All cells have an outer plasma membrane that regulates not only what ... to align side-by-side to form broad sheets (Figure 1). Glycerophospholipids are by far the most abundant lipids in cell ...

Similar to a small cut that heals itself after a short time, individual cells in our body suffer "wounds" in their protective ...

This is important because most signaling molecules are either too big or too charged to cross a cell's plasma membrane (Figure 1). Not all receptors exist on the exterior of the cell. Some exist ...

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller ...

A schematic of a polymer electrolyte membrane hydrogen-oxygen fuel cell is shown in Figure 1. Figure 1. Hydrogen-oxygen PEM fuel cell. Hydrogen molecules dissociatively adsorb at the anode and are ...
