Questions and Answers

What is the primary purpose of cellular respiration?

To release oxygen into the environment
To break down ATP into smaller molecules
To produce adenosine triphosphate (ATP) for energy (correct)
To convert nutrients into waste products

What is the role of molecular oxygen (O2) in cellular respiration?

It is converted into ATP directly
It is a waste product released during respiration
It inhibits the process of respiration
It is the most common oxidizing agent in cellular respiration (correct)

Which molecule is commonly used by animal and plant cells in cellular respiration?

What is cellular respiration?

Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy. Signup and view all the answers

What are the two types of respiration and how do they differ?

The two types of respiration are aerobic, requiring O2, and anaerobic. Aerobic respiration requires oxygen, while anaerobic respiration does not require oxygen. Signup and view all the answers
