Cell structure relies on what 4 factors? - Matter, energy, organization, and information What are the 2 categories all forms of life based on cell structure? - Prokaryotes and Eukaryotes. The proetome of a cell determines its ? - Structure and function. Prokaryotic cell - Reletively simple sturctures without a nucleus, put into either bacteria/archaea categories, composed of a cell wall and a glycocalyx Eukaryotic cell - Compartmentalized into organelles and contain a nucleus that houses thier DNA. Cytosol - Central coordinating region for many metabolic activites of eukaryotic Metabolism - Sum of all chemical reactions by cells Cytoskeleton - 3 diffrent types of protein filiments: microtubules, intermediate filiments, and actin filaments.
