Question 25 What is the process for degrading fatty acids called?
Question 26 What happens to DHAP in glycolysis? DHAP is converted to GAP by triose phosphate isomerase, allowing it to continue through glycolysis. Question 27 Fill in the blanks for glycolysis details:
carbons.
products produce: four ATP.
two ATP, two NADH. Question 28 How many β-oxidation cycles for a 10-carbon fatty acid? A. 4 cycles are required for oleic acid. Each cycle removes two carbon units. ON the final cycle, two acetyl groups are produced. B. There are 5 acetyl-CoA groups produced. Two acetyl-CoA groups on the last cycle. C. There are 4 NADH and 4 FADH molecules produced. One per cycle. 20 carbon A. 9 cycles are required for oleic acid. Each cycle removes two carbon units. ON the final cycle, two acetyl groups are produced. B. There are 10 acetyl-CoA groups produced. Two acetyl-CoA groups on the last cycle C.There are 9 NADH and 9 FADH2 molecules produced. One per cycle.
