Answer:
Step-by-step explanation:
Key Points
When blood sugar levels drop, glycogen is broken down into glucose -1-phosphate, which is then converted to glucose-6-phosphate and enters glycolysis for ATP production.
In the liver, galactose is converted to glucose-6-phosphate in order to enter the glycolytic pathway.
Fructose is converted into glycogen in the liver and then follows the same pathway as glycogen to enter glycolysis.
Sucrose is broken down into glucose and fructose; glucose enters the pathway directly while fructose is converted to glycogen.
Key Terms
disaccharide: A sugar, such as sucrose, maltose, or lactose, consisting of two monosaccharides combined together.
glycogen: A polysaccharide that is the main form of carbohydrate storage in animals; converted to glucose as needed.
monosaccharide: A simple sugar such as glucose, fructose, or deoxyribose that has a single ring.
