Cells have different uses and functions. There must be differentiation/diversity between cells to form a functional organism.
Hello there buddy,
<span>RNA is able to hydrogen bond with water (otherwise it wouldn't be soluble), but since water is small and prefers to be able to move around freely, these hydrogen bonds are quite unstable. For that reason, RNA forms much more stable bonds with larger, compatible molecules. Among those, different RNA molecules may bind to DNA or proteins to serve some function, while they can also bind complementary strands of RNA.

I hope this helps you!

Answer:
The exergonic reaction of hydrolysis of ATP must be coupled to an endergonic reaction to perform work or to power other reactions.
Explanation:
ATP (adenosin triphosphate) is hydrolized to give ADP and releases energy as follows:
ATP + H₂O ⇆ ADP + Pi + energy
The released energy itself is not used to power biochemical reaction. In order to power other reactions, ATP hydrolysis- a energetically favorable reaction- is coupled to another energetically disfavorable reaction. The linking or coupling is performed through a shared intermediate, which is often a phosphorilated molecule. For example, in the formation reaction of sucrose from glucose and fructose, an intermediate is formated by the transfer of a phosphate group (Pi) provided by ATP hydrolysis. Then, the phosphorilated intermediate (glucose-Pi)- wich is unstable- reacts with fructose in a spontaneous reaction to give sucrose.
