The biological macro molecule is CARBOHYDRATE.
Carbohydrates are made up of just three elements, which are carbon, hydrogen and oxygen, all joined together in a ringed structure. The number of carbon a carbohydrate has determined the class of carbohydrate under which it is grouped. The particular one we are given in this question has five carbon, so it is a pentose sugar.
Carbohydrate are the major source of energy in the living cells.
The correct answer is 12680.3
D) Active transport. In this process, dissolved molecules move across plasma membrane from a lower to higher concentration. Because they move against the concentration gradient, an energy from the cell is required.
