Overview of metabolism

8 videos
1D: You are breathing, your heart is beating, and you are reading this sentence. All these processes would be impossible were it not for the chemical energy produce within our cells. In this tutorial, we will integrate the biology and chemistry of metabolism as we walk you through the electron transport chain and the production of ATP, the ultimate energy currency in our bodies.

Overview of metabolism: Anabolism and catabolism

VIDEO 8:41 minutes
What is the purpose of metabolism? Learn about the two major divisions in metabolism: anabolism (building up) and catabolism (breaking down).  By Jasmine Rana.

ATP hydrolysis mechanism

VIDEO 5:35 minutes

ATP hydrolysis: Gibbs free energy

VIDEO 7:41 minutes
How does ATP provide energy for biosynthesis reactions? Use an understanding of Gibbs Free Energy to understand how ATP is coupled to energy-requiring processes. By Jasmine Rana.

ATP hydrolysis: Transfer of a phosphate group

VIDEO 9:46 minutes
How is ATP coupled to energy-requiring processes? How does the transfer of a phosphate group "fuel" chemical reactions?

Oxidation and reduction review from biological point-of-view

VIDEO 13:29 minutes
Taking a looking at oxidation and reduction in a biological context.

Oxidation and reduction in metabolism

VIDEO 10:07 minutes
How is metabolism similar to a galvanic cell? Apply fundamental principles of electrochemistry to understand the energy harnessed from the oxidation-reduction processes of metabolism.

Electron carrier molecules

VIDEO 10:02 minutes
What are electron carrier molecules? What role do they play in metabolism? Learn how electron carrier molecules capture the flow of electrons from the breakdown of a fuel (e.g. glucose) to produce ATP.
