ATP ENERGY BIOLOGY I ATP ATP Adenosine Triphosphate

ATP= ENERGY BIOLOGY I

ATP �ATP = Adenosine Triphosphate �Is used to store and release energy �Is made when organisms break down food (carbohydrates) �Has three parts 1. Adenine 2. Ribose sugar 3. Three phosphate group � Think of ATP as a fully charged battery

ATP STRUCTURE 3 phosphate groups Adenine Ribose Sugar

ADP �ADP= Adenosine Diphosphate �Has three parts 1. Adenine 2. Ribose sugar 3. Two phosphate group � Think of ADP as a half charged battery

ADP STRUCTRE 2 phosphate groups Adenine Ribose Sugar

ADP + 1 phosphate = ATP When the extra phosphate is added to ADP energy is stored ( the half charged battery is now fully charged)

ATP- 1 Phosphate = ADP + ENERGY When a phosphate group is removed from ATP energy is released. (the fully charged battery is now half charged)

ENERGY ATP is used to store energy but not for long periods of time (lipids are used to energy for long periods of time) Cells use the energy from carbohydrates to add phosphate to ADP to keep creating ATP when needed.

Uses for ATP It helps provide energy for active transport It helps to move organelles inside the cell It is used to transmit nerve impulses It is used to contract muscles It is used by plants during photosynthesis to make glucose
