Answer: solar energy in the rays of sunlight
Explanation:
Answer: The Adenosine triphosphate is the molecule that provides energy to all the living structures like plants, animals and human beings. Energy is required for all the vital processes of the body.
The ATP molecule consists of three components. The sugar lies at the centre (ribose sugar that is found in the RNA).
Both sides of the sugar is attached by two different components. One side of the sugar is attached by the base(adenine) and the other side of the sugar is attached by the phosphate group.
This phosphate molecule is the most important part for the activity of ATP.

The main function of viagra is to relax the muscles of the blood vessels in some areas of the body. It is used for the treatment of erectile dysfunction and for high blood pressure. The component of viagra is a competitor to the enzyme PDE5, breaking down cGMP. In the penis, blood is trapped, which results in the erection being maintained. When cGMP levels decrease, the concentration of calcium ions increases, causing smooth muscle contraction.
Explanation:
Helicases are used separate strands of a DNA double helix or a self-annealed RNA molecule using the energy from ATP hydrolysis, characterized by the breaking of hydrogen bonds between annealed nucleotide bases. They also function to remove nucleic acid-associated proteins and catalyze homologous DNA
gyrase is an enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase is a class of enzyme called topoisomerases that are involved in the control of topological transitions of DNA.
