What is the primary purpose of cellular respiration?

To convert chemical energy from nutrients into ATP

What is the characteristic of the reactions involved in cellular respiration?

They break large molecules into smaller ones, producing large amounts of energy

Which molecule contains the energy produced during cellular respiration?

Adenosine triphosphate (ATP)

Which organism can switch between aerobic and anaerobic respiration?

Both plants and animals

What are the common nutrients used by animal and plant cells in respiration?

Sugar, amino acids, and fatty acids

What is the most common oxidizing agent used in cellular respiration?

Molecular oxygen (O2)

What is the preferred method of pyruvate production in glycolysis?

Aerobic respiration

What is the terminal electron acceptor in the electron transport chain during aerobic respiration?

Oxygen

What is the main energy carrier produced in the citric acid cycle?

NADH

What is the approximate maximum yield of ATP molecules per oxidized glucose molecule during cellular respiration?

38

Which type of metabolism is up to 15 times more efficient than anaerobic metabolism?

Aerobic metabolism

In which organelle do the post-glycolytic reactions take place in eukaryotic cells?

Mitochondria

Which type of organisms are able to continue with anaerobic respiration, yielding more ATP by using inorganic molecules other than oxygen as final electron acceptors?

Methanogens

What is the chemical energy stored in ATP mainly used for?

Driving processes requiring energy

What does aerobic respiration require in order to create ATP?

Oxygen (O2)

Test your knowledge of the process of cellular respiration, which involves the oxidation of biological fuels to produce adenosine triphosphate (ATP) and release waste products. Explore the metabolic reactions that take place in the cells of organisms to convert chemical energy from nutrients into ATP.
