1.2 Cell Structure and Function Flashcards
How do materials enter and exit through the cell membrane…
The cell selects which materials go in and out the cell membrane
Helps regulate homeostasis by “controlling” entry and exiting of certain molecules…
The membrane
Makes up the Membrane Structure…
Phospholipids, proteins, and cholesterol
Used to represent what is difficult to actually see…
Scientific Model
Acts as hands to a blind person in the Cell to Cell Recognition…
Glycolipids and Glycoproteins
Communicates with the environment around them by using their “hands” (Glycolipids and Glycoproteins) to identify molecules and other cells…
Cell-to-Cell Recognition
Vital to tissue formation…
Cell-to-Cell-Recognition
Cells are said the be ________ structures…
Selectively Permeable
Make up the majority of the membrane…
Phospholipids
Amphipathic molecules…
Phospholipids and Proteins
There is a hydrophilic and hydrophobic component…
Amphipathic
“Water loving”…
Hydrophilic
“Water fearing”…
Hydrophobic
Two types of proteins that are present in the membrane…
Integral and Peripheral
Completely run through the bi layer from the inside to the outside…
Integral
