(b)
Interpretation:
Whether the vitamin B6 is involved in (1) β-oxidation pathway, (2) ketogenesis, (3) lipogenesis, or (4) conversion of ketone bodies to acetyl CoA, has to be determined.
Concept introduction:
Vitamins are defined as the micronutrients that are needed in a small amount for the proper functioning of the metabolic activities in the organisms. Cofactors are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Cofactors cannot perform on their own alone. Vitamin B6 helps in the treatment of low levels of pyridoxine. Our body cannot produce it naturally hence it must be obtained from supplements.
(c)
Interpretation:
Whether pantothenic acid is involved in (1) β-oxidation pathway, (2) ketogenesis, (3) lipogenesis, or (4) conversion of ketone bodies to acetyl CoA, has to be determined.

It contains cobalt. It plays a major role in the production of red blood cells and DNA synthesis
(d)
Interpretation:
Whether riboflavin is involved in (1) β-oxidation pathway, (2) ketogenesis, (3) lipogenesis, or (4) conversion of ketone bodies to acetyl CoA, has to be determined.

Cofactors are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Cofactors cannot perform on their own alone. Riboflavin is also known as vitamin B2. It is a water-soluble vitamin, so it dissolves in water. All vitamins are either water soluble or fat soluble. Water-soluble vitamins are carried through the bloodstream, and whatever is not needed passes out of the body in urine. Hence it must be consumed in excess.

OH O .lari. -CH₂- NAD+ Select Draw Rings More / ||| ||| C 0 H 44 H 4 Erase +NADH- ho given molecule to show the product of the oxidation reaction using FAD as the oxidizing agent. Include thearrow_forwardWhich statement is TRUE regarding ketone bodies? O Ketone bodies are only formed during times of starvation. Excess acetoacetate produced during ketone body production is mostly exhaled. O Ketone bodies can easily travel from one tissue to another in the body due to the preser Coenzyme A. O Ketone bodies tend to be formed when oxaloacetate concentrations are high. O Ketone bodies can be used as a source of acetyl-CoA in target tissues when blood glucosarrow_forwardConsider this chemical reaction. What chemical is the oxidizing agent?

- Acetyl COA (ACC) is a critically important molecule in metabolic pathways. This molecule can be used for gluconeogenesis or fatty acid synthesis. It can also proceed through the TCA cycle to generate energy. ACC is also hormonally regulated. Hormones induce a phosphorylation cascade which can activate or deactivate ACC. Which of these hormones would activate ACC? A) glucagon B) insulin C) epinephrine D) glucose E) testosteronearrow_forwardConsider the docosanoic acid, C21H43CO2H Label the alpha and beta Carbons. Draw each acyl CoA derived from this fatty acid. How many acetyl Co A molecules are formed by complete beta-oxidation? How many cycles of beta-oxidation are needed for complete oxidation? How many molecules of ATP are formed from the complete catabolism of this fatty acid? Show the complete computation. How many moles of ATP per gram of fatty acid is formed from the complete catabolism of the given fatty acid?
