Have a huge (college level) biology take home test!

I have a very important biology take home test at my college. I have a few questions that i would like help with. It is due tuesday. I am wondering if anyone on this website is good at biology and is willing to help me. I am ok at it but not great. Please private message me here.

these are two of the questions I dont understand. I am hoping someone can answer these and explain to me why afterwards maybe on the phone or through email. (i know the questions have alot of parts but i answered 8 others like these -_-)

3. For Cellular respiration to function we must breathe in oxygen and breathe out carbon dioxide
a-Carbon Dioxide is the product of the oxidation of what molecule (what molecule begins the process of cellular respiration)?
b.where along the pathways is carbon dioxide released? (be specific)
c. For which pathway is the oxygen we breathe required?
d. If oxygen is in short supply what alternative pathway is used (in us)
e. how many ATP's are made in total from this alternative pathway
f. What are the end products of this pathway? (in us)



4. Compare and contrast in chloroplasts (photosynthesis) and in mitochondria (cellular respiration) the two components: Chemiosmosis and the electron transport chain.(In your answers make sure to point out the similarities and the differences)

a.describe the function of each component (i.e. what is the function of chemiosmosis and the electron transport chain in chloroplasts and in mitochondria How are they similar? how are they different?)
b.What drives each of these components for each system? (starting materials? ending materials

 

a- Glucose
b- Mitochondria
c- never understood
d- Anaerobic Respiration
e- never understood
f- Lactic Acid

Did you want the answers or explanation?

Hope this helps.

 

ansers preferebly but i dont know if anyone on this site is good at bio

 

I studied AS Biology, got an A.

 

3. For Cellular respiration to function we must breathe in oxygen and breathe out carbon dioxide
a-Glucose begins the process of cellular respiration (Glycolosis)
b.It is released during the Kreb's cycle, the 6 carbon citric acid (formed by acetyl coA & oxoloacetate) loses carbons gradually throughout the cycle (eventually ending up where it started as Acetyl CoA).
c. Krebs Cycle, and Electron Transport chain as Oxygen is the last electron acceptor in the 'relay' of electrons from carrier molecule to carrier molecule (decreasing in energy levels).
d. Either Glycolosis (as it's anaerobic) or Fermentation, as in Lactic acid fermentation in muscles during exercise.


Will have to do a bit of reading to help ya with the last of it. Hope this was useful to you.

 

Lol considering it was close to a month ago, he probably had to turn it in, but what a nice person for helping

 

Didn't notice but at least the information is now available on here.
