1 Cellular Respiration Its how our cells release energy from food! BrainPOP: Cellular Respiration
2 Do you remember??? What types of organisms do photosynthesis? Why do plants do photosynthesis?What are the reactants (what goes in)?What are the products (what goes out)?Which plant organelle is the site of photosynthesis?How do animals get their energy?How do they get food?Which organelle releases energy from food?
3 Cellular Respiration energy The process by which cells release from glucose (sugar).energyThis process happens in BOTHPLANT and ANIMAL cells!
4 Where do plants and animals obtain glucose? FOOD!Animals get it from the food they eat!Plants get it from the food they make!
5 Glucose is the most common sugar found in food!C6H12O6
6 Besides glucose, what else do cells use for cellular respiration? OxygenHow do we get oxygen?Breathing
8 Two Stages of Cellular Respiration Use yourtextbooks… page 382!Two Stages of Cellular RespirationStage 1:In the cytoplasmStage 2:In the mitochondriaGlucose is broken down into smaller moleculesA small amount of energy is releasedThe smaller molecules react and produce carbon dioxide, water and large amounts of energy.
9 What are the reactants and products of cellular respiration? C6H12O O CO H2O energyglucoseoxygencarbon dioxidewaterenergyIs matter conserved after this chemical reaction?
10 Cellular Respiration Equation This energy is also known as ATP!Reactants (what goes in)Products (what comes out)

14 Exit Slip “P”= Photoysnthesis only “C”= Cellular respiration only DescriptionAnswers1. Releases energy from food2. Makes food energy for the organism3. Performed by autotrophs (plants) only4. Produces carbon dioxide5. Produces glucose and oxygen6. Occurs in the chloroplast7. Occurs in the mitochondrion8. Uses glucose and oxygen9. Uses sunlight, water and carbondioxide10. Performed by both autotrophs (plants) and heterotrophs (animals)CPPCPPCCPC
