Lysosomes and Diseases • • Lysosomal storage diseases are hereditary – They interfere with other cellular functions – Examples: Pompe’s disease, _____________________disease – Both cause a build up of substances in the lysosome – Fatal diseases Non heritable lysosomal diseases – Silicosis & Asbestosis – _______________________ (secreted lysosomal enzymes alter cell surface) – Rheumatoid _____________________________(secretion of high levels of lysosomal enzymes digest extracellular matrix) Plant cells contain a large central ______________________ – Functions in the general maintenance of the cell – Fluid-filled organelle with lysosomal and _________________________functions – Stores amino acids, sugars, ___________________________ – 50-90 % of cell volume – Protists may have contractile vacuoles The organelles of the endomembrane system are interconnected structurally and functionally • ENERGY-CONVERTING ORGANELLES – Mitochondrion – Chloroplast • • Chloroplasts – Chloroplasts are found in plants and some _______________________ – Chloroplasts convert solar energy to the chemical energy in sugars: _______________________________ – Why the world is green: chlorophyll Mitochondria – Carry out cellular respiration • A process that uses chemical energy in food to make for _____________________ cellular work • Adenosine triphosphate- the energy source • These reactions require ____________________ • Origins of Mitochondria and Chloroplasts: _________________________________________ theory • May have evolved from ancient bacteria • Mitochondria and chloroplasts resemble bacteria – Have own DNA, _________________________________ – Divide on their own and same in size
