Video: Cellular Respiration

Cellular respiration is the process of taking Oxygen and Glucose and turning it into ATP, energy for the body. In this lecture, that is the topic I deal with. It’s important to understand this process in order to understand how the body functions, because in order to do everything you do, energy is needed. This is different from the process of Photosynthesis in Plants because, unlike plants, we cannot produce our own energy from the energy obtained from the Sun.

This is part Chapter 9 in the textbook Biology: The Dynamics of Life, which is the chapter on Energy of the Cell.

Outline

  • What is Cellular Respiration?
  • The three stages of Cellular Respiration
  • Fermentation
  • The two Phases of Photosynthesis

    Hi Samuel! I was just a little bit confused regarding the number of ATP, NADH and FADH molecules produced by the Krebs Cycle and the number of ATP molecules produced by the ETC because in my textbook it says, the citric acid cycle produces 2 ATP, 8 NADH, H+ and 2 FADH2 per glucose molecule and, for the ETC, my textbook says The ATP-synthase produces 32 ATP per glucose molecule whereas you said the ETC produces 36 ATP. Could you help me out a little there please?

    Cheers!

    Hey Leslie your videos are great! Just want to clarify something though, I always thought that the Electron transport Chain could produce 32/34 ATP whilst Krebs=2ATP and Glycolysis=net 2 ATP. In your video you have said the ETC produces 36 ATP. Could you please explain this? Thank you!

    This video has helped me greatly understand the cellular respiration process. The diagrams in my book only served to confuse me. This video broke it down so that I can understand.
