Chapter 4 cells: the working units of life. 4. 1 cells provide compartments for biochemical reactions: cell theory was the first unifying theory of biology, cells are the fundamental units of life, all organisms are composed of cells, all cells come from preexisting cells. In prokaryotic cells ribsomes float freely in the cytoplasm: the nucleus is usually the largest organelle, site of dna and dna replication, dna transcription to rna. Inner membrane: extensive folds called cristae, to increase surface aea ribsomoes: eukaryotic cells got mitochondira from englufing prokaryotic cells. Learning catalytics review: peripheral protein most easily removed in lab experiment. Ion channel receptors- gated ion channels, change thier 3d shape when ligand binds: the actelycholine receptor, a ligand gated sodium channel, binds actlycholine to open the channel and allow na to diffuse into the. Lecture 8: cells: the working units of life. Other plastids: chromoplasts make and store pigments in flowers and fruit, leucoplasts store macromolecules such as starch.
