|
Many microorganisms cannot carry out photosynthesis and are
|
Heterotrophs
|
|
That Must synthesize
sugarsfrom reduced |
Organic molecules rather than from CO2
|
|
The synthesis of glucose from noncarbohydrate precursors is called
|
Gluconeogenesis
|
|
Although gluconeogenesis pathway is not identical with
|
Glycolytic pathway
|
|
They do share
|
7 enzymes
|
|
Three glycolytic steps are
|
Irreversible in the cell
|
|
1. Conversion of
|
Phosphoenolpyruvate to pyruvate
|
|
2. Formation of
|
Fructose 1,6 bisphosphate fromfructose 6-phosphate
|
|
3. Phosphorylation of
|
Glucose
|
|
These must be bypassed when pathway is operating
|
Biosynthetically
|
|
For example formation of fructose 1,6- bisphosphate by
|
Phosphofructokinase is reversed by enzyme fructose bisphosphate
|
|
Which is hydrolytically removes phosphate from
|
Bisphosphate
|
|
Usually at least 2 enzymes are involved in the conversion of
|
Pyruvate to phosphoenolpyruvate
|
|
The pathway synthesizes
|
Fructose as well as glucose
|
|
Once glucose and fructose have been formed
|
Other common sugars can be manufactured
