Cell Biology - BSC110

Home Study Cytology Course

Cell biology is an introductory course designed for everyone wanting to learn more about biology. This is a foundation course for those wishing to have a career in health sciences, biology and biochemistry. Upon completion of this course students should have a sound understanding of cell structure and processes.

Duration: 100 hrs

Extract from course:

"The word cell is derived from the Latin “cella” which means “small room”. Cells are the units from which all living organisms are built. Some organisms (e.g. bacteria) have only one cell in the entire organism. Others are multicellular. A human body can contain an estimated 100,000 billion cells.

Each cell is a self-contained and partially self-sufficient compartment designed to carry out a limited series of functions. While the structure and function of cells is extremely variable, their basic structure is similar. All cells are bound by an outer membrane and contain cytoplasm and DNA."

The food we eat must be broken down into smaller molecules before they are available to cells.  Obviously we do not want to break down our own cells, therefore it must occur outside the cells in a process called digestion which occurs in our intestines or in specialised organelles called lysomes. Both of these processes are involved in breaking down large molecules into their base constituents such as proteins are broken down into amino acids and polysaccharides into sugars.  When broken down these molecules may enter the cell where oxidation of the molecules can occur in the cytosol. 
In the cytosol the molecules undergo oxidation, whereby glycolysis further breaks down glucose into two molecules of pyruvate.  Other sugars are also broken down into pyruvate however they must first be altered to fit into the glycolytic pathway.  As a result, three energy carrying molecules are formed, they are 2 ATP and NADH.  

Formation of Acetyl CoA
The pyruvate formed can then enter the mitochondria.  In the mitochondria the pyruvate is converted into two acetyl groups and CO2.  An acetyl group is attached to Coenzyme A to form Acetyl CoA (remember this is another energy carrying molecule). 

Lipids also form large amounts of Acetyl CoA. Hydrolysis involves splitting three fatty acid molecules from a glycerol molecule. (NB: Fatty acids are simply long carbon chains with hydrogen ions.) When this happens Acetyl CoA can be produced.

Mitochondrial Processes
As mentioned above Acetyl CoA if formed by the breakdown of glucose, lipids and amino acids, Acetyl CoA is an easily transferable high energy chemical group.    In the mitochondria this group is transferred to oxaloacetate, after this the acetyl group can enter the Citric Acid Cycle (also known as the Kreb’s Cycle).

The Kreb’s Cycle
It is named after Hans Krebs, one of the first scientists to study this process. This is a very important cycle in the cell and it accounts for the major portion of carbohydrate, fatty acid and amino acid oxidation and it is also the source of numerous biosynthetic precursors. It is therefore an amphibolic (both anabolic and catabolic) pathway and one that the cell has to regulate very carefully.
