anaerobic respiration and others

Postby jamie_1002 » Mon Apr 11, 2005 3:55 am

HI,

Could someone please help me by

1) outlining the biochemical pathways by which energy is released from glucose in
anaerobic respiration.

2) state what happens to the products of anaerobic repsiration when oxygen becomes
available.

3) How do ATP and ADP differ in free energy content.

Thanks in advance.

1) outlining the biochemical pathways by which energy is released from glucose in
anaerobic respiration.

This occurs in the cytoplasm... Glucose only goes through glyclosis and does not proceed onto the Krebs cycle which requires Oxygen. Only 2 ATP is formed and is released into the cytoplasm for use in the cell.

2) state what happens to the products of anaerobic respiration when oxygen becomes
available.

When Oxygen becomes available normal cellular respiration can occur (Krebs cycle + Electron transport) NAD+ is produced during anaerobic respiration and can be used during glyclosis and the Krebs cycle to pick up and transport Carbons from Glucose.

3) How do ATP and ADP differ in free energy content.

ATP - Contains the largest amount of chemical energy - Which is stored in the bonds that hold the phosphates (3) to each other

ADP - Contains less chemical energy - less bonds holding phosphates (2)

Hope that helps...
