1. Energy and Life ATP

2. ATP:  Adenosine triphosphate.  Has unstable phosphate bonds.  Used by cells as an energy source for cellular activity.  Produced mainly from the process of cellular respiration.  Eukaryotic cells which require a lot of energy, will have a lot of mitochondria (site of cell resp.)

5. HOW ATP DOES WORK TYPE OF WORK DESCRIPTION Mechanical  Beating of cilia or flagella  Muscular contraction  Movement Transport  Active transport  Proton Pumps (H+ and Na+/K) Chemical  Endergonic reactions (require energy)  Polymerization (formation of polymers such as carbs, lipids, etc.)
