The Mighty, Mighty, Mitochondrion! Slide 2 Singular = mitochondrion Plural = mitochondria Slide 3 Structure of a Mitochondrion -looks like a worm -has TWO membranes -1 st regular (outer membrane) -2 nd folded up (this one is called the CRISTAE) -Guess what both of these Membranes are made of???? -has a little bit of DNA Slide 4 Illustration of Structure Slide 5 Function of the Mitochondrion -The mitochondrion releases energy from carbohydrates. -carbohydrates get turned into a form of energy called ATP Slide 6 Which cells have mitochondria? -ALL EUKARYOTIC CELLS HAVE MITOCHONDRIA -cells that need more energy have more than others Slide 7 Where is the ATP actually made? -The ATP is made on the folds of the CRISTAE Why do you think they're folded up like that? Slide 8 Why do mitochondria have DNA? Mitochondria have a little bit of DNA, but it's not organized. What does that remind you of? Slide 9 Remembering trick: MITOCHONDRIA = ATP Slide 10 Ribosomes Slide 11 Where do they come from? -Ribosomes are made in the nucleus, and then sent out into the cytosol -They are made of RNA and protein combined together Slide 12 Ribosomes make proteins Slide 13 Remembering Trick: RIBOSOMES = MAKE PROTEINS Slide 14 Endoplasmic Reticulum, a.k.a E.R Slide 15 Structure of the Endoplasmic Reticulum The E.R. is a series of stacked membranes that look like tunnels of balloons. Slide 16 The Function of the Endoplasmic Reticulum -The E.R. helps move materials around the cell. -The Rough E.R. transports proteins to other places after theyre made by the ribosomes. -The Smooth E.R. transports other materials. Slide 17 Remembering Trick E.R.= HIGHWAY Slide 18 The Golgi Apparatus The E.R. transports proteins to the Golgi Apparatus Slide 19 Structure of the Golgi Apparatus The G.A. looks like a bunch of semi- circular balloons stacked up. Slide 20 Function of the Golgi Apparatus -The Golgi Apparatus packages, processes, and polishes proteins. Slide 21 Remembering Trick G.A. = POST OFFICE
