How to remember Krebs Cycle?

Question

Is there an easy trick to remember steps in Krebs Cycle

Steps of Krebs Cycle:

• Citrate
• ISO-Citrate
• A-Ketogluatarate
• Succinyl-CoA
• Succinate
• Fumarate
• Malate
• Oxaloacetate

Answer 1

Here is an easy trick to remember Krebs cycle:

Can I Keep Selling Substances For Money Officer ?

• Can - Citrate
• I - ISO-Citrate
• Keep - A-Ketogluatarate
• Selling - Succinyl-CoA
• Substances - Succinate
• For - Fumarate
• Money - Malate
• Officer - Oxaloacetate

Answer 2

Here is an easy trick to remember Krebs cycle :

Organic Chemistry Is Only A Core Subject 'Cos Sience Fuels Life, Man

• Organic - Oxaloacetate
• Chemistry - Citrate
• Is - Iso-Citrate
• Only - Oxalosuccinate
• A Core - A-Ketoglutarate
• Subject ‘Cos - Succinyl CoA
• Science - Succinate
• Fuels - Fumarate
• Life, Man - L-Malate

Notes:

• H2O is produced at steps 1 and 8, so remember 18 for water.
• CO2 is produced at steps 4 and 5 which are COnsecutive
• NAD+ is reduced at steps 3, 5 and 9: all odd numbers
• FAD+ is reduced at step 7, and 7 looks like a backwards F. Also an odd number, so all reductions are on odd numbers.
• GTP is produced at step 6 and G looks like a 6
• All reductions are catalysed by dehydrogenase enzymes named after the corresponding intermediate.
• Just synthetases, synthases and the other ones to memorise now
