EVOLUTION CONNECTION AIP synthases are found in the prokaryotic plasma membrane and in mitochondria and chloroplasts. (a) Propose a hypothesis to account for an evolutionary relationship of these eukaryotic organelles and prokaryotes. (b) Explain how the amino acid sequences of the ATP synthases from the different sources could he used to support or refute your hypothesis.

Biochemists working with isolated mitochondria recognize five
energy "states" of mitochondria, depending on the presence or
absence of essential substrates for respiration-O, ADP, oxidizable
substrates, and so forth. The characteristics of each state are:
state 1: mitochondria alone (in buffer containing P;)
state 2: mitochondria + substrate, but respiration low due to
lack of ADP
complex 4 cytochrome C
oxidase
COxidation of one molecule of NADH by the ETC result in transport of 10 protons across the membrane.
The c-ring of the ATP synthase in your experimental system contains 12 c subunits. Based on the
"binding-change" mechanism of ATP synthesis, how many ATP molecules would be produced from one
NADH molecule?

' ink about this in terms of howETPUM can generate a net gain in ATP by processing polyurethane. Remember that the degradationof polyurethane by polyurethanase does not expend ATP. In order to answer this question, address eachof the following questions in your answer:a. Is there a net gain or loss of ATP during the transport of the citrate?b. Consider the ATPs that can be generated via substrate-level phosphorylation. Will glycolysis beuseful for generating any ATPs during growth on polyurethane? How many ATPs can be generatedvia TCA? Is this enough to support growth (is there a net positive in the ATP tally)?c. Now consider how else ETPUM can generate ATPs (if not by substrate- level phosphorylation). Canthis process generate a net positive in the ATP tally?d. Now explain the importance of oxygen as relates to the ATP tally.arrow_forward

Thanks A 45 year old man was rushed to the ER after ingesting "Galaxodin," a hypothetical poison. Explain why Galaxodin is toxic knowing that it increases the pH of the intermembrane space of mitochondria! You will need to give a comprehensive explanation of the process of energy conversion starting from NAH ending in ATP under normal conditions. Include details such as the transfer of electrons, the proton gradient, and chemiosmosis, NADH and FADH2, and ATP synthase must be mentioned. The majority of your grade will come from this part.

At the end of one spin of ATP synthase when the proton is in a position to leave to the intermembrane space the Asp comes into close contact with another very highly conserved residue Arg 210.
