glucose + galactose =
enzyme that helps sugar for degradation
maltose
sucrose
lactose
Lactase
- helps glucose to be utilized or be absorbed inside the cell
- produced by - inhibits the production of insulin (only hormone that suppresses glucose)
- produced by - hormone in glycolysis
- produced by
- INSULIN
- beta cells of islets of langerhan - SOMATOSTATIN
- delta cells - GLUCAGON
