Active Transport, Endocytosis and Exocytosis, and Cell Size — Homework
Review active transport, bulk transport, and surface-area-to-volume ratio before answering.
- 1.Does active transport require cellular energy? Answer yes or no, and name the energy molecule involved.
- 2.A cube-shaped cell has 2 cm sides. Calculate its surface area (6 x side-squared) and volume (side-cubed).
- 3.Name the process by which a white blood cell engulfs a bacterium, and state whether it is a form of endocytosis or exocytosis.
- 4.Explain, using the surface-area-to-volume idea, why a cell cannot simply keep growing larger indefinitely.
- 5.Explain the key difference between active transport and passive transport in three or four sentences, including at least one real example of each.
