Localization of superoxide dismutase in glyoxysomes
from Citrullus vulgaris.
Typical organelles of a photosynthetic plant cell include the nucleus, vacuole, plastids, mitochondria, ribosomes, Golgi apparatus, lysosomes, glyoxysomes
, and peroxisomes.
Acquisition of membrane lipids by differentiating glyoxysomes
: role of lipid bodies.
However, the catabolism of these biomolecules occurs mainly in the peroxisomes of foliar tissues and in glyoxysomes during the plants' seed germination (Buchanan, Gruissem, Vickers, & Jones, 2015).
So that Equation (8) may be validated, the ATP amount, obtained from its application, was compared with the ATP amount calculated individually from the sum of acetyl-CoA, NAHD and FADH2 molecules number, and substrate level phosphorylation, generated in the oxidation of fatty acids with specific numbers of carbon atoms in glyoxysomes (Table 2).
Each break of carbon-carbon bond during [beta]-oxidation in glyoxysomes and peroxisomes produces one NADH which, in oxidative phosphorylation, produces 2.5 ATPs (step A-3 in Figure 1).
APX is found in the different cellular compartments such as stroma and thylakoid, microbody including glyoxysomes
and peroxisomes, cytosol and mitochondria.
Superoxide free radicals are produced in glyoxysomes

Others such as the primarily chloroplast-localized ASPX (EC 220.127.116.11), MDHAR (EC 18.104.22.168), glutathione reductase (EC 22.214.171.124) (Scandalios, 1993), and CAT (EC 126.96.36.199), principally located in the peroxisomes and glyoxysomes
(Prasad et al., 1994), can function in removing [H.sub.2][O.sub.2] (Foyer et al., 1994a).
