Cellular respiration is a key concept to understand in biology as it involves obtaining energy from the nutrients organisms eat and the removal of waste products. It is a key biological process which is vital to all life forms, including humans.

In this biology course you will learn about the chemical makeup of the energy that is stored, generally referred to as adenosine triphosphate (ATP), how this molecule works and how it is used in the respiratory process. You will also learn about glucose as it is the main source of energy, and the stages involved in cellular respiration from glycolysis through the Kerb’s cycle to the electron transport chain. You will learn how molecules are split to release energy through oxidization to produce ATP and waste products in the form of water and carbon dioxide.

This biology course will be of great interest to all students who wish to pursue a career in sciences such as biology, biochemistry, medicine, pharmacy or the individual learner who simply wants to learn more about how we convert our food into energy.

After completing this course you will be able to: - Describe ATP, the currency of energy in life forms; - Explain how foodstuffs are broken down into simpler molecules; - Describe how hydrogen is separated out over a series of steps; - Describe how the separation of hydrogen releases energy; - and identify the terminology associated with respiration.
