Basis of differentiation | Fatty acid synthesis | Beta oxidation |
Definition | Refers to a multi-step metabolic process in which fatty acids are produced from precursor molecule acetyl CoA and NADPH molecules through a series of anabolic reactions by enzymes | Is a multi-step metabolic process in which fatty acid molecules are broken down to produce energy through a series of catabolic reactions by enzymes |
Initiation of the process | Is initiates by acyl group carrier (ACP) | Is initiated by with coenzyme A (CoA) |
Occurrence | Occurs in the cytoplasm in both prokaryotes and eukaryotes | Occurs in the cytoplasm of prokaryotes and mitochondria in eukaryotes |
Type of reaction | Is an anabolic reaction | Is a catabolic process |
Enzymes involved | Is catalyzed by the enzyme fatty acid synthase, a multi-enzyme complex | Is catalyzed by different enzymes at different stages of the oxidation process |
Relationship with Energy | Energy is used by this process | Energy is released during this process |
Relationship with ATP | Uses ATP | Produces high-energy molecule ATP |
Reductants Used | Uses one reductant:
| Uses 2 reductants:
