Globular proteins.
What else can I help you with?
What are the parts of the membrane help large molecules pass through it?
Globular proteins.
Facilitated diffusion moves large molecules through what?
Glucose and polypeptides.
Why would the cells need to go through exocytosis?
Many cells in the body use exocytosis to release enzymes or other proteins that act on other parts of the body or to release molecules that helps cells to communicate with each other.
How do Integral membrane proteins function?
The location of their polar and non-polar amino acids. I'll buy that. But there's more. the membranes are hydrophyllic (polar) on the outside and hydrophobic (non-polar) on the inside. Proteins that pass through the membrane are stabilized by the membrane, and also stabilize the membrane in return. Based on the sequence of the amino acids, there are polar / hydrophyllic parts of the protein and nonpolar / hydrophobic parts. They interact with the membrane like little magnets to hold everything in place...
What happens in each of the three main parts of facilitated diffusion?
Binding: Molecules from the extracellular environment bind to the carrier protein on the cell membrane. Transportation: The carrier protein undergoes a conformational change, allowing the molecules to pass through the membrane. Release: Once inside the cell, the molecules are released from the carrier protein and the protein returns to its original conformation for further transport.

What are the two major types of active transports?
The two major parts of active transport are endocytosis and exocytosis. Endocytosis is taking material into the cell by means of infoldings in the cell membrane. There are two types of endocytosis: phagocytosis (large molecules) and pinocytosis (small molecules). Exocytosis is the release of materials from a cell. The vacuole membrane and the cell membrane fuse together and the contents are released.

What can you conclude about the cell membrane structure if liquid soluble molecules move across the membrane?
It can be concluded that if the liquid soluble molecules move more readily across the membrane then the membrane must be made of lipids. When two parts are made of similar material then they will be more likely to allow other particles like them to pass.

Proteins are transported from the nuclear membrane to other parts of the cell through the?
Newly synthesized proteins are transported from the nuclear membrane to other parts of the cell through the endoplasmic reticulum. The endoplasmic reticulum is a flattened and highly-folded organelle that lies near the nucleus in a eukaryotic cell.
What regulates which substances enter and leave a cell?
The plasma membrane. Carrier proteins and ion channels are parts of the plasma membrane, and aid in diffusion across concentration gradients, as most things don't freely move from one end of the cell membrane to the other. The Sodium-Potassium pump is a major ion channel in the plasma membrane, and regulates the intake of potassium and export of sodium (3 molecules sodium out, 2 molecules potassium in.)

Which parts of cell membrane would help a large protein molecule enter the cell?
Globular Proteins
What is the phYSICAL parts of cell membrain?
The physical parts of a cell membrane include phospholipid molecules that form a lipid bilayer, proteins embedded within the lipid bilayer, cholesterol molecules that help regulate membrane fluidity, and carbohydrates attached to proteins and lipids on the outer surface. Together, these components make up the structure of the cell membrane, providing a selectively permeable barrier that separates the cell from its external environment.
