BIOL 2404 Chapter 3 2025/2026 Exam
Questions with 100% Correct Answers |
Latest Update
Differentiation - 🧠ANSWER ✔✔Process by which a cell becomes
specialized for a particular function.
Composite Cell - 🧠ANSWER ✔✔-Also called a 'typical' cell
-Major parts include:
nucleus, cytoplasm and cell membrane
Cytoplasm - 🧠ANSWER ✔✔Consists of organelles, with specific functions,
suspended in a liquid called cytosol.
Cell Membrane - 🧠ANSWER ✔✔- Outer boundary of the cell
,- Maintains integrity of cell
- Bilayer is permeable to lipid-soluble substance, but impermeable to water-
soluble substances
- Consists mainly of lipids and proteins, with some CHO
- Embedded on the surface of the membrane: Cholesterol, Proteins, and
Glycoproteins/Glycolipids
Selectively permeable - 🧠ANSWER ✔✔Regulates entry and exit of
substances; charged particles can not pass through without help: Na+, K+,
Cl-; Uncharged or very small molecules move freely through the
membrane: O2, H2O, CO2
Cholesterol - 🧠ANSWER ✔✔A type of fat made by the body from saturated
fat; stabilizes membrane, helps keep it impermeable to water-soluble
substances
Selectins - 🧠ANSWER ✔✔Coat white blood cells and anchor them by
providing friction
Integrins - 🧠ANSWER ✔✔Direct white blood cells through capillary walls
toward infection sites
, Cytoplasm - 🧠ANSWER ✔✔- Consists of networks of membranes and
organelles suspended in cytosol.
- Cytosol + Organelles
Cytosol - 🧠ANSWER ✔✔Fluid portion of cytoplasm
Organelles - 🧠ANSWER ✔✔Tiny sold structure with specific functions in the
cell.
Cytoskeleton - 🧠ANSWER ✔✔A supporting, branching framework of protein
rods and tubules.
Ribosomes - 🧠ANSWER ✔✔- Composed of protein and RNA
- Free in cytoplasm or on RER
- Provide structural support and enzyme activity to link amino acids in
protein synthesis
- free ----> intracellular proteins
Endoplasmic Reticulum (ER) - 🧠ANSWER ✔✔- Membrane-bound sacs,
canals, vesicles
- Tubular transport system
