If the large molecule won't pass through the membrane by diffusion, it might be dragged through the membrane by "endocytosis".

How do large polar molecules enter the cell?
The polar molecules goes through facillated diffusion. The molecules goes through the channel or membrane protein which then goes inside the cell.
What type of molecules enter the cell through passive transport List at least three?
They are molecules with low weights.Their surface charge must be very low. Water,some amino acids, some other chemicals enter this way
What will happen when a membrane sac filled with large molecules of oil is suspended in a beaker of water?
Water will enter the sac and it will swell
What happens when a membrane sac filled with large molecules of oil is suspended in a beaker of water?
Water will enter the sac and it will swell
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
What type of molecule embedded in the cell membrance allows larger molecule to pass through the membrance by active transport?
Transport proteins allow the active transport of large molecules through the cellular membrane.
Large solutes are transported across a cell membrance by?
exocytosis
How do most molecules cross the cell membrane?
Diffusion or if the molecules are too large they go through the transport proteins.
The nucleus is surrounded by a semipermeable membrane. what would happen if this layer were permeable to most substances?
Large molecules would be able to enter and damage the nucleus.
What is the process by which large molecules enter a cell through pouches in the membrane?
Phagocytosis
What kind of substances do protein channels allow to cross membranes?
Ions and large molecules
What part of the membrane helps large carbohydrate molecules enter the cell?
Globular proteins
What part of the membrane would help a large carbohydrate molecules enter the cell?
Globular proteins
How do large polar molecules enter the cell?
The polar molecules goes through facillated diffusion. The molecules goes through the channel or membrane protein which then goes inside the cell.
Large molecules are surrounded by the cell membrane and enter the cell?
A large molecule that can not enter the cell through myosis enters the cell through by endocytosis. Endocytosis is an example of active transport.
What is the basis of molecular sieve chromatography?
The purification in molecular sieve chromatography is dependent on the size of the molecules. The small molecules will enter into pores of gel while large molecules will be excluded from the pores.
What type of molecules enter the cell through passive transport List at least three?
They are molecules with low weights.Their surface charge must be very low. Water,some amino acids, some other chemicals enter this way
