Chlamydomonas

a flagellate, unicellular green alga now normally placed in the division CHLOROPHYTA but in many (older) texts regarded as a protozoan and placed in the class MASTIGOPHORA. It is characterized by the presence of two flagella (see FLAGELLUM and, because of the presence of CHROMATOPHORES (1), is referred to as a phytoflagellate (often given subclass status: Phytoflagellata). Reproduction is by repeated fission or varies between species from an asexual method to a sexual method of CONJUGATION where ISOGAMETES rather than differentiated male and female gametes are produced.

In the Iceland scallop Chlamys islandica, a decrease in the amount of glycogen in the adductor muscle reduced the number of binding sites for the key glycolytic enzyme glycogen phosphorylase, which may explain this scallop's lower activity levels (Brokordt & Guderley 2004a).
