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
