BIOL 2070 FINAL EXAM QUESTIONS WITH CORRECT
ACTUAL QUESTIONS AND CORRECTLY WELL DEFINED
ANSWERS LATEST 2024 – 2025 ALREADY GRADED A+
what are the different intracellular compartments - (answers)- Membrane
enclosed organelles
- Protein sorting
- Vesicular transport
- Secretory pathways
- Endocytic pathways
Phagocytosis - (answers)A type of endocytosis in which a cell engulfs large
particles or whole cells
How does vesicular transport work? - (answers)- Transport Vesicles Carry Soluble
Proteins and Membrane Between Compartments
- Vesicle Budding Is Driven by the Assembly of a Protein Coat
- Vesicle Docking Depends on Tethers and SNAREs
Exocytosis - (answers)a vesicle fuses with the plasma membrane, releasing its
content to the cell's surroundings
Endocytosis - (answers)extracellular materials are captured by vesicles that bud
inward from the plasma membrane and are carried into the cell.

clathrin - (answers)a protein that plays a major role in the formation of coated
vesicles
secretion - (answers)Secretory proteins are released from the cell by exocytosis
• There are two pathways
- The Constitutive exocytosis pathway provides a steady stream of proteins and
lipids to the plasma membrane and cell exterior—no signal sequence is required
- The Regulated exocytosis pathway operates in secretory cells— large amounts of
required substance is stored in vesicles and released in response to an
extracellular signal
Pinocytosis - (answers)A type of endocytosis in which the cell ingests extracellular
fluid and its dissolved solutes.
receptor-mediated endocytosis - (answers)The movement of specific molecules
into a cell by the inward budding of membranous vesicles containing proteins
with receptor sites specific to the molecules being taken in; enables a cell to
acquire bulk quantities of specific substances.
calcium signalling - (answers)the use of calcium ions (Ca2+) to communicate and
drive intracellular processes often as a step in signal transduction.
scaffold proteins - (answers)organize groups of intracellular signaling molecules
into signaling complexes
