Fluid Mosaic Model (plasma membrane) – composed of lipids, proteins, and carbohydrates in a bilayer arrangement. o Not static, always moving o Functions: ▪ Protection and maintenance of cell shape (lipids & proteins) ▪ Formation of a selective transport system (proteins) ▪ Cellular metabolism (proteins/enzymes) ▪ Cell-to-cell recognition and interaction, including ability to bind ligands (hormones, cytokines, neurotransmitters) medications, and even pathogens (proteins & carbohydrates) ▪ Cell-to-cell adhesion (proteins) • Structure of the cell along with their functions o Cytoplasm – physical space that the cell occupies; main site for protein synthesis and degradation o Organelles: ▪ Nucleus – contains thEndoplasmic Reticulum o A system of vesicles or membranes that run throughout the cell and transport material both within the cell and out of the cell.Fluid Mosaic Model (plasma membrane) – composed of lipids, proteins, and carbohydrates in a bilayer arrangement. o Not static, always moving o Functions: ▪ Protection and maintenance of cell shape (lipids & proteins) ▪ Formation of a selective transport system (proteins) ▪ Cellular metabolism (proteins/enzymes) ▪ Cell-to-cell recognition and interaction, including ability to bind ligands (hormones, cytokines, neurotransmitters) medications, and even pathogens (proteins & carbohydrates) ▪ Cell-to-cell adhesion (proteins) • Structure of the cell along with their functions o Cytoplasm – physical space that the cell occupies; main site for protein synthesis and degradation o Organelles: ▪ Nucleus – contains thEndoplasmic Reticulum o A system of vesicles or membranes that run throughout the cell and transport material both within the cell and out of the cell.
