Lesson 7: Cellular Respiration

Stage 1: Glycolysis

No C02 Emitted

+2 Phospates = 2 ATP

2 pyruvates used for stage 2

Substrate level phosphorylation

Breaking off of a phosphate from substrate to product generating ATP

Stage 2: Pyruvate Oxidation and Citric Acid Cycle

Pyruvate looses a carbon to form C02

Electrons reduce NAD+ to form NADH

A coenzyme joins the 2 carbon compound to make Acetyl CoA

This enters the Citric Acid Cycle

FAD is reduced to form FADH2

2 ATP are created for a total of 4 ATP from substrate level phosphorylation

Stage 3: Oxidative Phosphorylation

Electron transport proteins located in the inner membrane of a mitochondria pump facilitate the flow of H+

Fermentation (Anaerobic)

Alcohol Fermentation

Produces C02 ex. bubbles in your Champagne :beer_mugs:

Lactic Acid Fermentation

Does not produce C02
