The answer is: A. True
Complex sugars or polysaccharides are composed of basic units called monosaccharides that are linked via glycosidic bonds. Glycosidic bond is formed through condensation reactions (water is released) that occur between a hydroxyl (OH) oxygen atom on one sugar and the α-anomeric form of C-1 on the other. There are are two types of glycosidic bonds:
- 1,4 alpha ( the OH is below the glucose ring)
- 1,4 beta glycosidic bonds (the OH is above the glucose ring)
Amylase is an enzyme that breaks down starch into smaller glucose molecules, it act on α-1,4-glycosidic bonds and it works in mouth where the digestion begins (salivary amylase) . Maltase breaks down maltose into glucose; sucrase, breaks down sucrose into glucose and fructose; and lactase, which breaks down lactose into glucose and galactose work in small intestine and also act on α-1,4-glycosidic bonds.
Answer:
b. carb (sugars)
Explanation:
plants make glucose through photosynthesis
Answer:
Option (2) and (3).
Explanation:
Cancer is the uncontrolled division of the cell that might results in the loss of apoptosis in the cells. The cancer cell shows the property like angiogenesis and loss of contact inhibition.
Both the hereditary factors like mutations in some gene and environmental factors like any mutagen may inhibit the process of the cell division. Both these factors mainly inhibits the gene that are responsible for the regulation of the cell cycle like p53, Rb.
Thus, the correct answer is option (2) and (3).
