Answer:
Pyruvate kinase
Explanation:
Yeasts convert glycerol and sugars into glyceraldehyde 3-phosphate (G3P) through independent pathways. Then, G3P forms pyruvate and, in some circumstances, pyruvate is converted in ethanol, which can be used as energy sources. If the mutation affects any reaction before G3P formation, it will only affect yeast growing either on sugar or pyruvate but not both.
Pyruvate kinase is the only enzyme on the list acting after G3P is formed and before pyruvate is formed. All other options are enzymes acting only in the formation of G3P from sugars. Meaning that only pyruvate kinase mutants will lack the ability to grow on both sugars and glycerol.

The glycolysis of glucose occurs in the cellular component
of the cytosol. The cytosol is found in the organelles in the body in which
these substance or particles are usually suspended, in which is a vital part of
where glycolysis of glucose occurs.
The four types of macromolecules in cells are nucleic acids, lipids, proteins, and carbohydrates.
