Exergonic reaction
an endergonic reaction
Dehydration Synthesis
It is a hydrolysis reaction.
- Glucose - Which is broken down into 2 Pyruvate -ADP+Pi and NADPH+
endergonic
Step 1: Glucose + ATP --(Hexokinase)--> Glucose 6 Phosphate + ADP Step 2: Glucose 6 Phosphate --(Phosphoglucose Isomerase)--> Fructose 6 Phosphate Step 3: Fructose 6 Phosphate + ATP --(Phosphofructose Kinase)--> Fructose-1,6-bisphosphate + ADP Step 4: Fructose-1,6-Bisphosphate --(Aldolase)--> 2Glyeraldehyde 3 Phosphate Step 5: 2Glyceraldehyde 3 Phosphate + 2(PO4)3- + 2NAD --(Dehydrogenase)--> x2 1,3-Bisphosphoglycerate + 2NADH Step 6: x2 1,3-Bisphosphoglycerate + 2ADP --(Phosphoglycerate Kinase)--> x2 3-Phosphoglycerate + 2ATP Step 7: x2 3-Phosphoglycerate --(Phosphoglycerate Mutase)--> x2 2-Phosphoglycerate Step 8: x2 2-Phosphoglycerate --(Enolase)--> x2 Phosphoenolpyruvate Step 9: x2 Phosphoenolpyruvate + 2ADP --(Pyruvate Kinase)--> 2Pyruvate + 2ATP * I realsise most of these rections could be divided through by 2 but you've got to realise that for 1 glucose in glycolysis there is a net gain of 2 ATP's, 2 NAD's are reduced and 2 molecules of pyruvate are formed
Exothermic - big time.
Via the enzyme 'pyruvate kinase' , phosphoenolpyruvate is combined with Adp and Pi to {100%} YIELD pyruvate [pyruvic acid] and Atp. Starting from Glucose, there are at least six separate [because each step "has" its own Enzyme to THOROUGHLY control the yield of the reaction] steps that precede the above.
It is a hydrolysis reaction.
- Glucose - Which is broken down into 2 Pyruvate -ADP+Pi and NADPH+
break down of ATP into adp occurs when the one peptide bond of ATP is broken down.
It is the light reaction. Then they moves to dark reaction
Net inputs: glucose, ADP, NAD+ Net outputs: Pyruvate, NADH, ATP
Glycolysis. It breaks down glucose to pyruvate and makes a net gain of 2 ATP, 2 H+, and 2 NADH. Here is the general equation for glycolysis. C6H12O6 + 2[NAD]+ + 2[ATP] + 2[P]i = 2 Pyruvate + 2[NADH] + 2[ATP]
Usually energy in the body's obtained from converting ATP into ADP. However, glycolysis, the process of converting glucose to pyruvate, releases energy that turns ADP into ATP.
The hydrolysis of ATP to ADP is used to drive a reaction in metabolism.
