During starvation, the body uses fatty acids as an alternative energy source. The tissues that primarily utilize fatty acids during this period are:<br /><br />1. **Liver**: The liver plays a central role in metabolizing fatty acids to produce energy. It breaks down fatty acids through a process called beta-oxidation, generating acetyl-CoA, which then enters the Krebs cycle to produce ATP.<br /><br />2. **Muscle**: Muscle tissue, particularly skeletal muscle, also utilizes fatty acids for energy. During periods of fasting or starvation, muscle tissue increases its uptake of fatty acids and uses them as an energy source.<br /><br />3. **Myocardium**: The heart muscle (myocardium) relies heavily on fatty acids for energy production. Fatty acids are a crucial energy source for the heart, especially during prolonged periods of low glucose availability.<br /><br />Red blood cells and nervous tissue are less likely to use fatty acids as an energy source during starvation. Red blood cells primarily rely on glucose for energy, and nervous tissue (including the brain) prefers glucose and ketone bodies over fatty acids due to the blood-brain barrier's limitations on fatty acid transport.<br /><br />So, the correct answers are:<br />- Liver<br />- Muscle<br />- Myocardium
