Step by step
Solved in 4 steps
- Summarize the major types of selective cell-cell adhesions. Describe the structure and role of tight junctions in epithelial sheets and adhesion junctions and gap junctions in all tissues. Explain the function of signaling receptors and their ligands in cell-cell interactionsDescribe transmembrane proteins and explain the following roles that they play in the plasma membrane: receptor, enzyme, ion channel, carrier protein, cell-identity marker, and cell-adhesion molecule.Explain the process by which cells are able to communicate with each other.
- Define cell adhesion molecule*For B, look closely/carefully at the molecule being transported. For each label/letter on the diagram above, identify the specific type of cell transport and give an example of a substance/molecule that uses that mode of transport to enter/exit the cell.When the protein integrin (a transmembrane protein in human fibroblasts) is held in place, by covalent bonds to fibronectin and collagen proteins in the interstitial spaces, integrin is exhibiting: restricted movement in the membrane, based on confinement by diffusion barriers restricted movement in the membrane, based on tethering to extracellular molecules restricted movement in the membrane, based on attachment to other cells restricted movement in the membrane, based on anchoring to intracellular proteins unrestricted movement in the membrane, similar to membrane lipids
- Name and define two mechanisms of cellulardifferentiation.Explain how cells respond to external signals, even when those signals cannot enter the cell.Describe the importance of cell-material interactions by providing the series of events upon their contact and the potential outcomes based on material properties.
