Glycolysis
Where does glycolysis happen?
Cytoplasm
Where does pyruvate oxidation happen?
Mitochondrial matrix
What product does the Krebs cycle start and end with?
Oxaloacetate
Where does oxidative phosphorylation take place?
Mitochondrial inner membrane
What is the equation for cellular respiration?
C6H12O6 + 6O2 > 6CO2 + 6H2O + ATP
What is the starting molecule for glycolysis?
Glucose
How many carbons does each pyruvate have?

What are the main products of the Krebs cycle (for one cycle)?
3 NADH, 1 FADH2, 1 ATP, CO2
What does NADH and FADH2 provide to the ETC?
Hydrogens and electrons
Which step of cellular respiration produces the largest amount of ATP?
Electron Transport Chain (oxidative phosphorylation)
Does glycolysis require oxygen?
No it is anaerobic
What is the end product of pyruvate oxidation?
Acetyl CoA
Which two molecules does the Krebs Cycle produce that are useful in the Electron Transport Chain?
NADH and FADH2
What is the importance of oxygen for the ETC?
It's the final electron acceptor.
What is the source of all energy for life?
Sunlight
What are the net products of glycolysis?
2 ATP, 2 NADH, 2 Pyruvate
What product is lost during pyruvate oxidation?
CO2
How many carbons does oxaloacetate have?
4
How many protein complexes are involved in the electron transport chain?
Four
What are the four main steps of cellular respiration?
1. Glycolysis
2. Pyruvate oxidation
3. Krebs cycle (Citric acid cycle)
4. Oxidative phosphorylation
What are the inputs for glycolysis?
Glucose, 2 NAD+, 2 ATP, and 4 ADP + 2 P
How many carbons does Acetyl CoA have?
2
How many times does the Krebs Cycle take place for one glucose molecule? Why?
Two; there are two pyruvate molecules produced from one glucose molecule
