Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the molecular structure?Composed of adenine, ribose, and three phosphate groups
2. What is the standard free energy of hydrolysis?Approximately -30.5 kJ/mol
3. What is ATP?ATP is a tiny molecule that stores energy for cells. It has an adenine base, a ribose sugar, and three phosphate groups. When one phosphate bond breaks, it releases energy for the cell.
4. Why does ATP give energy to cells?When ATP breaks a phosphate bond, it releases about 30.5 kJ of energy. This energy powers many cellular activities like moving muscles and pumping ions.

Exergonic Reaction: A chemical reaction that releases energy, often used to drive ATP synthesis.
Endergonic Reaction: A chemical reaction that requires an input of energy, often powered by ATP hydrolysis.
