You are studying a bacterial metabolic pathway that results in the synthesis of a product, vitalin, that is essential for survival. In the figure below, each number represents an intermediate product, and each letter represents the enzyme (protein) that catalyzes that step. 3 d>5°> Vitalin Compound - "> 1 – > Z. a 4 > Vitalin You find that bacteria with mutations in either c orf can survive, but a bacterial cell that has mutations in both c and f cannot survive. For every mutation, assume that the bacteria have other functional proteins in the pathway. Which of the following mutants can grow on media containing only intermediate 3? Select all that apply Mutant f Mutant b Mutant d Mutant c

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
