ch.9 intermediary metabotism Flashcards
What is the first step of glucose oxidation?
Glycolysis – Glucose is converted to pyruvic acid, producing 2 ATP and 2 NADH2.
What is the second step of glucose oxidation?
Krebs Cycle – Pyruvic acid is converted to acetyl-CoA, which releases 6 NADH2, 2 FADH2, and 2 ATP.
What is the third step of glucose oxidation?
Oxidative Phosphorylation – NADH2 and FADH2 are used to produce ATP. NADH2 makes 3 ATP per molecule, and FADH2 makes 2 ATP per molecule.
How much ATP is made from 1 molecule of glucose?
38 ATP are produced (before considering transport costs).
How much ATP does glycolysis contribute to the total?
Glycolysis produces 2 ATP and 2 NADH2 (which equals 6 ATP).
How much ATP does the Krebs Cycle contribute?
The Krebs cycle produces 2 ATP, 6 NADH2 (which equals 18 ATP), and 2 FADH2 (which equals 4 ATP).
What is the total ATP produced after all three steps?
38 ATP is made after the complete oxidation of glucose, but 2 ATP are used for transport of NADH2 from glycolysis, reducing the total to 36 ATP.
How many ATP does 1 NADH2 produce?
1 NADH2 produces 3 ATP.
How many ATP does 1 FADH2 produce?
1 FADH2 produces 2 ATP.
What are the water-soluble vitamins?
Vitamin B-complex
Vitamin C
What are the fat-soluble vitamins?
Vitamin A
Vitamin D
Vitamin E
Vitamin K
Which vitamin is needed for blood clotting and is produced in the large intestine?
Vitamin K
