BIO 130 CHECK YOUR UNDERSTANDING 1. When the body is in an absorptive state, glucose is readily … oxidative phosphorylation leads to ATP formation. As the postabsorptive state begins, glucose levels drop, and there is a corresponding drop in insulin levels. total cholesterol level, HDL level, and triglyceride level. After a few days, however, ketone bodies are created from fats and serve as the preferential fuel source for the heart and other organs, so that the brain can still use glucose. During the absorptive state, the body digests food and absorbs the nutrients. The gluconeogenesis that has been ongoing in the liver will continue after fasting to replace the glycogen stores that were depleted in the liver. Related Questions. If there were no method in place to store excess energy, you would need to eat constantly in order to meet energy demands. D) glucose supplied from glycogen. The empty statement: The empty statement consists of a single semicolon. The extra glycogen serves as a reservoir for glucose, which serves as the main fuel molecule for increased cellular respiration, resulting in more available ATP. After ingestion of food, fats and proteins are processed as described previously; however, the glucose processing changes a bit. If glycogen stores are depleted during fasting, alternative sources, including fatty acids and proteins, can be metabolized and used as fuel. A) Only glucose metabolism occurs. A post-absorptive state differs from an absorptive state. As starvation continues, fatty acids and triglyceride stores are used to create ketones for the body. C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP energy. E. gluconeogenesis is suppressed. Which hormone drives the most pathways in the absorptive state?
