Energy is measured in Energy is measured in caloriescalories
One calorie heats one gram of One calorie heats one gram of water one degree Celsius water one degree Celsius
Food energy is measured in Food energy is measured in CaloriesCalories– One Calorie = 1 kilocalorie (1000 One Calorie = 1 kilocalorie (1000

Cells release the energy in glucose Cells release the energy in glucose to make to make ATPATP molecules molecules
Adenine Ribose 3 Phosphate groups
ATP Molecule
What would ADP look like?
The breakdown of glucose to produce energy in the form of ATP is called Cellular Respiration.
Occurs in the mitochondria of alleukaryotic cells (plant & animal)
Comparing photosynthesis and Comparing photosynthesis and respirationrespiration
Photosynthesis and respiration are Photosynthesis and respiration are oppositeopposite processes processes
Photosynthesis Photosynthesis removesremoves carbon carbon dioxide from airdioxide from airCellular respiration puts it Cellular respiration puts it backbackPhotosynthesis Photosynthesis puts puts oxygen into airoxygen into airRespiration Respiration removesremoves it itPhotosynthesis Photosynthesis capturescaptures energy and energy and converts it into glucoseconverts it into glucoseRespiration Respiration releasesreleases the energy the energy from glucosefrom glucose
