Daily Quiz - ATP

Vocabulary flashcards covering the structure of ATP, its conversion to ADP, and the rechargeable battery analogy from the Daily Quiz.

ATP Molecule

A biological molecule consisting of three primary components: adenine, ribose, and three phosphate groups.

Adenine

One of the three parts of an ATP molecule, consisting of a two-ring nitrogenous base bonded to ribose.

Ribose

The five-carbon sugar molecule in ATP that connects the adenine base to the phosphate groups.

Phosphate Group

A chemical group in ATP found in a series of three; breaking the bond of the terminal group releases energy.

ADP (Adenosine Diphosphate)

The molecule resulting from the removal of the third phosphate group (Structure D) from an ATP molecule.

Bond between C and D

The specific chemical bond between the second and third phosphate groups that must be broken to convert ATP into ADP.

ADP Rechargeable Battery Analogy

The comparison stating that ADP is 'uncharged' when energy is released and a phosphate is detached, and becomes 'charged' again when the cell obtains glucose and reattaches the phosphate.
