I have to choose a project for microboilogy. Naturally I'm choosing to study lactic acid fermintation.

I'm here for help! I've browsed online and found some usefull stuff, however I thought it would be better to go straight to the source.

Anything is appreciated, thanks!

What do you want to know about it that isn't readily available online?

Is this a troll? What is lactic acid "fermintation"? How is a blood pump related to micro?

Typically Clostridrium just shoots out of my fingernails because I pull so hard. It's actually pretty cool.

Give MicrobeWiki a peek, but that's more focused on species than process.

I don't know the first thing about the "science of pump." All I have to offer is the very serious advice to do a better proofreading job on your final paper than the job you did on your post here.

Also, has anyone petitioned APA yet to get a dedicated citation type specifically for mountainproject?

Haters!

Gimme a break, I'm typin all this on my damn cell phone. Hence the bad grammer and punctuation. Thanks for the unnecessary insults! I'm no troll.

Your arms perform anaerobic respiration, aka fermintation. In the absence of 02 they create lactic acid, that's what gets you pumped!

Thanks buff, ill check out microwiki.

climBing hard and over griPPing getz me pumped. Not no fermintations.

Thanks will, ill check that out.

I really don't want to argue with people on here, so I'm not.

Fermentations get me krunk!

So lactic acid production and fermentation are both mechanisms that avoid the TCA cycle and the electron transport chain. However, they are not the same thing. We produce lactic acid... we do not ferment anything. Fermentation is the production of ethanol from pyruvate. Yeast ferments... hence alcohol. The reason you build up lactic acid is because muscles don't have oxygen. When they do not have oxygen, the electron transport chain is inhibited, thus backing up respiration. Pyruvate is not imported into the mitochondria and the it is processed into lactic acid. This provides gets rid of pyruvate but doesn't produce much energy, where as the TCA cycle and respiratory chain produces like ~28 ATP molecules. Lot out there in weight lifting field about this stuff.

More importantly, you spelled grammar with an "er" when you were tell us you where sending messages from your phone.

carebear is correct, lactic acid fermentation is a possible end stage of the glycolitic pathway but is a separate mechanism.
I still have no idea what the OP was hoping to get from MP feedback though.
IMO taking a look at few of the theoretical possibilities of muscular fatigue would be more interesting or perhaps more of a holistic picture of what happens when you "pump out". Unless you're only interested in the actual mechanism behind the sensation of being pumped.

Perhaps it would be of interest to OP as to why lactic acid needs to be formed (or ethanol in fermentation). Pyruvate itself doesn't pose any threat to the cell, but the cell possesses a limited about of NAD+. During glycolysis NAD+ is reduced to NADH. In order for glycolysis to continue in anaerobic conditions, pyruvate must be reduced to lactic acid in order to get NAD+ back.

I would think studying malolactic fermentation would be a much better topic.

Wait...so when I get pumped it means my muscles are fermenting? No wonder I always fall off and feel strange...

...and want a beer.

No, really, you should study Lance Armstrong. He's retired and probably not doing anything right now. Apparently his body is an anomaly and doesn't product lactic acid and that's how he kept winning the Tour with a VO2/max of 82 without using EPO. I've had "The Science of Lance Armstrong" on hold on my Netflix cue for a decade. I'm sure it will come out soon.

Yeah, I'm sure it had nothing to do with the drugs.

Have you checked out the news lately? Apparently Lance was the king of the dopers. Google that shit. You don't have to believe all the lies he fed everyone for all these years.
