PHOTORESPIRATION Flashcards
1
Q
Photorespiration
A
recycling pathway
2-PG, ATP, NADPH, glutamate
products: 3-PGA, CO2 and NH3
chloroplast, peroxisome, and mitochondrion
2
Q
Peroxisome
A
3
Q
Photo-respiratory cycle
A
Dephosphorylation and phosphorylation (ATP) in chloroplast
oxidation, reduction, transamination in peroxisome
condensation in mitochondrion (generate CO2 and NH3)
glycine (peroxisome) –> serine (mitochondrion) –> glycerate
product: 3-PGA
4
Q
Transamination
A
GGAT
SGAT
important regulators of amino acid content in plants
5
Q
Glycine decarboxylase complex
A
GDC
mitochondria
carbon carrier: THF
SHMT
