EOG8GF5W1 GO:0005886 1/25 plasma membrane cellular_component "The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins." [ISBN:0716731363] EOG8GF5W1 GO:0007608 1/25 sensory perception of smell biological_process "The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors. This is a neurological process."
