2A. Red blood cells synthesize and degrade 2,3-bisphosphoglycerate (2,3-BPG) by a detour of the
glycolytic pathway, as shown below:
glyeeraldehyde 3-phosphate
GAP dehydrogenase
1,3-bisphosphoglycerate
bisphosphoglycerate mutase
ADP
phosphoglycerate kinase
2,3-bisphosphoglycerate
ATP
3-phosphoglycerate
2,3-bisphosphoglycerate phosphatase
phosphoglycerate mutase
2-phosphoglycerate
(i) The bisphosphoglycerate mutase/2,3-bisphosphoglcerate phosphatase reaction is catalyzed by a single enzyme,
BPGM. At alkaline pH, BPGM favors the mutase activity while at lower pH, BPGM favors the phosphatase
reaction. Use this information, along with the Bohr effect, to explain in the space below how red blood cells
respond to a metabolic defect where a patient experiences chronic, elevated levels of lactic acid. I
(ii) Individuals with red blood cell phosphoglycerate kinase deficiency suffer from moderate hemolytic anemia (a
condition where red blood cells self-destruct before their normal lifespan). They…
I'm confused about glycolysis and gluconeogenesis.
Question:
What is the function of glyceraldehyde 3-phosphate dehydrogenase?
Is it because of
-> The incorporation of a phosphate from ATP and reduction of glyceraldehyde 3-phosphate
or
->The incorporation of phosphate from inorganic phosphate and reduction of glyceraldehyde 3-phosphate.
or
-> The incorporation of phosphate from inorganic phosphate and oxidation of glyceraldehyde 3-phosphate
. Glucagon secretion causes inhibition of intracellular acetyl-CoA car-
boxylase activity by several mechanisms. Name all you
can think of.
