Cellular Respiration
Four metabolic pathways
-
In eukaryotes, pyruvate is transported into the mitochondrial matrix
-
-
-
-
- Oxidative phosphorylation
-
-
-
-
-
-
-
-
-
2 ATP hydrolyzed to create fructose-1,6 bisphosphate
-
-
Two glyceraldehyde-3-phosphate molecules broken down into two pyruvate molecules – produces 2 NADH and 4 ATP
-
3.Citric Acid Cycle
-
Series of steps releases 2 CO2, 1 ATP, 3 NADH, and1 FADH2

respirations
anaerobic respiration
Fermentation
But glycolysis uses up NAD+ and makes too much NADH under anaerobic conditions (dangerous situation)
Many organisms can only use O2 as final electron acceptor, so under anaerobic conditions, they need a different way to produce ATP, like using glycolysis
