<span>- they both deal with molecules that travel down/with a concentration gradient without using energy - facilitated diffusion uses protein transporters to move substances across a membrane - the process of simple diffusion occurs only in prokaryotes while facilitated diffusion is seen only in eukaryotes - simple diffusion doesn't require energy, but facilitated diffusion requires a source of ATP - simple diffusion can only move material in the direction of a concentration gradient, while facilitated diffusion moves materials with and against a concentration gradient</span>
NUCLEUS IS CALLED CONTROL CENTER OF THE CELL BECAUSE IT PERFORMS TWO MAIN PRINCIPAL FUNCTIONS: Controls cellular activities through directing synthesis of particular proteins and enzymes. The control center of the cell is the nucleus in Eukaryota cells. The nucleus contains genetic material in the form of DNA. The DNA gets split, resulting in new cell production.

Explanation:feedback inhibition is define as a process in which the end product of a control enzyme that help synthesis the end product.
It refers to the individual cell of our body that can control or inhibit certain actions.its the action taken by our body to regulate certain natural processes. It refers to the process of using of a reaction produce to limit its own further production.
