What are the 3 inputs of glycolysis?
What are the 3 outputs of glycolysis?
Glucose
NAD+
ATP
pyruvate
NADH
4 ATP (gross), 2 ATP (net)
What happens to NADH at the end of aerobic respiration?
It enters the mitochondria for further oxidation in the ETC
What happens to NADH at the end of anaerobic respiration?
It is used to reduce pyruvate to lactate, regenerating NAD+
Where does the Krebs cycle occur?
Mitochondrial matrix
What are the 5 inputs of the Krebs cycle?
What are the 5 outputs of the Krebs cycle?
Acetyl-CoA
NAD+
FAD
H20
ADP + Pi
CoA
NADH
FADH
CO2
ATP
What are the 3 inputs of oxidative decarboxylation?
What are the 3 outputs of oxidative decarboxylation?
Pyruvate
NAD+
CoA
CoA
NADH
CO2
What is B-oxidation of fatty acids?
Process by which fatty acids are broken down into Acetyl-CoA in the mitochondria, which then enter the Krebs cycle
What are the 4 inputs of fatty acid B-oxidation?
What are the 4 outputs of fatty acid B-oxidation?
Fatty acid
NAD+
FAD
CoA
Acetyl-CoA
NADH
FADH2
CO2
Where does the electron transport chain take place?
Inner mitochondrial membrane
What are the 3 inputs of the electron transport chain?
What are the 3 outputs of the electron transport chain?
NADH
FADH2
O2
H20
ATP
Proton gradient
Where does glycolysis occur?
Cytoplasm
Which process links glycolysis and the Krebs cycle?
Oxidative decarboxylation
In anaerobic respiration, what happens to pyruvate?
Converted to lactate
What is the Cori cycle?
The recycling of lactate from muscle to glucose in the liver
Ammonia produced from the breakdown of amino acids is converted into what?
Urea
What is the primary energy source for the heart?
Fatty acids
What are the 3 substrates of gluconeogenesis?
Lactate
Glycerol
Amino acids
Lactate is converted into glucose in the liver during which process?
Cori cycle
Which GLUT is insulin sensitive?
GLUT-4
