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. Making bread is an aerobic process for the yeast. Since the air bubbles in bread are generated by yeast, how will the spaces in this bread compare to those in a loaf made using normal yeast?

A. more bubbles
B. differently-shaped bubbles
C. smaller bubbles
D. bubbles more on the interior of the loaf

PART 2: What will this yeast strain do more of, compared to a normal strain?

A. electron transport
B. carbon dioxide production
C. fermentation
D. ATP synthesis
