Hello class ! We are learning about cellular respiration today .
yay
What did Mrs.C just said ? What is that
2. Krebs Cycle
Alright class , let's begin our notes
cellular respiration has 3 stages
3. Electron transport chain
C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy)
Does anyone know what is cellular respiration?
Cellular respiration is the conversion of carbohydrates (glucose) into ATP energy for the cell in the presence of oxygen.
1. Glycolysis - occurs in the cytoplasm of the cell
glucoseC6H12O6
2 pyruvate C3H4O3
Glycolysis
2 ATP
4 ATP
2-4 ATP
2 NAD+
2 NADH
- Pyruvate is broken down into carbon dioxide in a series of reactions.- occurs in Matrix of the mitochondria- also known as aerobic, must requires oxygen to process
2 ATP molecule🡪 used for energy6 NADH molecules🡪 Electron carriers to ETC2 FADH2 molecule🡪 Electron carriers to the ETC CO2🡪 Byproduct
input : 2 AcetylCoA ( 1 per cycle)
2-4 ATP
matrix of mitochondria
- Occurs in the folds of the Inner Membrane of the Mitochondria .- are molecules that transport electrons and temporarily store energy. NAD+ and FAD are empty carriers. Electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion.
