**Classification of Molecular Transport Mechanisms** **Instructions:** Classify each example as requiring either diffusion or bulk flow as a mechanism for molecular transport. **Diffusion:** - This section is intended for examples of molecular transport that occur through the process of diffusion. Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration, typically across a cell membrane or within cellular fluids. **Bulk Flow:** - This section is designated for examples that involve bulk flow. Bulk flow refers to the movement of large volumes of fluids, carrying molecules along with them, often driven by pressure differences within biological systems such as blood flow in vessels or air movement in respiratory passages. Note: The image contains two empty boxes under the headings “Diffusion” and “Bulk Flow,” indicating sections to categorize specific examples into these transport mechanisms.
