevents them from crossing.
Yes, charged molecules can pass through the membrane.
Yes, hydrophobic molecules can pass through a membrane because the lipid bilayer of the membrane is also hydrophobic, allowing them to move through easily.

Yes, charged molecules can pass through the membrane.
Ions cannot pass through such as Na+ and K+ - these require membrane proteins. Some larged polar molecules cannot cross either - such as glucose and sucrose - these also require membrane proteins.
Large polar molecules and charged molecules cannot pass directly through the phospholipids of the plasma membrane because the phospholipid bilayer is impermeable to them. Instead, these molecules rely on specific transport proteins like channels or carriers to facilitate their movement across the membrane.
Carbohydrates cannot pass directly through the cell membrane. some important molecules are too large to pass through the cell membrane
Yes, hydrophobic molecules can pass through a membrane because the lipid bilayer of the membrane is also hydrophobic, allowing them to move through easily.
Whether molecules are able to pass through the membrane depends on the size of the molecules. Smaller ones can, and larger ones cannot. Glucose can pass through a cell membrane because it is a monomer, which is a smaller molecule than the polymer molecules of starch.
Yes, polar molecules can pass through the cell membrane with the help of specific transport proteins.
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
No, iodine potassium iodide mixed with starch cannot diffuse through a semipermeable membrane because the starch molecules are too large to pass through the pores of the membrane. Only smaller molecules like iodine will be able to pass through.
