Cellular Transport and Molecular Biology Quiz

Active transport requires energy input to move molecules across a cell membrane.

Lysosomes are responsible for breaking down cellular waste and toxins.

Ribosomes are responsible for protein synthesis within cells.

Osmosis is the movement of water across a semipermeable membrane.

Exocytosis is not a type of endocytosis; it is the process of expelling materials from cells.

Simple diffusion involves the passive movement of molecules from high to low concentration without requiring energy.

The sodium-potassium pump moves ions against their concentration gradient, requiring energy.

Active transport necessitates energy input for moving molecules across the cell membrane.

Carrier proteins transport molecules across the cell membrane.

Mitochondria are not part of the endomembrane system.

Endocytosis involves the use of vesicles to transport large molecules into the cell.

The plasma membrane does not participate in energy production within cells.

DNA replication occurs during the synthesis (S) phase of the cell cycle.

Aquaporins facilitate the movement of water across cell membranes.

Microtubules transport vesicles and organelles within the cell.
