BIOLOGY 172 Lecture Notes - Lecture 12: Competitive Inhibition, Citric Acid Cycle, Electron Transport Chain
Document Summary
S4 plants and fungi (cid:523)yeasts(cid:524) don"t have lysosomes. Autophagy and phagocytosis deliver materials to vacuole for degradation (instead of to lysosomes). A vacuole does many of the same things that lysosomes do. This takes place in the mitochondria and the chloroplast. The inner membrane includes all the energy production molecules. Semi-autonomous means that they are a cell within a cell (mitochondria in animals, chloroplast in plants). They have dna (their own genetic material) and ribosomes to make their own proteins. There is an idea that they grew from an endosymbiotic (friendly) relationship. Through evolution, the mitochondria cannot survive without us and vice versa (goes for plants as well) Mitochondria has its own ribosomes which allow it to synthesize its own proteins. Chloroplast are the organelles in plant cells that carry out photosynthesis. Their mitochondria carries out the same activities as in an animal cell. The cytoskeleton is want keeps the cell rigid and intact.
