The proetome of a cell determines its ? - correct answer Structure and function. Prokaryotic cell - correct answer Reletively simple sturctures without a nucleus, put into either bacteria/archaea categories, composed of a cell wall and a glycocalyx Eukaryotic cell - correct answer Compartmentalized into organelles and contain a nucleus that houses thier DNA. Cytosol - correct answer Central coordinating region for many metabolic activites of eukaryotic Metabolism - correct answer Sum of all chemical reactions by cells Cytoskeleton - correct answer 3 diffrent types of protein filiments: microtubules, intermediate filiments, and actin filaments.
