the liver converts what into glucose? Explain the process of what
happens next... Correct Answer ✔✔-fructose and galactose.
This elevates blood glucose levels, which causes the release of insulin
from the pancreas. With insulin production, glucose is moved out of the
bloodstream into cells in order to meet energy needs.
The body digests ____% of starch within ___ to ___ hours after
ingestion. Correct Answer ✔✔-95%, 1-4 hours
Where does digestion occur and explain the process... Correct Answer
✔✔-Digestin occurs mainly in the small intestine using pancreatic
amylase to reduce complex carbohydrates into disaccharides.
Glycogen Correct Answer ✔✔-Stored carbohydrate energy source found
in the liver and muscles. it is a vital source of backup energy, but is only
available in limited supply.
How does the body maintain glucose levels between meals? Correct
Answer ✔✔-glucose is released through the breakdown of liver glycogen.
DIgestable carbohydrates provide ___ cal/g of energy Correct Answer
