9-1 Cellular Respiration Food provides living things with the chemical building blocks they need to grow and reproduce

Chemical Energy and Food calorie = the amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius. Glycolysis = the first process that begins the breakdown of glucose to release energy.

Overview of Cellular Respiration Processes that releases energy by breaking down glucose and other food molecules in the presence of oxygen. 6O2 + C6H12O6 6CO2 + 6H2O + ATP (Reactants) (Products) Oxygen + glucose is converted to carbon dioxide + water + energy

Where does Cellular Respiration Take Place? Mitochondria

Chloroplast & Mitochondria Both plants and animals need energy, so they both have mitochondria! Only plants have chloroplast!

Fermentation Fermentation = releasing energy from food molecules to produce ATP without oxygen Anaerobic = “not in air” Two types Alcoholic fermentation produces alcohol Lactic acid fermentation produces lactic acid
