embedded in the membrane? - 🧠 ANSWER ✔✔Double layer of lipids;
2
phospholipids, cholesterol, glycolipids; proteins are embedded
What is the most abundant lipid in the plasma membrane? - 🧠 ANSWER
✔✔phospholipids
The heads of phospoholipids are (Hydrophilic/hydrophobic) - 🧠 ANSWER
✔✔Hydrophilic
The tails of phospholipids are (Hydrophilic/hydrophobic) - 🧠 ANSWER
✔✔Hydrophobic
What are the two types of membrane proteins? - 🧠 ANSWER ✔✔Integral
and Peripheral
What are the most abundant proteins in the membrane? (Most are

,What is a short chain of carbohydrates (sugars) projected out from the
external surface of glycoproteins or glycolipids called? what is its function?
3
- 🧠 ANSWER ✔✔Glycocalyx (Cell Coat); functions in cell to cell binding and
recognition
What cells produce Glycocalyx? - 🧠 ANSWER ✔✔Corneal epithelial surface
cells
Three functions of the Plasma Membrane - 🧠 ANSWER ✔✔1. Barrier
against substances and forces outside cell
2. externally-facing proteins act as receptors and in cell to cell recognition
3. Acts in transport of substances into or out of cell
What type of barrier is the membrane considered? - 🧠 ANSWER
✔✔Selective permeable
What is the Passive Process of movement? - 🧠 ANSWER ✔✔Substances
can pass freely through the lipid bilayer down their concentration gradient.
No ATP needed

, What is Diffusion? - 🧠 ANSWER ✔✔Movement of small uncharged
molecules like oxygen, CO2, and fat soluble molecules across the
4
membrane
What is the Active Process of Movement? - 🧠 ANSWER ✔✔Substances
move against their concentration gradient from a lower to higher
concentration. ATP is needed
What is Active Transport? - 🧠 ANSWER ✔✔Most larger water soluble or
charged molecules, such as glucose, amino acids, and ions are transported
by a pump or carrier and involve the integral proteins
What is Vesicular or Bulk Transport? - 🧠 ANSWER ✔✔Large particles and
macromolecules pass through the membrane by this mechanism.
What are the two types of Bulk Transport? - 🧠 ANSWER ✔✔Exocytosis and
Endocytosis
What is Exocytosis? - 🧠 ANSWER ✔✔Membrane-lined cytoplasmic
vesicles fuse with the plasma membrane and release their contents to the
outside of the cell.
