2.Manufactures of certain macromolecule such as polysaccharides and pectin that form parts of cell walls.
Details of the receiving and shipping of substances viavesicles:a.Transport vesicles arrive with molecules from the ER and fuse with the cis side of the Golgi.b.The individual cisternae progress through the Golgistructure from the cis to the trans side, carrying andmodifying the contents in the process. This is called cisternae maturation.Ex. Glycoproteins may have their carbohydrate branches modified.c.Transport vesicles containing finished molecules pinch off from the trans face of the Golgi. If the molecules are to be secreted, the vesicles travel to the plasma membrane.Lysosomes: Membranous sacs containing hydrolyticenzymes .They function as digestive compartmentsThey can hydrolyze (break down) proteins, fats, polysaccharides and nucleic acids.They can also use enzymes to break down and recycle organelles and macromolecules within thecell in a process called autophagy.Lysosomes can digest materials taken into the cell from the outside in a process calledphagocytosis. Ex: Amoeba will engulf food particles into a food vacuole, that fill fuse with a lysosome to allow
Lysosome storage diseasesare rare, genetic disorders that affect the function of the hydrolytic enzymes in lysosomes. Waste molecules that would normally be broken down with in the cell build up and cause problems.Tay Sachs disease is caused by a missing or inactive lipid digesting enzyme, that causes the brain to be impaired due to a build up of lipids.Vacuoles: membrane bound sacs with various functions.They are formed from the ER or Golgi.A plant or fungal cell may have many vacuoles.Food vacuolesare formed by phagocytosis.Central vacuolesare large vacuoles found in plants that contain organic compounds and water (sap) They play a large part in the growth ofplant cells.
