Cellular Respiration
Storyboard Text
- What is the purpose of cellular respiration?
- Cellular respiration is used to generate usable ATP energy in order to support many other reactions in the body. This is how it works
- The first process in Cellular Respiration is Glycolysis in which glucose is split into two three-carbon molecules called pyruvate acid. This process occurs in the Cytoplasm of the cell. At last pyruvate oxidization takes place where pyruvate dehydrogenase converts the three-carbon pyruvate to the two-carbon acetyl-CoA.
- Glucose
- 2 ATP
- 2 ADP
- G3P
- 2 NAD+
- 4 ADP
- 4 ATP
- 2 NADH
- Pyruvate
- FADH2
- FAD
- Inner Membrane
- Outer Membrane
- The next step in the Cellular Respiration process is the Krebs cycle (also. known as the citric acid cycle) which occurs in the Matrix of the Mitochondria. This process starts with 2 pyrivic adic molecules and acetyl coa where they go through the cycle twice producing NADH and FADH2 The catalyst of this is Coenzyme A. The other byproducts of this cycle are CO2 and 2 ATP.
- ATP
- Acetyl CoA
- CO2
- Inner Membrane Space
- NAD+
- NADH
- The next step in Cellular Respiration is the Electron Transport Chain located in the inner membrane of the mitochondria. The NADH and FADH2 from the Krebs cycle help with ATP synthesis.

- FADH2

- Inter Membrane

- NADH
- H+
- Next in the Electron Transport Chain, protons and phosphates gain energy allowing for production of 34 ATP by turning ADP into ATP. Along with this Electrons flow moving H+ to the Inter-membrane

- NADH -- NAD

- Wow that is so cool!
- Yes it is, and heres a diagram to sum it all up.
