Textbook Question
Chapter 3, Problem 3AWK
Mitochondria resemble a bacterial cell in a number of ways. Some scientists hypothesize that mitochondria evolved from aerobic prokaryotes that were engulfed by anaerobic eukaryotes, and now both have evolved together in a mutually advantageous way. Can you think of an explanation for why it might have been advantageous for both cells to enter into such an arrangement?

If mitochondria originated as proteobacteria and chloroplasts are descended from cyanobacteria, where does the rest of the eukaryotic cell come from?
How can the hypothesis that asserts that chloroplasts as well as mitochondria were primitive prokaryotes that associated in mutualism with primitive anaerobic eukaryotic cells be corroborated?

- Which statement regarding mitochondria is true? Group of answer choices Mitochondria are semi-autonomous which means they can move, make proteins, and divide.

- 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. 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 loafarrow_forwardTrue or false Some prokaryotes can live in oxygen-free environments such as water logged soil, in ponds where water does not flow, and in the intestines of animals that transfer glucose to NADPH and then pass the electrons down the electron transport chain that is joined to ATP synthesis by chemiosmosis.arrow_forwardImagine that you develop a procedure to measure the pH of in the matrix and the intermembrane space of a mitochondrion.

The pH within the matrix will contain more H+ and have a lower pH compared to the intermembrane space. The pH within the matrix will contain more H+ and have a higher pH compared to the intermembrane space.arrow_forward
