PPT-Ribosomes & Endoplasmic Reticulum

Ribosomes Made of ribosomal RNA and protein Synthesized by nucleolus of cell Proteins from cytoplasm are brought to nucleus and made with rRNA into large and small subunits of ribosomes Subunits leave the nucleus and assemble into ribosomes. LIPIDS . hydrophobic or amphipathic small molecules. What are the main classes of . lipids?. Where are they found in the cell?. Where did they come from?. Lipids Classes. Fatty acids. Free (toxic unless esterified). Prepared by:. . Jomar M. Urbano. 2SED-SC. Ms. . Aimie. M. Aquino. Professor. Learning Objectives:. Describe Smooth Endoplasmic Reticulum (SER) in terms of structure.. Functions of . Smooth Endoplasmic Reticulum . Finishing proteins and creating lipids since the beginning of life.. The Rough Endoplasmic Reticulum. The function of the rough endoplasmic reticulum is to finish making the proteins.. Process: the rough endoplasmic reticulum wraps around the protein creating protection.. . By Dr. . Vani. Gupta.

Prokaryotic cells. Simplest cells. No membranes around their nuclear material (DNA and RNA, genetic material). Prokaryotes include bacteria and some pond scum. Pete McGee. What are Ribosomes?. Found in every cell. Protein Synthesizers of the cell. Located on the Rough ER and in the cytoplasm in eukaryotic cells and move freely in prokaryotic cells. They are a combination of RNA and proteins . Plant and Animal Cells. - Looking Inside Cells. Cell Wall. Plants only. Outer layer, rigid, strong, stiff; made of cellulose.
