O.K., here's yesterday's question---it popped back into my head today.  What's the Krebs cycle?
494252
The citric acid cycle is also called the tricarboxylic acid (TCA) cycle and the Krebs cycle. It is the final common catabolic pathway for the oxidation of fuel molecules. Two carbons enter the citric acid cycle as acetyl CoA and two carbons leave as CO2. In the course of the cycle, four oxidation-reduction reactions take place to yield reduction potential in the form of three molecules of NADH and one molecule of FADH2. A high energy phosphate bond (GTP) is also formed.

The "light reactions" are Cellular Respiration, which is also called the Krebs Cycle.\n\nI know that there are "dark reactions", but I'm not sure what they are.\n\nHmm.. apparently they are known as the Calvin Cycle (see link)

Sir Hans Krebs discovered teh Kreb's cycle in cellular respiration. He used X-Rays of cells to see how cell respiration takes place

oxidation, i think.\n\nin this case, simple sugar reacting with oxygen in the air.\n\nIt's been a long time since my Chemistry 101 days.  Hope I got it right.

LOL, that is exactly what you saw. Welcome to today's fun and games on YA. Don't even try to figure it out, you will end up like myself with a very bad headache!!

you are correct in what you have said.\nevery cycle of respiration starts with a molecule of glucose which after several steps converts into pyruvate.(2 molecules)\nif then ,O2 is present, krebs cycle will occur, otherwise, fermentation takes place. end product of fermentation is a molecule of CO2 and either ethanol(plants) or lactic acid(animals). krebs cycle produces energy molecules (NADH AND FADH2 + ATP) NADH and FADH2 undergo electron transport system to yield 11 molecules of each pyruvate. thus, a total of 24(22 +1+1) ATP's are formed in kreb's cycle.CO2 is also released.\n4NAD+ +FAD +2H2O +ADP +Pi +pyruvate = ATP +3CO2 +4NADH+FADH2+4H+  = 3CO2 +24 ATP (IN KREB'S CYCLE)\nat the end of whole process of respiration, however, 36 ATP's are gained net (including ATP gain in other processes as well)

Oh Biology, how do I miss thee!!!!!  Ah that was some good times.  Cytochrome c oxidase is part of the respiration cycle and it accepts electrons.  That about all I can remember but thanks for the points and a trip down memory lane.

Uh, in the third tri-mester?  I'm having a hard time figuring out when pri - mortal begins?  Conception?  Third trimester?  Birth?  Geez, this is a toughie.  Why, I'll wager there are lots of folks debating this topic all over the world.

For your information Julie, I had already did my homework, I was wondering if anybody else knew what Methanothermus fervidus was. And my GPA is a 4.0 so you don't have to tell me that by reading more I will accomplish more. So now you let us know when you have a more complicated question about something other than a Ham & Cheese webstite. Thank you for your time in answering my question.

Adenosine TriPhospahte (ATP) and NADH2\n\nIn response to answer above: GTP is only created from tyrosine-kinase reactors and is not part of the krebs cycle

Say what? Congratulations for asking the most confusing question of the day! I've read it three times and I still haven't got a clue. Congratulations also to the gentleman above who did understand and gave you that exhaustive response. I hope you understood it and it answered your question (whatever the hell that was!)

The Krebs Cycles is hard!!!  I'll admit it.  I made up a song, and then I went dancing around the room singing it.  I got an A on the test.  I don't remember the Krebs Cycle now or the song but I think it went something like "Once there was a gang of six but they began to fight you see.  ATP (Is that right?) split them up and now they are two gangs of 3.  Da-dum."  I don't know.  You'll have to have a lot of imagination for that one but it works.

Kreb cycle and glycolysis - is what I initially answered\n\nHowever, if it is a standard test/textbook question the questioner is asking, then the answer is probably going to be 2 different mechanisms/pathways. It probably is going to be AEROBIC and ANAEROBIC metabolism.

Look at your diagram of Kreb's Carboxylic Acid Cycle.\nPick out oxaloacetic acid.\nWhat does it do?\nWhere does it come from? Remember the process is a cycle.

Krebs' cycle is also called Citric acid cycle or Tricarboxyllic cycle (TCA cycle).It takes place in the matrix of mitochondria.It is a phase of aerobic respiration during which pyruvic acid is completely oxidised into CO2 and H2O.All the enzymes necessary for the breakdown of pyruvic acid are present in mitichondria.Hannes Alfen Krebs, a British Biochemist explained this cycle of reactions in 1937-this cycle was named after him and he was given the Nobel Prize in 1957.The working involves too many steps to put down here. Please check this link for further information on the topic.\nhttp://chemistry.gsu.edu/glactone/PDB/Proteins/Krebs/Krebs.html

That's funny!  Thanks for the laugh. I'm trying really hard to think of something myself. Ah man, my mind just went blank!  I hate that.  I'll find something funny and share!  Thanks.
