Study Set Content:
Sedoheptulose 7-phosphate through transaldolase and Glyceraldehyde 3-phosphate yield
fructose-6-phosphate and the aldose erythrose-4-phosphate
Transketolase catalyzes the transfer of phosphate two-carbon unit from
xylulose-5- phosphate
Transketolase catalyzes the transfer of phosphate two-carbon unit from xylulose-5- phosphate to
ribose-5-phosphate
Transketolase catalyzes the transfer of phosphate two-carbon unit from xylulose-5- phosphate to ribose-5-phosphate producing the seven-carbon
ketose sedoheptulose and the aldose glyceraldehyde
n a further reaction, catalyzed by transketolase, xylulose serves as the donor of
glycoaldehyde
In this case, (blank) is the acceptor
Erythrose 4- phosphate
In a further reaction, catalyzed by transketolase, xylulose serves as the donor of glycoaldehyde. In this case, erythrose is the acceptor, yielding the products
Glyceraldehyde 3-phosphate, Fructose 6- phosphate
The glycolysis and pentose phosphate pathways (PPP) ar
tightly connected
The glycolysis and pentose phosphate pathways (PPP) are tightly connected. The glucose entering the in cell membrane is rapidly phosphorylated by
hexokinase
The glycolysis and pentose phosphate pathways (PPP) are tightly connected. The glucose entering the in cell membrane is rapidly phosphorylated by HK and converted to
G-6-P
The G-6-P is metabolized either by the
glycolytic pathway, or by PPP
The G-6-P is metabolized either by the glycolytic pathway, generating
pyruvate and lactate
or by PPP to produce
NADPH
In glycolysis, oxidation utilizes
NAD and CO2
hile in PPP, oxidation utilizes
NADP
No ATP is generated in the
PPP
whereas it is a major product in
glycolysis
