What else can I help you with?
What kind of substance cannot pass through the cell membrane?
lipids, and ribosomeslipids
What substance cannot pass directly through the phospholipids of the plasma membrane?
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.
What cannot pass through nuclear pores?
Large molecules such as proteins and RNA complexes cannot pass through nuclear pores, as these pores have size restrictions and require specific signals for transport. Additionally, molecules that are not recognized by the nuclear transport machinery or that are too large to fit through the pores are also unable to pass through.
State one reason why some molecules can pass through a certain membranebut other molecules can not?
Molecules can pass through a membrane if they are small enough to fit through the pores or channels in the membrane. Larger molecules may not be able to pass through due to their size, charge, or inability to interact with the membrane components.
Where chemicals pass between cells and blood are called?
The area where chemicals pass between cells and blood is called the interstitial space. This space contains fluid that surrounds the cells and allows for the exchange of nutrients, waste products, and signaling molecules between the blood and the cells.
What are the three molecules that cannot easily pass through the membrane?
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
Which molecules cannot pass through the membrane?
Large molecules such as proteins and nucleic acids cannot pass through the cell membrane.
What substance cannot be absorbed directly into the blood?
Large molecules, such as proteins and polysaccharides, cannot be absorbed directly into the blood because they are too big to pass through the walls of the intestine. Instead, they need to be broken down into smaller molecules before they can be absorbed.
Can large polar molecules pass through the plasma membrane?
No, large polar molecules cannot pass through the plasma membrane.
What kind of substance cannot pass through the cell membrane?
lipids, and ribosomeslipids
How many oxygen molecules does have to pass through from the alveolus to get into the blood?
3 or 4
What Process in which food molecules pass from the small intestine to the blood?
Absorption is the process
Do Nutrient molecules pass from the small intestine into the blood stream through the villi?
Yes.
What is the process when nutrient molecules pass through the wall of digestive system into your blood?
Absorption.
How can you get thc out in 2 days to pass a blood test?
You cannot. It is not possible.
What is the components of blood that cannot pass the dialysis tuning?
First of all, it is called Dialysis Tubing. Secondly, they are not 'Components', they are 'Contents'. Thirdly, only small molecules can pass through the semi-permeable membrane of the tubing, if using Diffusion. If using Osmosis, only water can pass through.
What will happen to your blood vessels if you eat to much fat?
The blood vessels will be more thinner, blood cannot pass smoothly and thus you will have blood pressure.
