BiologyBiological molecules, organic chemistry and biochemistryA2/A-levelOCR Created by: JiyaThomasCreated on: 22-12-17 00:02 Cell Wall Made up of protein called peptidoglycan (polymer of amino acids and sugars) Also called murein 1 of 4 DNA Similar to DNA present in eukaryotes Packaged more tightly and supercoiled (so more compact) Genes present on the chromosomes are grouped into operons (where several genes are switched on and off at the same time) 2 of 4 Ribosomes 70S ribosomes Smaller than eukaryotic ribosomes (80S - forms more complex protiens) Relative size: Dependant on rate at which they settle or form sediment in solution 3 of 4 Flagella Not the 9+2 arrangement like in cilia Filament attached to cell by the basal body Rotated by the molecular motor Energy to rotate provided by ATP Molecular motor causes hook to rotate - resulting in the filament moving in a whip-like manner and propelling the cell 4 of 4
