Design an image of a cell membrane with the following features: 1. **Shape**: Structure resembling a curved rectangular shape with a wavy edge, representing a flexible membrane. 2. **Color**: Use shades of teal for the membrane structure, with gradient effects to show depth. 3. **Surface Details**: Add small oval structures in varying sizes on the surface to represent proteins uniformly distributed instead of circular dots. 4. **Protein Channels**: Incorporate two large, rectangular protein channels in a darker shade of teal, extending through the membrane. 5. **Receptors**: Remove the specific receptor design; instead, create simple stick-like shapes extending from the surface in different orientations. 6. **Chemical Signals**: Include random small green and orange lines (without specific shapes) representing signaling molecules approaching the membrane. Ensure there are no brand references in the design.
