Studying...
I really don't want to study, especially since I feel worse and worse for this exam. And I'm starting to feel worse and worse physically as well... I swear I get a little better and then I get even more sicker and right now I just kinda want to lay in bed.
I'm getting photosynthesis and respiration in Eukaryotic cells messed up... They do very similar things but they do different things as well. I'm pretty sure the energy to pump electrons into the intermembrane space comes from forming the oxidation of NADH and a little bit from FADH2.
All I really want to be doing right now is either in bed sleeping or on YouTube and watching 5566 MVs. It's really bad how I just want to procrastinate... :(
Will study, study, study!!!
I will get through the lectures right now in the next three hours hopefully and then I can just study recitation stuff and contrasting photosynthesis and all of cellular respiration in eukaryotes. I will get this down! Photosynthesis is a bit iffy though... I like Glycolysis -- that's easy! Two ATPs consumed, four made, 2 NADH, ending up with 2 pyruvates to go to pyruvate dehydrogenase.
Pyruvate is then transported to the mitocondria via a transporter and is reduced by the NAD and CoASH to form Acetyl CoA and CO2 is formed, along with another NADH (which comes from the citric acid cycle). Acetyl CoA is then oxidized to CO2 in the Kreb Cycle which ultimately produces 2 CO2, an FADH and 2 NADH. Also a GTP is generated, which is then converted to ATP. Shit, where is FAD regenerated? Is it in the electron transport chain like NAD? Yes! At complex 2! While NAD is at complex 1. And complex 1 is the NADH-CoQ Reductase. Complex 2 is teh Succinate-CoQ Reductase. And the other two are CoQH2Cyt C Reductase and Cyt C Oxidase, also known as Complex 3 and 4.
Okay. And then all the electrons pumped from the electron transport chain goes to the F0F1 ATPase (though really and ATP Synthase). That produces 28ish ATPs. Okay. That's not too bad.
