ATP Flashcards
1
Q
Production of ATP
A
- Made from ADP + Pi
- Energy is stored in the phosphate bond
- ATPase catalyses the breakdown of ATP
- ATP synthase catalyses the production of ATP
2
Q
What is energy needed for?
A
Metabolism Movement Active transport Maintenance, repair and division of cells Production of substances Maintenance of body temp.
3
Q
The flow of energy through living organisms
A
- Light energy form the sun is converted by plants into chemical energy during photosynthesis.
- The chemical energy in the form of organic molecules, is converted into ATP during respiration.
- ATP is used by cells to perform useful work.
4
Q
How ATP stores energy
A
Adenosine triphosphate (ATP) has three phosphate groups. The bonds between these phosphate groups are unstable and so have a low activation energy, which means they are easily broken. When they do break they release a considerable amount of energy. ATP + H20 > ADP + Pi + E
5
Q
Synthesis of ATP
A
App is synthesised using energy released during the transfer of electrons along a chain of electron carrier molecules in the chloroplasts or the mitochondria.
