Document Summary
Notes for 85 are in lecture one notes. Notes for 93-97 are in lecture three notes. Eukaryotic cells contain intracellular membrane-bound compartments that segregate di erent molecules and metabolic reactions. We think so as they emerge from the golgi apparatus. For decades, debate has occurred if microbodies are a part of the endoplasmic reticulum. Main organelle involved in the removal of compounds generate within cells. Microbodies contain oxidative enzymes involved in the digestion of unwanted molecules. Compartmentalisation of these enzymes and their reactive products protects other cell components from degradation. Contain a variety of degradation enzymes lack dna, ribosomes and internal membrane elaborations seen in chloroplasts and neutral ph (di erent to lysosomes) Contain oxidative enzymes that generate hydrogen peroxide and the enzyme catalase. Can be peroxisomes or glyoxysomes depending on which enzymes they contain. Peroxisomes oxidise amino acids and uric acid (mainly animal cells)
