What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
Statement explains why oxygen molecules easily diffuse across the cell membrane while glucose molecules?
Oxygen molecules easily diffuse across the cell membrane due to their small size and nonpolar nature, allowing them to pass through the lipid bilayer without assistance. In contrast, glucose molecules are larger and polar, requiring specific transport proteins to facilitate their movement across the membrane. This difference in molecular size and polarity determines the mechanisms by which these substances enter or exit cells.
Which molecules will not diffuse directly across the lipid bi layer?
Large polar molecules such as proteins and glucose, as well as ions like sodium and potassium, will not diffuse directly across the lipid bilayer due to their size or charge. These molecules require specific transport proteins or channels to facilitate their movement across the membrane.
What statement explains why oxygen molecules easily diffuse across a cell membrane well glucose molecules do not?
Oxygen molecules are small and nonpolar, allowing them to easily diffuse through the lipid bilayer of the cell membrane without the need for transport proteins. In contrast, glucose is a larger, polar molecule that cannot passively diffuse through the membrane; it requires specific transport proteins to facilitate its movement into the cell. This difference in size and polarity accounts for the varying ease of diffusion for these two substances.
Why glucose molecules can easily pass across the semipermeable cell membrane?
Glucose molecules cannot easily pass through the semipermeable cell membrane due to their size and polarity; they are larger and polar, making them less able to diffuse freely through the lipid bilayer. Instead, glucose requires specific transport proteins, such as glucose transporters (GLUT), which facilitate its movement across the membrane via facilitated diffusion. This process allows glucose to enter cells efficiently without the expenditure of energy.
Why do molecules easily diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
What explains why oxygen molecules diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass through.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
Why oxygen molecules do not across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.
Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?
glucose molecules will diffuse out of the cell. apex
