#XL - Q Biochemistry

Two types of plant peroxisomes:

Present in leaves - participates in photorespiration.

Present in germinating seeds (glyoxysomes) - converts fatty acids into sugars.

Catalase uses the H2O2 to oxidize a variety of other substrates (formic acid, formaldehyde, and alcohol) by the “peroxidation” reaction.
