The cellular biology is a wide and versatile area of research. Your mind cannot imagine the huge number of chemical reactions that take place inside the cell. Each cell is comprised of organelles which each has a special function related to its unique structure. Each...
Overview of cell biology
By: Tarek Musslimani
In this article I will discuss the biology of the cellular membrane and the biology of the organelle inside the cell, which is called the mitochondria. In addition, I will discuss the important process of protein trnaslation which occurs on the cellular ribosomes. The cell...

Active transport across the cellular membrane refers to a process in which ions and some molecules are actively transported from one side of the cell to the other side of the cell membrane. This process is referred to as active because it transports molecules and...

In the human body, the cavities within including passages and tubules along with the external surface of the skin are lined by a specialized tissue structure known as the epithelium. Although these epitheliums can vary from place to place depending on the functional adaptations, they...

-Overview An epithelium is a layer of cells that are connected or arranged side by side in order to form a surface lining of a fluid or air filled tube, cavity or else a surface that is exposed to the outside, such as skin. These...
Types of energy production in human cells
By: Tarek Musslimani
In this article, I will discuss methods for the generation of energy in the body that are used by the various body tissues. These methods include aerobic respiration and anaerobic respiration in addition to the generation of energy in muscle tissue which is different than...
Health benefits of phospholipids
By: Saher Naseem
Human cells possess implausibly complexed structure and made up of many compounds, among them a group of essential fats called phospholipids. A sophisticated and refined combination of essential phospholipids (EPL) comprises of phosphotidyl Choline (lecithin), phosphotidyl Serine, phosphotidylethanolamine, phosphotidylinositol, in addition to linoleic and linolenic...

Insulin is a protein hormone which is secreted by the islet cells of the pancreas. Chemically speaking it is composed of two polypeptide chains that are connected by disulfide bond or S-S bond. It has a molecular weight of 5808. Although insulin is known for...
Biology class activity: Eukaryotic cell structure
By: aggieteacher
As a Biology teacher, one of the things that I deem critical for students to leave my class knowing is the structural components (and their functions) of a eukaryotic cell. Eukaryotic cells are cells that have a nucleus and membrane bound organelles. These can be...

Phospholipids are a type of lipid (a lipid being a fat, a sterol, or a wax among other things), which constitute a major part of a cell membrane. Most phospholipids are made up of two fatty acid molecules (hydrophobic end) and a glycerol (hydrophilic end)...
