<u>Explanation</u>: <em>Glycolysis</em> is the metabolic process through which <em>glucose molecules</em> are broken down, whereas <em>β-oxidation</em> is the catabolic process through which <em>fatty acid molecules</em> are broken down.
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.
