, cells require energy for many processes :




LI
Metabolism-all reactions in body

Anabolism
= making big molecules from small ones


catabolism :
making big molecules into small ones

cell Division

Active Transport = need energy substances ,
more against concentration gradient

Movement-mechanical work , ex. Muscle contraction -




plant+ animal release energy from glucose respiration this energy used to make ATP

·
adenosine triphosphate (ATP) able to supply cells with an energy form they can use .




·
For
ATP used energy transfer in all cells in all living things + therefore known as universal

energy currency.
·
Mitochondria through aerobic respiration is responsible for ATP

structure of ATP

triphosphate (Pi(
·
50 sugar


·
known as phosphorylated nucleotide - similar structure to a DNA nucleotide .




HOW ATP releases energy

·
When energy needed by a cell ,
ATp broken down into ADP + P;

↳
hydrolysis reaction -

phosphate bond broken +
energy released

I reaction catalysed by ATP hydrolase
·
ATP hydrolysis can be coupled with other energy requiring reactions In cell . Means energy

released used directly to make coupled reaction happen rather than being lost as heat
.


·

Inorganic phosphate can already be put
released to use -


can be added to another compound-

PHOSPHORYLATION - makes compound more reactive .




ATP can be resynthesised in a condensation reaction between App + Pi happens during resp/

photosynthesis + catalysed by ATP synthase
