The Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi. Characteristics of Protists: mostly unicellular, few multicellular, eukaryotic, can be heterotrophic or autotrophic.Ex: algae, Paramecium, kelp (multicellular). î î î.he Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi.

The active metabolites of codeine, notably morphine, exert their effects by binding to and activating the Î¼-opioid receptor. This occurs because opioids structurally mimic endogenous endorphins which are naturally found within the body and also work upon the Î¼-opioid receptor set.
Hydrocodone and codeine are NOT the same chemical compound; they're two different drugs. Codeine is the 3-methylether of morphine. It's almost inactive on it's own, and need â¦ s to be converted into morphine via the enzyme CYP2D6 in the liver to cause opioid effects, hence it's a prodrug.
