Cellular Respiration Its how our cells release energy from food! BrainPOP: Cellular Respiration

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?

Cellular Respiration energy The process by which cells release from glucose (sugar). energy This process happens in BOTH PLANT and ANIMAL cells!

Where do plants and animals obtain glucose? FOOD! Animals get it from the food they eat! Plants get it from the food they make!

Glucose is the most common sugar found in food! C6H12O6

Besides glucose, what else do cells use for cellular respiration? Oxygen How do we get oxygen? Breathing

energy oxygen food breathing

Two Stages of Cellular Respiration Use your textbooks… page 382! Two Stages of Cellular Respiration Stage 1: In the cytoplasm Stage 2: In the mitochondria Glucose is broken down into smaller molecules A small amount of energy is released The smaller molecules react and produce carbon dioxide, water and large amounts of energy.

What are the reactants and products of cellular respiration? C6H12O6 + 6O2 6CO2 + 6H2O + energy + + + glucose oxygen carbon dioxide water energy Is matter conserved after this chemical reaction?

Cellular Respiration Equation This energy is also known as ATP! Reactants (what goes in) Products (what comes out)
