There are three types of unsaturated hydrocarbons: alkenes, alkynes and aromatic hydrocarbons. Alkenes have one or more carbon-carbon double bond. Alkynes have one or more carbon-carbon triple bond, and aromatic hydrocarbons have a benzene or aromatic ring in their structure.ydrocarbons 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.
In eukaryotes the organelles of the endomembrane system include: the nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes and the cell membrane.
C) In eukaryotic cells, internal membranes form membranous compartments called organelles. D) In eukaryotic cells, internal membranes contain proteins essential for metabolic processes. E) In eukaryotic cells, internal membranes standardize the internal environment of all cellular organelles. 23) You are told that the cells on a microscope slide are plant, animal, or bacterial. microscope and see cell walls and membrane-bound organelles.
