Question 1

plasma membrane

Answer 1

is the membrane found in all cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface

Question 2

fluid mosaic

Answer 2

A model that describes the structure of cell membranes

Question 3

selective permability

sell active pir mit ability

selective perm ability

Answer 3

some substances are able to pass through the membrane, while other substances are not able to pass through. The cell membrane is considered to be selectively permeable, since it selects what is able to pass through

Question 4

glycerol

glis ir all

gly cer ol

Answer 4

Each carbon atom of glycerol can be linked to a fatty acid, which will then become a chemical group by itself referred to as “acyl.” If all three carbons of glycerol have reacted with a fatty acid, we will obtain a triacylglycerol (TAG), also named triglyceride.

Question 5

membrane protein

Answer 5

proteins being associated or attached to the membrane of a cell or an organelle inside the cell. They are divided into peripheral and integral proteins

Question 6

peripheral protein

Answer 6

a protein that is found temporarily attached to the cell or mitochondrial membrane.

Question 7

integral protein

Answer 7

membrane protein (IMP) is a type of membrane protein that is permanently attached to the biological membran

Question 8

glycoprotein

Answer 8

molecules that comprise protein and carbohydrate chains that are involved in many physiological functions including immunity. Many viruses have glycoproteins that help them enter bodily cells, but can also serve to be important therapeutic or preventative targets

Question 9

glycolipid

Answer 9

lipids with a carbohydrate attached by a glycosidic (covalent) bond
