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
