Document Summary

Theme 1 : the structure of the cell. Module 1 : the composition and structure of membranes. Some of these cells are potentially harmful but are contained or managed by our immune system to keep them under control. E. g. staphylococcus hemolytic resides on skin, harmless if on surface but pathogenic if inside the body (infection leads to activation of immune system. E. g. bacteroids thetaiotaomicron predominant intestinal bacteria, makes enzymes useful in breaking down ingested plant materials (oat, fiber) Unit 2 : phospholipids are the building blocks of membranes. Cells are made up of 4 classes of biological molecules: cell : membrane bound structure containing macromolecules, nucleic acids (dna & rna) Make up the hereditary material of the cell.
