ADP and ATP
- Structure
- ADP
- Two Phosphate groups
- Ribose sugar
- Adenine base
- ATP
- Adenine base
- Ribose sugar
- Three phosphate groups
- Uses
- Active Transport
across membranes
- Provides energy for carrier
proteins to change shape
and transport substances
against gradient
- Muscles
- Provides energy for muscles to contract
- Phosphorylation
- 1) ATP is synthesised from ADP and
inorganic phosphate, using energy
from energy releasing reactions
- 2) The ADP is
phosphorylated to form
ATP and a phosphate bond
- 3) The energy is stored in this
bond. When this energy is
needed, the ATP breaks down to
ADP and an inorganic phosphate
