Which is a key component of the energy molecule atp?

The key component of the energy molecule, ATP is the ribose.

Explanation:

The ATP molecule is formed by one Adenosine (Adenine + Ribose) and three Phosphate molecules. The bonds that keep the second and third phosphate radicals trapped in the ATP are very energetic. Thus, every time the third phosphate comes loose from the set, energy will release to hold it together with ATP. The chemical bonds between two of the ATP phosphates are graphically represented by the ~ (tilde) symbol.

Ribose is the main component of this system, besides being the largest, where the bonds are established.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
