When making bread with common yeast, the reaction starts as an aerobic process and then becomes an anaerobic process after the oxygen is spent. A baker has created a new strain of yeast which contains no cytochrome c gene and, thus, no cytochrome c protein. This will affect what the yeast strain can do to obtain energy.
Use the passage to answer the question.
What will this yeast strain do more of, compared to a normal strain?
