What are the naming conventions in regards to D and L and α and β for sugars
- If it is a 6 member-ed ring α will have the OH of the anomerica carbon above the plane of the figure and the β below the plane of the figure
- 5-member-ed rings are the opposite.
- α is below and β is above
- Further more the D form must be the mirror image of the L form and vice versa.
What signals lysosome degradatiin in glycoproteins

phosphorylated mannose
Insulin active what type of enzymes ?

phosphotases- remove or dephosphorylate
What are the three reversible reactions of the glycolysis and what do they do ?
- Step 1- hexokinase
- Phosphorylated glucose to G6P
- step 3- phosphofructokinase
- creates F16bisphosphate from fructose6P
- Step 10 - Pyruvate dehydrogenase
- converts PEP to Pyruvate
W Hat is the commuted step of Glycolysis ?
- Step 3
- PFK-1
Whats stimulate step 3 the committed step ?
- Insulin
- F26bisphospate
- F16) via positive feedback
- AMP
- all of which get rid of phosphate on the PFK-1
What is the significance of PFK-2
- found in the liver
- regulated by the pancretic enzymes
What events are happening/increase when insulin is high?
- glycolysis
- glycogenisis
- fatty acid synthesis
- PFK-1 and 2 is on
What is FBPhase?

enzyme that dephosphorylates F26Bisphospahates thus need to be off to increase glycolysis
What is the Pasteur effect

The slowing of glycolysis in o2
Gram positive bacteria
- pneumonia
- chlamydia
- Histoplasmosis
Gram negative bacteria
- Legionellea
- Ecoli
- typhoid fever
- Gonoccocus ( gonereah )
