Living things need energy to carry out their life processes. Animals get this energy from food through a process called cellular ______________________. The first stage, glycolysis, occurs in (anaerobic / aerobic) conditions, or without oxygen. The second stage, called the Krebs cycle, and the third stage, electron transport, require the presence of oxygen, and are therefore (anaerobic / aerobic).

Yabine is studying energy from food in her nutrition class. She learns that fats, proteins, and carbohydrates can store different amounts of energy because they have different chemical ____________________ and different numbers of energy-storing chemical bonds. Carbohydrates and proteins each release (4000 / 9000) calories per gram when burned, and fat releases about (4000 / 9000) calories per gram. The molecule containing the most energy-storing chemical bonds is (carbohydrate / fat / protein).
