Final answer:
The correct answer to the student's question is (A) Glucose is transformed into sucrose, as it is not one of the main fates of glucose within body cells. In the body, glucose is catabolized to carbon dioxide and water, converted to lactate, synthesized into glycogen, or converted to acetyl CoA to form body fat, but it is not transformed into sucrose.
Step-by-step explanation:
The question posed is about the four main fates of glucose once it is inside the cells of the body. The options given include glucose being transformed into various other compounds. Which of the following is not one of those fates of glucose?
- A) Glucose is transformed into sucrose.
- B) Glucose is catabolized to carbon dioxide and water.
- C) Glucose is converted to lactate.
- D) Glucose is used to synthesize glycogen.
- E) Glucose is converted to acetyl CoA to make body fat.
After examination of the role of glucose in the body, it is clear that glucose can be catabolized to carbon dioxide and water during respiration, transformed into lactate during anaerobic conditions, stored as glycogen in the liver and muscle cells, or converted into acetyl CoA for the synthesis of fat. However, glucose is not directly transformed into sucrose within the body's cells - as sucrose is a disaccharide consisting of glucose and fructose. Therefore, the correct answer is A) Glucose is transformed into sucrose.
