Introduction about organells of the eukaryotic cell1. What is the eukaryotic cell?
Organells of animal and plant cells• Those organelles bounded by a single membrane are covered first, followed by the three types that have a double membrane— the nucleus, mitochondrion, and chloroplast.
Organells of animal and plant cells Nucleus• Nucleus contains a eukaryotic cell’s genetic library.• Contains nucleous and chromatin.
Endosomes Endosomes Take Up Soluble Macromolecules from the Cell Exterior
Lysosome• Lysosomes are membrane-bound vesicles that contain hydrilytic enzymes.• Digestive organell where macromolecules are hydrolyzed.• Tay-Sachs disease and Gaucher disease.
Endoplasmic Reticulum (ER) Rough ER :Secreted proteins and membrane proteins are synthesizedSmooth ER : important in lipid synthesis
Peroxisome• Peroxisomes are small organelles containing enzymes that oxidize various organic compounds without the production of ATP.
Golgi Apparatus• Organelle active in synthesis, storing and secretion of cell products.• The Golgi apparatus forms a part of the cellular endomembrane system.
Plant Vacuoles• Storage sites for ions and nutrients.
Mitochondrion• Mitochondria produce ATP using energy stored in food molecules.• Breaks down sugar (glucose) molecules to release energy.• Site of aerobic cellular respiration.
Chloroplast • Chloroplasts absorbs light energy to conserve free energy in the form of ATP and reduce NADP to NADPH.
