Document Summary
Cell physiology is the study of how cells work together to perform functions in a living organism. Cells are organized in a packed environment thus there are issues with molecules finding each other. This is solved by compartmentalization (using membranes), guided signaling, and micro-domains of signaling. Because of the packed environment, once the proteins find their targets, there is better interaction since the cell components are pushing against each other. Compartmentalization also allows for more efficient modifications (ex. Micro-domains (i. e. lipid rafts) cause other proteins of interest to group together in a targeted location. Majority contains all the genetic information as dna. They are contained in a highly ordered fashion to be easily accessed in specific portions that are needed for cellular use. Rbcs and the cornified cell layer in skin does not have any dna (they have a high turn-over rate and are rapidly replaced by new cells)
