General Biology - ATP-ADP Cycle

Energy

Can exist or be stored in many forms such as ligh, heat, electricity, and chemical bonds in chemical compounds

bonds

Cells use energy that is stored in the ______ of certain organic molecules

Adenosine Triphosphate

ATP stands for?

Adenosine Diphosphate

ADP stands for?

ATP

Is a molecule that transfers energy from the breakdown of food molecules to cell processes

• Adenine

• Ribose

• Triphosphate

The Structure of ATP

A nitrogenous base

Adenine

A sugar

Ribose

Three Phosphate Groups

Triphosphate

ATP

This is the fully charged battery

ADP

This is the used or “dead” battery

cellular respiration

It gets this energy from the food you eat (like glucose), through a process called ___________

• Exergonic

• Endergonic

The Coupled Reactions:

Exergonic

• Energy-Releasing

• Produces ATP

Endergonic

• Energy-Requiring

• Required ATP

Hydrolysis

• It is a chemical reaction in which a molecule of water breaks one or more chemical bonds in another compound
