Cellular Respiration

Cellular Respiration Who? All eukaryotic cells Purpose? Convert food (such as glucose) into ATP 1 glucose = 36 ATP Exothermic reaction: reaction that releases heat

Step 1: Glycolysis Where? In cytoplasm What happens? Mitochondria Glucose C6H12O6 C C ATP ATP C C En-zyme C C C C C Where? In cytoplasm What happens? A) Glucose (from our food) is broken down B) 2 ATP molecules released for use by the cell C) Broken pieces of glucose enter mitochondria

Step 2: Kreb’s Cycle Where? Inner mitochondria layer What happens? ATP ATP Mitochondria En-zyme ATP CO2 C C CO2 C CO2 Energy molecule ATP CO2 C CO2 C En-zyme CO2 C Where? Inner mitochondria layer What happens? A) Enzymes break apart the glucose fragments B) 2ATP & CO2 created C) Energy molecules sent to fluid interior of mitochondria

Step 3: Electron Transport Chain ATP ATP ATP Mitochondria P O2 En-zyme ADP ATP O2 Energy molecule ATP ATP ATP ATP ADP P ADP O2 P P O2 ADP O2 Where? Interior mitochondria fluid What happens? Mitochondria takes in oxygen (aerobic) Enzymes + Energy molecule + O2 bonds ADP + P to create…. 32 total ATP’s

Kobe Kuiz Which molecule is the energy molecule of cells? Which types of organisms perform cellular respiration? Where does glycolysis occur? What is broken down during glycolysis? What is created as a result of glycolysis? Where is aerobic respiration performed? Name the 2 stages of respiration that take place in the mitochondria. Which waste gas is created by the Kreb’s cycle? How many ATP molecules are made during glycolysis? Kreb’s cycle? Electron transport chain? In total?
