Document Summary
Lipid bilayer fat molecules pair of tails pact densly and two layers of them. Semi permeable membrane means allows passage of some molecules not allow passage of laeger ones or anions charged particles. Charged particles and larger ones need specific channel built for them. Nucleus hold dna and genetic material to replicate and send infor from one gen to another. Between nuc and membrane is cytoplasm contains is cytosol which is liquid gel and organells that float. Work as powerplants produce energy to drive various processes. Made in mitochondria and sent to various parts of cell. Riosomes units that make proteins translate rna to string of aa to proteins. Seres as post office where difernt chemicals are packaged and addressed to different parts of cells. Waste processing not used digested basic parts. Mediators of vast majority of cell functions. Which parts genetic material expressed as protein result in function. Polypeptide colpases on self and 3d strucuture to become function protein.
