Internal structure: Scientists think that on average, the Martian core is about 1,800 and 2,400 miles in diameter (3,000 and 4,000 km), its mantle is about 900 to 1,200 miles (5,400 to 7,200 km) wide and its crust is about 30 miles (50 km) thick.
Glutathione peroxidase (GPx) (EC 1.11.1.9) is the general name of an enzyme family with peroxidase activity whose main biological role is to protect the organism from oxidative damage.owever, glutathione peroxidase 4 knockout mice die during early embryonic development. Some evidence, though, indicates reduced levels of glutathione peroxidase 4 can increase life expectancy in mice.
(Answer #1). Peroxidase is an enzyme that can act as a nucleophilic acceptor or electrophilic acceptor. So when potatoes are immersed in a pH of 2, this would be the acidic side of the pH scale.Acids are substances that, when mixed with water, dissociate into hydrogen ions (H+).Answer #1).
