Why do oxygen molecules easily diffuse across a cell membrane while glucose molecules do not?
Oxygen molecules are small and nonpolar, which allows them to easily pass through the hydrophobic lipid bilayer of the cell membrane via simple diffusion. Glucose molecules, on the other hand, are larger and polar, making it more difficult for them to move through the nonpolar interior of the lipid bilayer. They require specific transport proteins or channels to facilitate their movement across the membrane.
What substance easily travel across the cell membrane glucose molecules water molecules or sodium?
Of the three, water will move easily. The others require help and therefore the use of energy.
Does the size or the speed of a molecule determines whether it can pass through the pores of a membrane?
The speed doesn't necessarily determine the permeability, but the size does. Smaller molecules such as O2 can easily enter the cell while CO2 leaves the cell. There are other criteria that also determines whether a molecule can pass through the plasma membrane such as its solubility. Fat soluble molecules such as steroids can easily pass through the membrane.
What are you considering when you referring to how easily materials can pass through membrane?
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
Is glucose or sucrose more easily digested by humans?
Glucose and sucrose are both as easily digested as the other by humans. This is because they are both simple sugars.
What properties of glucose prevent it from easily crossing a membrane?
because its large and wont cross the membrane
How do steroids move across the cell membrane?
steroids are lipid in nature n also the plasma membrane is made up of lipids then as a rule of like dissolve like it can seep pass through the membrane
Why do molecules easily diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.

What statement explains why oxygen molecules easily diffuse across a cell membrane which glucose molecules do not?
Glucose is too big to pass throught.

Can glucose pass through a membrane?
Dialysis membranes are typically not permeable to sucrose. Removing sugar from the blood can be dangerous as it can lead to hypoglycemia. Sugar molecules are too large to pass through dialysis membranes.

What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
The enzyme hexokinase catalyzes the first step of glycolysis, and is crucial to initiating the process and preventing the initial substrate from easily traveling out of the cell (as its pre-reaction structure is membrane permeable)?
Glucose, glucose-6-phosphate
Is glucose or sucrose more easily digested by humans?
Glucose and sucrose are both as easily digested as the other by humans. This is because they are both simple sugars.
What food molecule starch or glucose will pass easily through the wall of the small intestine?
glucose because it can easily break down by enzymes than starch
