A starch molecule is formed when many disaccharide molecules are combined. Starch is often produced in plants as a means of storing energy. The two other molecules formed when multiple disaccharide molecules are combined are cellulose and glycogen. The cell walls in plants are made up of cellulose. Glycogen is a carbohydrate energy source.
A disaccharide molecule is formed when two monosaccharide molecules are joined together. Maltose, sucrose and lactose are the most important disaccharides. <span>A monosaccharide molecule is a simple sugar, for example, glucose. </span>
Answer:
b. Fetal Hb binds oxygen more tightly than adult Hb.
Explanation:
This is because Fetal Hb needs to draw oxygen more efficiently from the blood stream of mother which is a very difficult task. The more affinity binds the oxygen from the blood stream that is already bonded with Hb of mother This is the main reasons it has higher affinity than that of an adult Hb.
Additionally, speaking of myoglobin. A myoglobin always has more affinity to bind oxygen that that of a haemoglobin molecule.
It certainly can. In fact, it's preferred because of it's affordability and sturdiness, which make it a perfect material for grave stones.
