Cellular Respiration

What is respiration?

What is respiration? When we breathe oxygen into our lungs and release carbon dioxide. CO2 (Carbon Dioxide) Oxygen

Where does the Oxygen go?

Where does the Oxygen go? Oxygen diffuses into the blood.

Where does the Oxygen go? Oxygen diffuses into the blood. Blood travels around the body.

Where does the Oxygen go? Oxygen diffuses into the blood. Blood travels around the body. Oxygen diffuses into the cells.

Plants also respire! They take in oxygen and “breathe” out CO2

What happens in the cell? Food and oxygen combine to form energy. Sugar + Oxygen  ENERGY + Carbon Dioxide + Water +  + +

What happens in the cell? Food and oxygen combine to form energy. Sugar + Oxygen  ENERGY + Carbon Dioxide + Water C6H12O6 + O2  ATP + CO2 + H2O +  + +

Where does cellular respiration happen in the Cell? Cellular respiration happens inside the mitochondria in the cell.

Respiration in the Cells Cellular respiration - when our cells use oxygen to break apart sugar in order to release energy (ATP). It is the opposite reaction of Photosynthesis (Photosynthesis backwards is Cellular Respiration!)

Photosynthesis Cellular Respiration Sunlight + carbon dioxide + water  sugar (food) + oxygen _______ + _______ + _______  _______ + _______ Cellular Respiration Sugar (food) + oxygen  energy + carbon dioxide + water _______ + _______  _______ + _______ + _____

Photosynthesis Cellular Respiration Same!!! Sunlight + carbon dioxide + water  sugar (food) + oxygen Energy + CO2 + H2O  Glucose + O2 Cellular Respiration Sugar (food) + oxygen  energy + carbon dioxide + water Glucose + O2  ATP + CO2 + H20

Photosynthesis Cellular Respiration Sunlight + carbon dioxide + water  sugar (food) + oxygen _______ + _______ + _______  _______ + _______ Cellular Respiration Sugar (food) + oxygen  energy + carbon dioxide + water _______ + _______  _______ + _______ + _____

ATP and Sunlight are just different forms of Energy Photosynthesis Sunlight + carbon dioxide + water  sugar (food) + oxygen Energy + CO2 + H2O  Glucose + O2 Cellular Respiration Sugar (food) + oxygen  energy + carbon dioxide + water Glucose + O2  ATP + CO2 + H20 Same!!! ATP and Sunlight are just different forms of Energy

Do plant cells do cellular respiration too? YES!! Why? Plants produce glucose (energy storing sugar) through photosynthesis, but they still need to make that sugar usable for the cell. They use the process of cellular respiration to make usable energy (ATP) for the cell. This process also happens in the mitochondria of the plant cells.
