Final answer:
Fatty acids formed from LPL activity in muscle tissue are broken down into acetyl CoA through beta-oxidation and utilized for ATP production for the energy needs of the muscle. The correct option is A) They are stored as Triglycerides
Step-by-step explanation:
When fatty acids are formed from lipoprotein lipase (LPL) activity in muscle tissue, they are primarily broken down into energy for the body. In muscle cells, fatty acids can undergo a process called beta-oxidation within the mitochondria, where they are converted into acetyl CoA. The acetyl CoA then enters the citric acid cycle, also known as the Krebs cycle, to be oxidized for the production of ATP, which is used by the muscle for its energy demands. Therefore, the correct answer is A) They are broken down into energy for the body.
Fatty acids are a key source of fuel for muscles, especially during prolonged periods of exercise or fasting when glucose levels are low. Muscle cells have the capacity to oxidize fatty acids efficiently, which distinguishes them from adipose tissue where fatty acids are mainly stored as triglycerides for later use. It is important to note that while fatty acids can be converted into acetyl CoA, they cannot be converted back to glucose as this would require a process known as gluconeogenesis, which is not possible for acetyl CoA. The correct option is A) They are stored as Triglycerides
