okay, so right now im takin ap biology.

basically im confused as fuck about glycolysis, krebs cycle, electron transport chain, etc....

can someone describe it for me or give me a good link plez
thanks

maybe you should ask more specific questions and then we'll try to answer them

google ;<

i suck at those subjects

Yeah me too, I usually suck at biology.

me threeve. thats why i need help

hahaahah i failed that test,
but the krebs cycle is the dark reactions....or maybe thats calvin cycle...one of them

I'm in retard science class...

I hated maths, science, the only thing i did pretty kay was Physics my father still wonders how the hell did i pass that one without his help

The funny thing is, I was HORRIBLE at bio last year, but I'm amazing at chemistry this year. It doesn't make sense.

do you have the same teacher for both?

Krebs Cycle is another term for the citric acid cycle.

Basically:
the ACETYL-CoA transferrs its two-carbon acetyl group to an oxaloacetate group to form citrate.
The citrate then goes through a series of chemical transformations, losing two carboxyl groups as CO2.
The carbons lost as CO2 are from what was oxaloacetate, not directly from the ACETYL-CoA.
The carbons from the ACETYL-CoA then become part of the oxaloacetate
The loss of the ACETYL-CoA CO2 requires several turns of the citric acid cycle. Because of the role of the citric acid cycle in anabolism, they may not be lost since many TCA cycle intermediates are also used as precursors for the biosynthesis of other molecules.
Most of the energy made available by the oxidative steps of the cycle is transferred as energy-rich electrons to NAD+, forming NADH. For each ACETYL group that enters the citric acid cycle, three molecules of NADH are produced.
Electrons are also transferred to the electron acceptor Q, forming QH2.
At the end of each cycle the oxaloacetate has been regenerated, and the cycle continues.

.....thanks man
its....kinda clearer??

but i found this other website
admin lock please

Whoa, I learned this in my first year of college. I never touched this stuff when I was in high school. Glycolysis, yeah, but just the very basics.

I GOTS A POST IN BEFORE IT WAS LOCKED!

on topic: fuck that. Freshmen don't need to learn shit =p
