1) An integrin is an integral membrane protein in the plasma membrane of cells. This plays a role in the attachment of a cell to the extracellular matrix (ECM) and to other cells, and in signal transduction from the ECM to the cell. Explain how is the structure of integrins reflective of this function?
2) In a cell with a resting membrane potential what is the distribution of K+, Na+, and Ca2+ ions (more extracellular or intracellular). Describe.
