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.
The Golgi apparatus retrieves proteins carried in vesicles made in the endoplasmic reticulum. The organelle then modifies these proteins by chopping off some sections or adding necessary molecules. A vesicle then forms around the protein, pinches off of the Golgi apparatus and travels to where the protein is needed.
