BABS1201 Lecture Notes - Lecture 3: Endomembrane System, Nucleoid, Microfilament
Document Summary
Nucleolus inside nucleus is the site of ribosome production. Chromatid - inside the nucleus but outsider the nucleolus - it is the total accumulation of the genetic material of the cell. Endoplasmic reticulum surrounds the nuclear envelope - ribosomes are attached to it hence creating the name rough endoplasmic reticulum. No ribosomes attached - smooth endoplasmic reticulum - responsible for lipid and carbohydrate production. Transport vesicles - pick up/carry the protein e. g amylase to the golgi apparatus. Golgi apparatus - package, modify, sort the crude of the proteins. From the golgi apparatus, another transport vesicle will transport the protein across the cell membrane. Identify characteristic structures of eukaryotic and bacterial cells and describe their basic functions. Prokaryotes: lack true nucleus, bacteriea and archae. Fimbriae - attachment structures on the surface of some prokaryotes. Nucleoid - region where the cells dna is located (not enclosed by a membrane)
