ATP Practice

Front

Which bond of the ATP molecule is broken in order to release energy?

Back

The bond between the second and third phosphate groups (the terminal phosphate bond) is broken to release energy.

Front

What type of macromolecule is ATP/ADP?

Back

ATP and ADP are classified as nucleic acids.

Front

What is the name of the nitrogenous base that helps make up ATP?

Back

Adenine is the nitrogenous base that is part of ATP.

Front

Which enzyme helps attach a phosphate onto ADP?

Back

The enzyme ATPsynthase helps attach a phosphate group to ADP to form ATP.

Front

What is the function of ATP in living things?

Back

ATP provides energy for cellular processes.

Front

What are the three components of an ATP molecule?

Back

An ATP molecule consists of adenine, ribose (a sugar), and three phosphate groups.

Front

How is ATP regenerated from ADP?

Back

ATP is regenerated from ADP by the addition of a phosphate group, a process catalyzed by ATPsynthase.

Front

What role does ATP play in muscle contraction?

Back

ATP provides the energy required for muscle fibers to contract.

Front

What is the significance of the high-energy phosphate bonds in ATP?

Back

The high-energy phosphate bonds in ATP store energy that can be used for various cellular activities.

Front

How does ATP release energy?

Back

ATP releases energy when the terminal phosphate group is hydrolyzed, breaking the bond and releasing energy.
