What is glycolysis
|
- occurs in cytosol
- coverts glucose into 2 pyruvate - no O2 -10 separate reactions |
|
|
What are the three phases of glycolysis?
|
1. Energy Investment (glucose to fructose, 2 ATP used)
2. Cleavage of a six-carbon sugar into 2 three-carbon sugars. 3. Energy Generation |
|
|
How much energy is put in during glycolysis?
|
2 ATP
|
|
|
How much energy do you get out (and in what form) during glycolysis?
|
2 NADH, 4 ATP, 2 pyruvate
|
|
|
Net Input of Glycolysis
|
glucose, 2NAD, 2ADP, 2Pi
|
|
|
Net output of Glycolysis
|
2 NADH, 2 ATP, 2 pyruvate, 2H+, 2 H2O
|
|
|
What is the purpose of Citric Acid Cycle
|
- in mitochondria
- complete oxidation of carbon atoms of acetyl groups in acetyl CoA |
|
|
Inputs of Cirtric Acid Cycle
|
acetyl CoA
|
|
|
Outputs of Citric Acid Cycle
|
3 NADH, 1 GTP, 1 FADH, 2 CO2
|
|
|
How is Citric Acid Cycle related to electron transport and ATP production?
|
- NADH from citric acid cycle is passed through electron chain turning it into NAD+, and keeping the cycle going
- NADH and FADH used to produce ATP via oxidation phosphorylation |
|
|
Where does acetyl CoA come from?
|
- pyruvate and fatty acids
|
|
|
How much energy in and out and in what form for Citric Acid Cycle?
|
-
|
|
|
What is the net reaction (Citric Acid Cycle)?
|
pyruvate + GDP + Pi + FAD + 4 NAD+ yeilds 3 CO2 + GTP + FADH + 4 NADH + 4 H+
|
|
|
linear pathway
|
-
|
|
|
circular pathway
|
-
|
|
|
What are alternatives to glycolysis and the citric acid cycle?
|
-
|
|
|
intermediates
|
-
|
|
|
gluconeogenesis
