- ENERGY & ATP
- SOURCE OF ENERGY
- "universal energy currency in living organisms"
- cellular metabolic processes
- synthesis of organic chemicals
- chemical reactions
- Advantages
- small energy released
- one enzyme for quick & easy energy releasage
- efficient
- controlled
- soluble
- STRUCTURE
- made on the stalked particles of mitochondria
- is a nucleotide
- organic base Adenine (A)
- phosphanydride bond
- 30.5 kJmol-1 of energy
- unstable & reactive
- immediate energy
- not good for long-term energy (fats & carbohydrates better)
- ROLES
- Metabolic Processes
- DNA & protein synthesis
- Active Transport
- ions against a conc. gradient
- Muscle Contraction
- Nerve Impulse Transmission
- Na & K pumps
- Secretition
- can be packages & transported by secretory products in vesicles
- Metabolic Processes
- IMPORTANCE OF ATP
- 30 kJmol-1 + ADP + Pi ? ATP
- ATP sythase
- reversible reaction
- ATP ? ADP + Pi + 30 kJmol-1
- ATPase hydrolyses
- exogonic = energy released
- lowers activation energy
- 30 kJmol-1 + ADP + Pi ? ATP
- SOURCE OF ENERGY
