ATP

Postby bacu » Fri Jan 13, 2006 11:39 pm

when animals need to convert glucose into a usuable energy(ATP), what usuable process do they use?

The process is called cellular respiration, and consists of 3 stages:
1. glycolysis
2. Krebs cycle(sometimes reffered to as citric acid cycle)
3. Oxidative phosphorilation

there's also another...penthose-5-phosphate pathway

I tried but its quite complicated to understand the whole process, also many of the searc results I get back have outlined the whole process of Glycoolysis which my teacher hasnt taught us so it is quite confusing.

glicolysis is the first step to make ATP from Glucose. it is placed at cytoplasm. then for the next step it is placed at mitocondria, i mean the next step is Kerb cycle. :oops:

from a reference

Glycolysis, consisting of 8 steps. This pathway starts with glucose or
fructose and ends with pyruvate; part of the chemical energy of sugars
is converted into ATP and reduced-NAD.

Not only glucose, but also fructose i.e. in spermatozoa ;)

OMG, what happened to you? You are soo sensitive :? By quoting your sentence, it does not mean that you made a mistake then I made a correction for you. I just wanted to add information for you all here.

I really want to see when you are presenting a paper/journal in the front of the class and someone interrupts to ask you things. I want to see your face, I think it would like "Hey, someone's attacking me! I must defense myelf!" :P

Calm down, dude ;)


P.S. Btw, you did not say "only", but by reading your sentence everyone will think only glucose will make it. If you want to say "not only glucose", you should change "glucose" for "monosaccharide", or by adding "for example, glucose..."

I may sound like a language teacher, but well, can't deny that sentence is important when you start to write a report, especially scientific report. If you do not experience that, someday you will. Believe me because I learn much from my experiences ;)

This reminds me of the town olympiad i had last weak, where the questions were gramatically incorect :lol:
PS: maybe a good idea to change to hexose, cause ribose is a sugar too, and i don't think it can be used in cellular respiration
