The correct answer i: A) It is a step in glycolysis
Beta oxidation is a catabolic process by which fatty acid molecules are broken down to generate acetyl-CoA. This process occurs in the mitochondria in eukaryotes and in the cytosol in prokaryotes.
Glycolysis is a metabolic pathway that converts glucose into pyruvate. Glucose is a simple sugar and beta oxidation is a process which includes fatty acids.
