How do molecules that are too large to cross the membrance enter into the cell?
Large molecules can enter a cell through endocytosis, where the cell membrane folds around the molecule, forms a vesicle, and brings it into the cell. This process allows the cell to take in nutrients, signaling molecules, and other substances that are too large to pass through the membrane directly.
How do large polar molecules enter the cell?
Large polar molecules enter the cell through facilitated diffusion or active transport, which require the assistance of specific protein channels or carriers in the cell membrane. These proteins help transport the molecules across the membrane against a concentration gradient or when the molecules are too large to pass through on their own.
A large particle can enter a cell by an active transport process called?
Endocytosis - the way in which cells take in food and other materials. The cells membrane wraps around the particle it needs on its outside, ingesting it. This then becomes trapped within a vacuole inside the cells cytoplasm where it is broken down, digested, and absorbed by enzymes.
Can large polar molecules pass through the plasma membrane?
No, large polar molecules cannot pass through the plasma membrane.
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins

A cell will engulf a large particle of matter that would be too large to pass through the membrane?
phagocytosis
Large molecules are surrounded by the cell membrane and enter the cell?
Large molecules can enter cells through processes like endocytosis, where the cell membrane surrounds the molecule and engulfs it in a vesicle. This allows large molecules to be transported into the cell without crossing the lipid bilayer of the membrane.

What kind of particle would move through a cell membrane the easiest- small or large-polar or nonpolar?
Small and nonpolar.
What is the process by which large molecules enter a cell through pouches in the membrane?
The process by which large molecules enter a cell through pouches in the membrane is called endocytosis. During endocytosis, the cell membrane forms a pouch around the molecule, encloses it, and brings it into the cell as a vesicle. This allows the cell to take in larger molecules that would not be able to pass through the membrane on their own.
How does a large particle leave a cell by a active transport?
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
How do large polar molecules enter the cell?
Large polar molecules enter the cell through facilitated diffusion or active transport, which require the assistance of specific protein channels or carriers in the cell membrane. These proteins help transport the molecules across the membrane against a concentration gradient or when the molecules are too large to pass through on their own.
Why did the starch not enter the beaker?
The starch did not enter the beaker because the membrane of the dialysis tubing is selectively permeable, allowing only smaller molecules, like glucose and water, to pass through. Starch molecules are too large to pass through the pores of the membrane, thus they were unable to enter the beaker.
How does water enter and exits a cell?
Through osmosis, which basically is when water moves to where there is less water through a semi-permeable membrane ( a membrane thin enough for smaller substances like water to get through but not large substances).
A large particle can enter a cell by an active transport process called?
Endocytosis - the way in which cells take in food and other materials. The cells membrane wraps around the particle it needs on its outside, ingesting it. This then becomes trapped within a vacuole inside the cells cytoplasm where it is broken down, digested, and absorbed by enzymes.
