ATP

What does ATP stand for?

Adenosine Triphosphate

What is cell respiration?

The controlled release of energy in the form of ATP from organic compounds in cells

Where is ATP synthesized in muscle cells?

In the mitochondria.

What is necessary for muscle contraction?

Energy in the form of ATP.

What happens to ATP when it loses a phosphate molecule?

It is converted into ADP (Adenosine Diphosphate).

What is the role of ATPase in energy release?

ATPase breaks the last high-energy bond in ATP

What type of energy is released when ATP is broken down?

Explosive energy as a result of a catabolic reaction.

How long can the stored ATP in muscles typically last during intense exercise?

For about 3-5 seconds.

What process must occur for exercise to continue when ATP stores are low?

ATP must be regenerated from ADP using energy from other sources.

What is the purpose of ATP synthase in the energy cycle?

It facilitates the reconnection of an inorganic phosphate with ADP to resynthesize ATP.
