Document Summary
Cell was discovered by robert hooke and realized that thin slices of cork resemble as a honeycomb, so he called them cell. s. Nucleoplasm- substance forming the contents of a nucleus. Maintains the structural integrity of the cell-barrier function, regulates cell interactions and transduces extracellular signals. Passive transport is transport with gradient that does not require the energy of. Active transport is transport against gradient that does require the energy of atp. Largest organelle in a cell that consists of sheets, tubules and three-way junctions. Rough er has an associated ribosome which function in primary synthesis/folding including glycosylation and disulfide bond formation. Smooth er functions in lipid synthesis and calcium storage. It is a disease that involves the chronic lung infections ad is fatal. Disease mutations cause cftr protein to misfold in the er. Multiple stacks in each cell, form a single ribbon. Polarized; a cis face that receives vesicles from the er and a trans face that releases mature vesicles.
