You saw a video in which a researcher conducted a series of experiments to understand how a mutation affecting yeast mitochondria functioned. In the first experiment, he was seeking to determine whether the mutation (present in the -MPC yeast) 1) prevented pyruvate from getting inside the mitochondrion -or- 2) prevented the mitochondrion from breaking down pyruvate into Acetyl CoA properly. To test his hypothesis that the mutation had an effect on pyruvate’s ability to get inside the mitochondrion, he exposed normal yeast and mutant yeast to pyruvate for a period of them, before isolating and lysing the mitochondria of each set, and testing their mitochondrial extracts for levels of these products. If he had gotten the following result indicated in this image, what would this indicate?

In what order does a Listeria infection occur? 1. Listeria bacterium produces ActA and harnesses host cell’s resources to create a microfilament “rocket” 2. Listeria bacterium binds to a receptor on the host cell surface 3. Listeria bacterium is ingested by the host organism 4. Listeria bacterium releases a protein that breaks apart the phagosome, allowing the bacterium to evade destruction 5. Listeria bacterium is not detected by the host cell as as a pathogen because it is surrounded by a membrane entirely made of up the host’s proteins and phospholipids 6. Listeria bacterium reproduces via binary fission
