Aerobically glucose can be broken down in 4 steps. List these steps.
|
1. Glycolysis
2. Oxidation of pyruvic acid 3. Krebs Cycle 4. Electron transport chain |
|
|
In Glycolysis :
One molecule of glucose is broken down to 2 molecules of what substance? |
Pyruvic acid
|
|
|
How many steps {reactions}in Glycolisis?
|
A sequence of 9 reactions.
|
|
|
In Glycolysis:
How many molecules of ATP are consumed for every molecule of glucose? |
2 ATP’s.
|
|
|
In Glycolysis:
How many molecules of ATP are synthesized by substrate phosphorylation per molecule of glucose? |
4 ATP’s.
|
|
|
In Glycolysis:
What is the net ATP production per glucose molecule? |
2 ATP’s.
|
|
|
In Glycolysis:
What are the 2 end products? |
The 2 ATP’s and the 2 NADH ‘s.
|
|
|
In Glycolysis:
In what of the cell does this process occur? |
In the cytoplasm.
|
|
|
With ANAEROBIC conditions what happens to the pyruvic acid resulting from glycolysis?
|
It’s reduced by the NADH formed in glycolysis to lactic acid.
|
|
|
With AEROBICconditions what happens to the pyruvic acid resulting glycolysis?
|
It moves into the mitochondria where it is oxidized; resulting in 2 CO2's being liberated, 2NADH’s being formed, and 2 acetyl coenzyme A’s being formed.
