The low status of smell in Western culture is reflected in our language: colloquial terms for ânoseâ, for example, are almost all derogatory, or at the very least disrespectful (schnozzle, conk, hooter, snoot, snout, etc.) â and large or distinctive noses are considered ugly.
Ribosomes are organelles composed of ribosomal proteins (riboproteins) and ribonucleic acids (ribonucleoproteins). The word ribosome is made from taking â ribo â from ribonucleic acid and adding it to â soma â, the latin word for body. Ribosomes are bound by a membrane but they are not membranous.
Ribosomes on the rough endoplasmic reticulum are called âmembrane boundâ and are responsible for the assembly of many proteins. This process is called translation. Certain cells of the pancreas and digestive tract produce a high volume of protein as enzymes.t is âsmoothâ because it is not studded with ribosomes and is associated with smooth slippery fats. CELLS NEED THE ROUGH AND THE SMOOTH. Think of a cell as a âmultitude of membranesâ we said in an earlier section. This statement certainly applies to the endoplasmic reticulum an organelle found in eukaryotic cells.
