Cellular Respiration Quiz

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).

• respiration
• photosynthesis
• fermentation
• digestion

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).

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 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

Which BEST 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

Cellular respiration is balanced by photosynthesis; the two processes work together to maintain the cycling of carbon and oxygen among Earth systems. What describes the roles of carbon dioxide and water in these two processes?

• Carbon dioxide and water are the reactants of both processes.
• Carbon dioxide and water are the products of both processes.
• Carbon dioxide is a reactant of photosynthesis; water is a reactant of cellular respiration.
• Carbon dioxide and water are the reactants of photosynthesis and the products of cellular respiration.
