What is the difference between lipids and carbohydrates

Simple carbohydrates (sugar, glucose, fructose etc) are the main source of immediate energy. That is, they are metabolized easily and quickly. All our cells can use glucose for energy, so once it is metabolized and reaches the blood stream it can travel to other cells and tissues. However, lipids are good for storage.

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
