Question

write the reaction of the Krebs cycle that result in the formation of a phosphoanhydride bond by substrate level phosphorylation.

Answer 1

Phosphoanhydride bond is the bond between the phosphate molecules,which are energy rich and contains -30.5kj/mol energy

and substrate level phosphorylation is a metabolic processs that results into production of atp and adp by conversion of high energy substrates(with or withoutphosphate groups)using lower energy product and release in some chemical energy.

here, as asked about kreb cycle, here is the complete equation for the same,

acetyl-coA + 3NAD+ +FAD + GAD(or ADP) +3H2O ------------------> 2CO2 + 3NADH + FADH2 + GTP(or ATP) +H2O

here, the energy is stored in the NADH and GTP or ATP molecules in the form of bonds.

below is the complete kreb cycle figure,have a look on the various steps.

here the complete discription is given of the kreb cycle.

the process begins with the acetyl coa reacting with citrate and continuous.

the energy released in the kreb cycle is used in the reduction of three NAD+ and one FAD and the production of one ATP or GTP.

This is the basics of kreb cycle along with the complete reaction of kreb cycle .
