Because with out energy we wouldn't be moving and we would always be sleeping.
Answer:
The correct option is this: GLUCOSE IS CO-TRANSPORTED WITH Na+, WHICH MOVES DOWN ITS CONCENTRATION GRADIENT INTO THE CELL.
Explanation:
The small intestine is the place, where digested food molecules are absorbed so that they can be transported into the living cells through the blood stream. The glucose molecule is transported into the small intestine by mean of co-transport with sodium ions; this is an example of active transport. This form of transportation across the small intestines prevents the back flow of glucose molecules.

Answer:
Liver, 25-hydroxycholecalciferol.
Explanation:
Vitamin D is a fat soluble vitamin that increases the absorption of phosphate and calcium in the body. Vitamin D2 and D3 are most important for the human health.
The hydroxylation of cholecalciferol occur in the liver in order to be active vitamin D. The first hydroxylation of cholecalciferol produces 25-hydroxycholecalciferol.
Thus, the answer is liver, 25-hydroxycholecalciferol.
All biomolecules could be called carbon-based molecules.
The monomers of DNA are nucleotides.
Cell membranes are made, in part, from phospholipids.
The monomers of of starch are monosaccharides.
Explanation:
Biological macromolecules are giant carbon-based molecules. They are polymers made by complex condensation reactions linking them together.
These molecules are typically produced exclusively by living organisms and this is why they are called biological macromolecules.
They are usually classified as organic compounds for their linkage to living processes.
- It is correct that all biomolecules are carbon-based molecules. They are primarily made up of carbon, hydrogen and oxygen with some other elements.
- Deoxyribo-nuclei Acids are macromolecules that contains all information about the life of an organism. The DNA is located in the nucleus of cells and it is the genetic matter that controls life activities. The basic unit of DNA is the nucleotides.
- Cell membranes are structural component of cells that helps to regulate the movement of materials in and out of the cell. They are made up of phospholipids.
- Monomers of starch are monosaccharides. These are the simplest unit of starch that cannot be further hydrolyzed. They are usually called simple sugars. Examples are glucose and fructose.
