Control of Fatty Acid Synthesis vs. Oxidation correct answer: When Insulin is HIGH --> fatty acid synthesis occurs When Glucagon is HIGH --> lipolysis, fatty acid B-oxidation, ketogenesis occur **These never happen at the same time! Lipolysis correct answer: Process of releasing free fatty acids from triacylglycerols stored in the adipose IN THE FASTED STATE Steps of lipolysis correct answer: 1) Hormone Sensitive Lipase: activated by glucagon and epinephrine TAGs are hydroly...
