Aerobic Cellular Respiration class notes.notebook Intro to Cellular Respiration Jan 1612:16 PM Remember Photosynthesis? 6CO2 + 6H2O C6H12O6 + 6O2 What happens to the glucose? In the plant: used to build cell walls used to make ATP (energy) this is called Respiration... C6H12O6 + 6O2 6H2O + 6CO2 + ATP Who else does this? Feb 36:04 PM 1 Aerobic Cellular Respiration class notes.notebook We (animals) do! We need glucose to make ATP (energy), also. When animals eat, their food is broken down into monomer form. One of these monomers is glucose. C6H12O6 + 6O2 6H2O + 6CO2 + ATP During Cellular Respiration if oxygen is present aerobic respiration will occur. Location: mitochondria of a cell. O O Examples of organisms that do aerobic respiration are animals and plants. If oxygen is NOT present then anaerobic respiration will occur. Location: cytoplasm of a cell. Jan 163:22 PM O O Aerobic Cellular Respiration Jan 1612:16 PM 2 Aerobic Cellular Respiration class notes.notebook Let's take a closer look at a mitochondrion to see what is involved with Aerobic Cellular Respiration.... 1) Matrix: the inner space of the mitochondria. Also home to the first rxn in Aerobic Respiration. 2) Cristae: 1. 2. 3. 4. the folds of the inner membrane. 3) Inner membrane: home to the last reaction in Aerobic Respiration. 4) Outer membrane PS: Which types of cells have mitochondria? Plants and animals!!! Jan 163:33 PM Aerobic Cellular Respiration involves.... Electron Transport Glycolysis Three Steps: 1) Glycolysis is an anaerobic step so it takes place in the cytoplasm of the cell. 2) The Kreb Cycle is the 1st aerobic step and it takes place in the matrix of the mitochondria. 3) The Electron Transport Chain is the 2nd aerobic step and it takes place in the inner membrane of the mitochondria. Jan 163:47 PM 3 Aerobic Cellular Respiration class notes.notebook 1) Glycolysis Oxygen Jan 163:38 PM Glycolysis is the first step in cellular respiration and does not require oxygen to break glucose apart. This step takes place in the cytoplasm, outside the mitochondria. Glucose (C6H12O6) is broken down into (2) Pyruvic Acid molecules (3Carbon each). The H+ from the glucose is released and picked up by an electron carrier called NAD+ (NADH) Some of the oxygen from glucose will make its way to the mitochondria. (4) ATP are created when glucose is broken down. However, (2) ATP are used to break down glucose, so (2) ADP +Pi are created. So... only (2) ATP are left when Glycolysis is finished. Jan 164:25 PM 4 Aerobic Cellular Respiration class notes.notebook 2) The Kreb Cycle Oxygen CO2 Jan 164:22 PM The Kreb Cycle is the first step in aerobic respiration. If oxygen is present after glycolysis, then some of the products of glycolysis will enter the mitochondria and begin aerobic respiration. Oxygen and the Pyruvic Acid molecules pass into the matrix of the mitochondria. Pyruvic Acid is broken apart by an enzyme, then the carbons are combined with the oxygen to form carbon dioxide. CO2 is a waste product for animal cells so it is released from the cell. Plants, however, can use the CO2 for photosynthesis. (1) ATP is created from each of the (2) Pyruvic Acid molecules. The Kreb Cycle creates a total of (2) ATP when it is completed. Jan 164:47 PM 5 Aerobic Cellular Respiration class notes.notebook 3) Electron Transport Chain Oxygen Electron Transport Chain ADP + P H 2O Jan 164:23 PM Electron Transport Chain the second step in aerobic respiration and the last step overall. This step creates the most ATP! This last step occurs in the inner membrane of the mitochondria and uses the H+ from glycolysis and oxygen left over from the Kreb Cycle. The H+, that was carried over on NADH, will combine with oxygen to form H2O. As water is being created, energy is being released and building up in the membrane. This energy will create ATP from ADP + Pi, which is found in the cell. This last step will end up producing (34) molecules of ATP from the one glucose molecule! http://vcell.ndsu.nodak.edu/animations/etc/movieflash.htm Jan 164:56 PM 6 Aerobic Cellular Respiration class notes.notebook Let's Review..... oxygen Total Amount of ATP Created during Aerobic Respiration was 38 ATP Jan 164:57 PM 6 O2 + C6H12O6 6 CO2 + 6 H2O + Energy 1) Glycolysis Reactants: C6H12O6 2 ATP Products: 2) The Kreb Cycle Reactants: Oxygen 2 Pyruvic Acid NADH Products: NADH oxygen Found: Reactants: oxygen 2 Pyruvic Acid 2 ATP 3) Electron Transport Chain Products: CO2 H2O 2 ATP 34 ATP Found: Found: Matrix Inner Membrane Cytoplasm Jan 164:57 PM 7 Aerobic Cellular Respiration class notes.notebook Respiration Roadmap 2a.
