Glycolysis, ETC, and Krebs cycle biochemistry product questions: (This is biochemistry)

1. If you created an artificial mitochondria and injected 1 molecule of pyruvate inside it, how many protons would accumulate in the intermembrane space of the mitochondria (starting from 1 molecule of pyruvate take it all the way to the end of the electron transport chain). 46 92 104 32

2. If you have created an artificial mitochondria and are injecting ONE molecule of Pyruvate inside it, how many molecules of ATP can be theoretically generated starting from 1 molecule of Pyruvate ( start from pyruvate and complete all the reactions to finish oxidative phosphorylation). Remember you also need to take into account any ATP generated via substrate Level phosphorylation. 11.5 12.5 32 30

3.) If you have generated an artificial mitochondria and have injected 1 molecule of Acetyl CoA inside it, how many protons can theoretically accumulate in the intermembrane space of the mitochondria at the end of electron transport chain? 46 32 46 36

4.) If you have generated an artificial mitochondria and have injected 1 molecule of Acetyl CoA inside it, how many ATP molecules can theoretically accumulate in the intermembrane space of the mitochondria at the end of electron transport chain and oxidative phosphorylation? ( Remember to take into accound ATP molecule generated via Substrate Level Phosphorylation) 12.5 9 10 32

5.) You have an artificial mitochondria, and you inject into it 10 molecules of a compound X that can donate a pair of electrons to complex III of the mitochondria, how many protons can theoretically accumulate in the intermembrane space of the mitochondria ? 60 100 104 112

Explanation / Answer

3) If you have generated an artificial mitochondria and have injected 1 molecule of Acetyl CoA inside it, how many protons can theoretically accumulate in the intermembrane space of the mitochondria at the end of electron transport chain? - 32 protons.

AcetylCoA gives 3 NADH+ and 1 FADH2

1 NADH gives 10 protons

10 x 3 = 30

1 FADH = 2 protons

so, 30+2 = 32 protons.

5)

Each electron crossing complex III release 4 protons into the intermemebrane space. Thus, 2 electrons will release 8 protons. 10 such molecules release 80 protons into the intermembrane space of the mitochondria.
