EUKARYOTIC CELLS ORGANELLES - AQA Biology A-Level/AS 5.0 / 5 based on 1 rating ? BiologyCellular processes and structureASAQA Created by: monicaravirajCreated on: 28-10-18 16:33 2734615 Across 1. Produces lysosomes. Secretes carbs. Modifies carbs+proteins - glycoproteins. Produces secretory enzymes and modifies, stores and transports lipids. (5, 9) 4. Double membrane. Inside folded to make cristae and rest is the matrix. The cristae has a large surface area for attachment enzymes for respiration. The matrix contains the enzymes for repiration-Contains ribosomesDNA to control production of proteins (12) 5. Release enzymes to outside of cell by exocytosis. Hydrolyse material ingested by phagocytic cells. Digest worn out organelles so their useful chemicals can be re-used. Contain lysozymes which break down bacterial cell walls by hydrolysis. (9) 7. 70S in prokaryotes and 80S in Eukaryotes. made of two sub-units. (9) Down 2. double membrane. Thylakoids stack up to make granna. Fluid filled matrix is called the stroma. (12) 3. Once molecules modified by Golgi bogy, they transported to the vesicles. Vesicles move to the cell surface and fuse with the cell membrane and release the molecules out of cell. (5, 8) 6. Contains a nucleolus that produces ribosomes. Chromosomes contain DNA/genetic material. Nuclear membrane allows things to enter/exit cell. Nuclear pores allow larger molecules such as messenger RNA to enter/exit. (7)
