Hydrocarbons are compounds that only consist of the elements hydrogen and carbon. In this lesson, we will focus on one type of hydrocarbon: unsaturated hydrocarbons, and its three types-alkenes, alkynes and aromatic hydrocarbons.ydrocarbons are compounds that only consist of the elements hydrogen and carbon.

Ribosomes are the organelles responsible for protein translation and are composed of ribosomal RNA (rRNA) and proteins. Some ribosomes are found in the cytoplasm, a gel-like substance that organelles float in and some are found in the rough endoplasmic reticulum.
Ribosomes are the smallest organelle in a cell, but they have a big job. They are made of two subunits, a large and a small, and they perform protein synthesis.Protein synthesis is where RNA comes into a ribosome after copying DNA.he rough ER also attaches things to proteins and is the main source of transportation of proteins from the ribosomes to the Golgi body, where they will be shipped all around the cell. They could also be shipped straight from the rough ER to the cell membrane, where the proteins can be shipped out of the cell.
