**Question:** Choose the correct coenzyme – transferring group pair.**Options:**- ○ lipoamide – aldehyde- ○ NADH – acyl- ○ coenzyme A – acyl- ○ tetrahydrofolate – electrons- ○ thiamine pyrophosphate – glucose **Note:**The text provides multiple-choice options to identify the correct coenzyme pair for transferring specific chemical groups. **Question:**What molecule has a phosphoryl-transfer potential lower than that of ATP?**Options:**- 1,3-BPG- Creatine-phosphate- Glucose-1-phosphate- PEP- UTP**Explanation:**The question asks which molecule has a lower ability to transfer a phosphate group compared to ATP. In cellular biochemistry, understanding phosphoryl-transfer potential is crucial because it determines how energy is transferred and utilized in biological processes.

Cofactors are non-protein parts of an enzyme which are necessary for an enzyme to function.Phosphate transfer potential (PTP) is simply a measure of of hydrolysis of a phosphate containing group. If the value is negative, it indicates that the hydrolysis reaction yields energy. The magnitude of the value indicates the amount of energy released, which is the phosphate transfer potential of that group.Lipoamide transfers acyl group, electrons and protons.NADH transfers hydride ion (1 hydride ion = 1 H+ + 2 e-).Coenzyme A transfers acyl groups.Tetrahydrofolate transfers 1 carbon groups like methyl, methylene, methenyl, formyl or formimino groupThiamine pyrophosphate is responsible for cleavage of bonds near carboxyl group of a molecule and then transfering the rest of the molecule.So, the correct option is Coenzyme A - acyl.Molecule of phosphate hydrolysis (kJ/mol)ATP (to ADP and Pi)-30.51,3-BPG-49.3Creatine phosphate-43Glucose 1-phosphate-21PEP-61.9UTP-30.5PTP of a molecule is the magnitude of the negative value of hydrolysis of the phosphate group. As you can see, only glucose 1-phosphate has the maginute of lower than ATP.So, the correct option is Glucose 1-phosphate.Coenzyme A - acylGlucose 1-phosphate
