We need to explain the role of atp as an energy cobbler.
00:06
Take note to those important thing that i'm going to explain to you right now.
00:12
So atp is known as adenosine triphosphate.
00:24
This atp, it is the energy currency for all cellular process.
00:30
Atp gives energy for both indurgonic and exergonic reaction, which require a small input of energy for activation.
00:56
When breaking the chemical bonds within the atp energy is released and can be used for cellular work, the bond in atp is broken and reformed easily.
01:12
Atp also acts like a rechargeable.
01:22
So they are act like a rechargeable battery that powers cellular process from dna replication to synthesis of proteins.
01:34
Atp is hydrolyzed into adp in the following reaction.
01:41
Atp plus h2o yields to adp plus phosphate plus free energy.
01:55
Similarly, adp is combined with a phosphate to form atp, like in the given reaction, adp plus phosphate plus free energy is atp and water.
02:19
Now we are going to discuss about atp and energy coupling, atp and energy coupling.
02:34
So we have delta g.
02:36
The delta g calculated for the hydrolysis is one mole of atp, atp into adp and phosphate is negative 7 .3.
02:55
Kilo calories per mole or that is negative 30 .5 kilojoules per mole.
03:03
Even though this is true only under standard conditions and the delta g for one mole of atp hydrolysis in a living cell is approximately double the value at standard condition that is 14 kilo calories per mole or 90.
03:25
Negative 57 kilojoules per mole.
03:30
Atp is very unstable...
