Question

The Citric acid cycle occurs in the mitochondria. There are nine biochemical reactions involved in the Citric acid cycle, and they are highly ordered. Select the correct order. (Note: These are abbreviated and do not show NAD, ADP, ATP, or FAD.)

Answer 1

. 2C- acetyl Co-A from the link reaction enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6- Citrate

The Citrate forms intermediate Isocitrate, which eventually formed 6-C alpha ketoglutarate.

The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed 5C-succinate.

5C -Succinate forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.

The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid from which other products are formed from.
