Question

For Q. 1 i know that i have to use the equation E= A(reduced)-A(oxidised), i am given the one thats being reduced(NAD+) but im not given the info for one being oxidised.

Q.2 i think that electrons are being transferred from NAD+ to isocitrate

Q. 3 im not sure about this one.

You are studying the following Krebs Cycle reaction Isocitrate NAD o-kstoglutarate+ CO NADH You have the following information: This oxidation/reduction reaction involves the transfer of 2 electrons. The AG for this reaction 2772 cal/mole F 23,100 cal/volt-mole For the ATP synthesis reaction: ADP P ATP AG +7500 cal/mole EO 0.32 volts NAD H 2e NADH 1. The value of AE for the Krebs Cycle reaction is a. +0.06 volts b. 0.06 volts c. +0.12 volts d. 0.12 volts e. There is insufficient information to determine the answer to this question 2. In this reaction electrons are transferred from a. Isocitrate to NAD b. NAD to isocitate c. Isocitrate to a NAD to NADH e. There is insufficient information to determine the answer to this question B. In a functioning cell under aerobic conditions Cie. In which electron transport oxidative phosphorylation is occurring, how many ATPs will ultimately be made as a result of this reaction? a. b. 1 e. There is insufficient information to determine the answer to this question

Explanation / Answer

1. Yes, you are right. Insufficient information to answer this question.

Option: e

2. Electrons are transferred from Isocitrate to NAD+

Option: a

3. In each krebs cycle, the given reaction takes place once. In one Krebs cycle - one ATP will be generated.

Option: b
