During each cycle of beta-oxidation, what happens to the carbon atoms of the fatty acid? Release of free fatty acids from adipose tissue is increased by which hormones? From which source can acetyl CoA be obtained for fatty acid synthesis? How do de novo synthesis and oxidation of fatty acids differ? What coenzyme is required for fatty acid synthesis? Which compound is required by the enzyme thiokinase for activating fatty acids? What is the route of citrate conversion in the mitochondria? Read more

Understand the Problem

The questions are asking about the biochemical processes related to fatty acid metabolism, particularly focusing on beta-oxidation and fatty acid synthesis, as well as the roles of specific enzymes and coenzymes involved in these pathways.

More Information

During beta-oxidation, two carbon atoms are removed as acetyl CoA. Hormones such as glucagon and epinephrine increase fatty acid release. Acetyl CoA for synthesis is derived from citrate. The synthesis occurs in cytosol, while oxidation is mitochondrial. NADPH is the coenzyme for synthesis.

Tips

Common mistakes might include confusing the biological locations of processes and the specific roles of coenzymes.
