Once fatty acids have been split from triglycerides, they undergo a process where they enter circulation and are transported to working muscles where they can be utilized for energy. This is a crucial aspect of how the body mobilizes fat for use during physical activity. Once inside the muscle cells, fatty acids can be oxidized to produce ATP, which is the energy currency the body uses for muscle contractions.

Additionally, fatty acids can also be re-esterified by adipose tissue if there is an excess of them. This process involves the reconversion of fatty acids back into triglycerides for storage, thereby allowing the body to maintain energy reserves. This dynamic relationship between fatty acid utilization and storage is essential for energy balance in the body, especially during periods of physical exertion.

The other options don't accurately reflect the metabolic pathways of fatty acids. Fatty acids are not simply eliminated from the body, nor can they be converted into carbohydrates or directly into glucose in a straightforward manner; while there are metabolic pathways that can convert fats into intermediates used in carbohydrate metabolism, this is not a direct conversion process.
