Question

Which one of the following statements is not true about fatty acid synthesis?

During fatty acid synthesis, acetyl and malonyl (carboxylated acetyl) groups are transferred from CoA to the Acyl Carrier Protein (ACP), which attaches them to fatty acid synthase.
Which of the following is not a step catalyzed by fatty acid synthase during fatty acid synthesis?

1 points Save Answer Question 7 What important product is generated (charged) in the oxidative phase of the pentose phosphate pathway? NADPH O fructose 6-phosphate (F6P) O glyceraldehyde 3-phosphate (GAP) O glucose 1-phosphate (G1FP) O glucose 1 points Save Answer Question 8 Which one of the following statements is not true about fatty acid synthesis? O Isoprene provides the carbon used for fatty acid synthesis O The growing fatty acid is bound to an Acyl Carrier Protein (ACP) O Each cycle lengthens the acyl group by two carbon atoms. O Each round of lipogenesis includes two reductions and a dehydration O Malonyl CoA adds carbon to the acyl group in each round 1 points Save Answer Question 9 During fatty acid synthesis, acetyl and malonyl (carboxylated acetyl) groups are transferred from CoA to the Acyl Carrier Protein (ACP), which attaches them to fatty acid synthase Which of the following is not a step catalyzed by fatty acid synthase during fatty acid synthesis? O Reduction of the -carbonyl to a hydroxyl group O Acetyl CoA formation from the cleavage of citrate O Reduction of a double bond to a single bond O Condensation of an acyl-ACP and malonyl-ACP O Dehydration of hydroxyl group to a double bond

Explanation / Answer

Multiple choice

7. Product formed in the oxidative phase of the pentose phosphate pathway is,

NADPH

8. False statement for fatty acid synthesis would be,

Each round of lipogenesis includes reduction and dehydration

9. During fatty acid synthesis, acetyl and malonyl (carboxylated acetyl) groups are transferred from CoA to the Acyl Carrier Protein (ACP), which attaches them to fatty acid synthase.

the step which is not catalyzed by fatty acid synthase during fatty acid synhtesis would be,

acetyl Coa formation from cleavage of citrate
