Concept explainers
(a)
Interpretation:
Whether the statement “both processes occur in the cell cytosol” contrasting the processes of lipogenesis and the β-oxidation pathway is true or false has to be identified.
Concept introduction:
The β-oxidation pathway is defined as a repetitive series of four biochemical reactions in which acyl CoA is degraded to acetyl CoA by the removal of two carbon atoms at a time. NADH and FADH2 are also produced in this pathway.
Lipogenesis is the process employed for the synthesis of fatty acid. The starting precursor for the synthesis is acetyl CoA. The enzyme employed for the process is fatty acid synthase. It is a multienzyme complex that ties the reaction responsible for the synthesis of fatty acid.
A cyclic process for the chain elongation occurs in the enzyme fatty acid synthase. The one turn of this cyclic process constitutes four reactions. The various intermediates formed in the process are associated with a carrier protein known as ACP.
(b)
Interpretation:
Whether the statement “both processes use the same enzymes” contrasting the processes of lipogenesis and the β-oxidation pathway is true or false has to be identified.
