The lab coat almost serves like a second skin. If you were to spill something in lab, instead of getting it on your clothes and on your skin, you would instead get it on the lab coat.
To prevent getting chemicals on you or you clothes. Because you don't want to get something like Potassium magnate (VII) on your shirt!
A lab coat is a first line of defense in lab. If you were to spill something in lab you would get it on the coat instead of on your skin or on your own clothes.
1. To keep potentially dangerous chemicals off of their clothing
2. To be able to quickly see what is on their lab coats. White shows stains well.
The coat is protection from corrosive and toxic chemicals, and the white colour makes it easy to see both stains where such materials may have struck, and possible contaminants before entering the laboratory.

What is the purpose of transport for proteins?
Carrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which theytransportsubstances.
What part of cell controls movement of molecules in and out of cell?
The cell membrane controls what enters and leaves the cell. There are protein channels within the lipid bilayer (membrane) of the cell. There are carbohydrate chains that hang off of the protein channels that identify each particle around the cell to make sure its what the cell needs, if not it wont let it in.
How are proteins positioned within the membrane?
The protein is anchored into the membrane by its nonpolar region, but the protein remains moblie. To explain it more, the middle section of the protein is made of many nonpolar amino acids. This nonpolar coil fits into the nonpolar interior of the lipid bilayer allowing the protein to float in the membrane.
Why is called the fluid mosaic model?
Fluid refers for the frequent lateral movement of phospholipids within the membrane. Mosaic refers to the collage of intrinsic proteins that stud the membrane.
What are the two proteins found in the cell membrane?
The two main proteins found in the cell membrane are integral proteins and peripheral proteins. Integral proteins are embedded within the membrane and can span across it, while peripheral proteins are located on the surface of the membrane and are not embedded within it. Both types of proteins play important roles in various cellular functions including transport, communication, and cell signaling.
Common route for protein movement within the endomembrane system?
Rough ER to vesicles to Golgi to vesicles to the plasma membrane
Channels within the structure of the cell membrane are composed of....?
Simply stated: ProteinsChannels within the structure of the cell membrane are composed of proteins. A protein that forms an ion channel through a membrane is called a transmembrane protein.

The resistance to an ion's movement across a membrane is determined by?
ion channels within the membrane

What protein powers both the movement of cilia and vesicles within a cell?
Dynein
What is the role of transport and channel proteins within the fluid mosaic of the plasma membrane?
They allow movement of salts and sugars through the plasma membrane
What is the name of the process in which an intracellular protein-containing vesicle fuses with the cell membrane and expels the protein to the outside of the cell?
A protein containing vesicle within a cell fuses with the cell membrane and ejects the protein is called exocytosis. A lysosome eats or ingests a bacterium is called phagocytosis.
When a receptor protein in a cell membrane acts as a enzyme the receptor protein does what?
When a receptor protein acts as an enzyme, the receptor protein activates a second messenger that acts as a signal molecule within the cell. Resources: HOLT Biology Textbook - 9th grade edition Chapter 4, Cells and Their Environment.
