An obligate parasite, or holoparasite, is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host. If an obligate parasite cannot obtain a host it will fail to reproduce.
They are called obligate intracellular parasites because they must use a host cell's amino acids to synthesize proteins, metabolic enzymes and pathways to obtain energy, ribos â¦ omes to synthesize proteins, and nucleotides for transcription and replication.hey are obligate in the sense that they cannot replicate outside of a host cell. To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machi â¦ nations of said cell (parasitic behavior) and then copy itself. 24 people found this useful.
