Atp Flashcards
What kind of molecule is atp?
= an nucleotide deprivative
= adenosine triphosphate
= immediate source of energy for metabolusm and biological processes
What is linked to the releasure of energy in atP?
= the 3 phosphate heads
What is the structure of ATP?
components:
= adenine- nitrogen base
= ribose- pentose sugar
= 3 phosphate heads
Where is atp made?
= during respiration from ADP
= condensation reaction- addition of an inorganic phosphate head
= enzyme- ATP synthase
=- takes small amount of energu
How does ATP release energy?
= hydrolysed
= into ADP + PI
= by breaking one of the bonds between the inorganic phosphate group
= releases a small amount of energy to the surroundings used for chemical reactions
=USES ATP hydrolase
How is atp an immediate source?
= only one bond has to be hydrolysed to release energu
What is phosphorylation?
=transfer energy when the bond of an inroganic phosphate is hydrolysed it is released
= if the inorhanic phosphate that is broken off is bonded to a different compound- that compound will gain the energy and becomes more reactive
= *first stage of respiration
What is the difference between ATP providing energy and glucose?
= ATP is immediate source of energy
What is the first reason ATP is a managable source?
1: releases energy in small manageable amounts so no energy is wasted
= cells do not overheat from wasted energy
= less likley to run out of reasources
COMPARISON:
=glucose releases large amounts of energy that could result to wasted energy
What is the second reason ATP is a managable source?
= small and soluable molecule
= easily transported around a cell
= common with glucose can move around cytoplasm
What is the third reason ATP is a managable source?
= only one bond is broken/hydrolysed to release energy- immediate
COMPOUND:
= glucose would need several bonds- so takes much longer
What is the fourth reason ATP is a managable source?
= phospholyration
=ATP can donate an inroganic phosphaye bonded to another molecule and make it more reavtibe
=cannot be done with glucpse
What is the fith reason ATP is a managable source?
= ATP cannot pass out of the cell - the cell always has an immediate source of energy
= glucosde can
= no protein carriers atp can attach to
