Question
Chapter 15, Problem 6WIO
Summary Introduction
To explain:
Whether antibiotic streptomycin or diphtheria toxin would kill mitochondria and chloroplasts.
Concept introduction:
Mitochondria and chloroplasts are the organelles found in the eukaryotic cells. The bacterial cells lack these organelles. The main function of mitochondria is to perform aerobic respiration and generate ATP (adenosine triphosphate). On the other hand, the chloroplast helps in photosynthesis (in plants).

Below are three statements - two of which are truths and one is a lie. Which of the following statements is a lie?
Select one:
a.
Although both prokaryotes and eukaryotes have a plasma membrane that protects them from their surrounding, many of the extremophiles are prokaryotic and only a few are eukaryotic.
b.
Despite different in appearance, nerve and muscles cell have the same genetic material and the same ability to produce electrochemical impulses.
c.
Although very few in numbers, there are special prokaryotes that have a membrane-bound nucleus.
Which statement regarding mitochondria is true?
Group of answer choices
Mitochondria are semi-autonomous which means they can move, make proteins, and divide.
Mitochondria are used to recharge ADP into ATP.
Scientists theorize that mitochondria were once free-living alpha proteobacteria because mitochondria possess two membranes, bacterial genes, and a bacteria-like chromosome.

Apicomplexans evolved from a photosynthetic ancestor and have the remnant of a chloroplast. This organelle no longer acts in photosynthesis, but remains essential to the protist. Why might targeting this organelle yield an antimalarial drug with minimal side effects in humans?

Give typing answer with explanation and conclusionarrow_forwardPenicillin inhibits bacterial growth by preventing the cross-linking during peptidoglycan synthesis. Why does penicillin not inhibit growth of archaeal cells? Group of answer choices Most archaeal cells have a cell wall, but it is not composed of peptidoglycan. Archaeal cells do not have a cell wall. Penicillin is unable to penetrate the lipid outer membrane that blocks access of penicillin to the peptidogycan crosslinking enzymes. Pencillin is unable to penetrate the S layer to reach the peptidoglycan layer underneath.arrow_forwardWe will perform a gram stain on our samples, so be sure to bring your instructions on gram staining.
