Question
Fats are usually metabolized into ace CoA. However, fats can be converted to glucose. How is this possible? People concerned about their weight must pay attention not only to triacylglyceride intake but also to the consumption of carbohydrates. Carbohydrates can be converted to glycogen in liver, muscle and some other tissues, but only 5% of the energy stored in the body is stored as glycogen. What happens to most carbohydrates that are consumed in excess of caloric need? What is the difference between a synthetase and synthase? Provide an example of each to illustrate this difference.Explanation / Answer
6a. Yes the fats can be converted to Glucose by the procedure known as Gluconeogenesis. This normally happens when body doesnt receive Glucose e.g, during starvation. Fats are metabolised and channeled towards formation to Glucose.
6b. The excess of glucose consumed are channeled towards formation of Glycogen and stored as mentioned above. Secondly the glucose are eliminated in the urine if it crosses threshold level. Excess of glucose is also stored as fat by lipogenesis.
6c. Synthetase is a ligase that synthesizes new molecules by combining different compounds and hence utilizes a higher energy source such as ATP.
While Synthase is a lyase that breaks chemical bonds to form new structures via double bonds so it utilizes less energy.
