Answer:
the backbone of DNA contains deoxyribose, where as the backbone of RNA contains ribose.

Explanation:
Scientists didnt belive that there are cells untill robert hooke (1665). He observed the cells in a cork slice with the help of a PRIMITIVE microscope
Leeuwenhoek (1674), with the help of an improved microscope, discovered free living cells in pound water for the first time.
It was robert brown in (1831) who discovered the nucleus in the cell.
Purkinjie in 1839 coined the term 'protoplasm' for the fluid substance of the cell.
THE CELL THEORY, that all plants and animals are composed of cells and that the cell is the basic unit of life, was presented by two biologists, schleiden (1838) and schwann(1839). The cell theory was fuether expanded by virchow (1855) by suggesting that all cells aris form PRE-EXISTING cells. With the discovery of the electron microscope in 1940,it was possible to observe and understand the complex structure of the cell and its various organelles.
Well, thats the history of the discovery of cells.
The endoplasmic reticulum bound enzyme that hydrolyzes glucose-6-phosphate to glucose in liver is: glucose-6-phosphatase.
Glucose-6-phosphatase (G6Pase), an enzyme found mainly in the liver and the kidneys, plays the important role of providing glucose during starvation. Unlike most phosphatases acting on water-soluble compounds, it is a membrane-bound enzyme, being associated with the endoplasmic reticulum.
Liver cells contain a membrane bound enzyme called glucose-6-phosphatase for glycogenolysis by glucagon especially during starvation when free glucose is required. As glucagon enters the liver cells it activates the enzyme glucose-6-phosphatase which then acts on glucose-6-phosphate and hydrolyzes it. As glucose-6-phosphate is hydrolyzed, it results in the formation of a phosphate group and a free glucose. The free glucose thus formed is transported from the liver cell to other tissues by specific glucose transport membrane protiens.
