Living things need energy to carry out their life processes.
Animals get this energy from food through a process called cellular (a) . The first stage, glycolysis, occurs in (b) 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 (c)

anaerobic
aerobic
fermentation
photosynthesis

Fats, proteins, and carbohydrates can store different amounts of energy because they have different chemical (a) and different numbers of energy-storing chemical bonds. Carbohydrates and proteins each release (b) calories per gram when burned, and fat releases about (c) calories per gram. The molecule containing the most energy-storing chemical bonds is (d) .

In cellular respiration, energy is trapped in the form of ATP, which is used for cellular work, and acts as a “currency” for energy transfers within a cell.
Which everyday item functions in a way similar to ATP?
an electric generator, because it produces electrical energy from a fuel the power to run cell processes
a pump, because it moves molecules from one side of a membrane to another
a rechargeable battery, because it can store energy and then release it
an electric motor, because the charge difference spins the ATP, which allows for cellular work
tagsHS-LS1-C-4 - 4. Multiple Choice
Which one of the following describes the process of aerobic cellular respiration?
a process that uses nitrogen molecules from the air to make nitrogenous compounds in living things
a process of energy conversion that releases energy from food in the presence of oxygen, forming new compounds
a process of energy conversion that captures light energy and transforms it into chemical energy
a process of energy transfer that converts liquid water into water vapor
