Cellular Metabolism Flashcards
Where does glycolysis take place?
Cytosol of the cell
What are the entering substrates of glycolysis?
Glucose and other monosaccharides
What is the net ATP production of glycolysis?
2 ATP directly per molecule of glucose (anaerobically)
What is the coenzyme production of glycolysis?
2 NADH , 2 H⁺ (aerobically)
Which is the reduced form of the coenzyme: NAD⁺ or NADH?
NADH
What is the final product of glycolysis under aerobic conditions?
Pyruvate
What is the final product of glycolysis under anaerobic conditions?
Lactate
What are the entering substrates of Krebs cycle?
Acetyl coenzyme A
Where does the Krebs cycle take place?
Mitochondrial matrix (inner compartment of mitochondria)
What is the net ATP production of Krebs cycle?
1 GTP (directly), which can be converted in ATP
What is the coenzyme production of the Krebs cycle?
3 NADH + 3 H⁺ and 1 FADH₂
What are the final products of the Krebs cycle?
2 CO₂ for each acetyl coenzyme A, and other intermediates
What is the net reaction for the Krebs cycle?
Acetyl CoA + 3 NAD⁺ + FAD + GDP + Pi + 2 H₂O > 2 CO₂ + CoA + 3 NADH + 3 H⁺ + FADH₂ + GTP
What are the entering substrates of oxidative phosphorylation?
Hydrogen atoms obtained from NADH + H⁺ and FADH₂ and molecular oxygen (1/2 O₂)
Where does oxidative phosphorylation take place?
Inner mitochondrial membrane
