Branches of Biology
Transport Protein Definition Transporter proteins are proteins that transport substances across biological membranes. Transport proteins reside within the membrane itself, where they form a transport channel or mechanism to allow their substrate to move from one side to the other. The substances carried by these proteins can include ions such as sodium and potassium; Sugars … Read more
Glycogenolysis definition Glycogenolysis is the breakdown of the glycogen molecule into glucose, a simple sugar that the body uses for energy. Glycogen is essentially energy stored in the form of a long chain of glucose, and glycogenolysis occurs in muscle and liver cells when more energy needs to be produced. The opposite of glycogenolysis is … Read more
Human Genome Project: what is it and what applications does it have? The first genetic studies date back to the 19th century, long before we knew what genes were. By growing peas ( Pisum sativum ) with different characteristics, the Augustinian monk Gregor Mendel was able to elaborate on the so-called laws of inheritance, which describe how some characters are … Read more
Active transport definition is the process by which energy is used to move substances in, out of, and between cells. In some cases, the movement of matter can be done by passive transport that does not consume energy. However, the cell often has to transport the materials against their concentration gradient. In these cases, active … Read more
Define Diffusion is a physical process that refers to the net movement of molecules from an area of high concentration to an area of lower concentration. The diffusing material can be solid, liquid or gaseous. Likewise, the medium in which the diffusion takes place could be in one of three physical states. One of the … Read more
What are Eosinophils? What are Eosinophils? Eosinophils are mobile phagocytic cells that play an important homeostatic role in defense against parasitic infections. Eosinophils are bone marrow-derived granulocytes that remain in the bloodstream for a shorter period and reside primarily in tissues. The functions of eosinophils are multifaceted, including antigen presentation, peptide release, lipid, and cytokine … Read more
What are chromosomes? Chromosomes are the highly organized structures inside biological cells, made up of DNA and other proteins, and where most of an individual’s genetic information resides. They have a definite X shape, which is perfectly observable during the stages of cell division or replication ( meiosis or mitosis ). Each chromosome has a characteristic … Read more

What is bilirubin? Bilirubin Test, And Urine Bilirubin Test What is bilirubin? Bilirubin is a molecule formed by the breakdown of red blood cells and other cells with porphyrins. Red blood cells carry special molecules, called hemes (a type of porphyrin), that house an iron atom. This arrangement allows red blood cells to carry oxygen. When blood cells break down, … Read more
What is biotechnology? Biotechnology is the branch of science which deals that gained popularity in the 1970s, a science that explores organisms, cells, and cellular components to develop new technology through various biological processes. Biotechnology proves very useful in the field of agriculture, medicine, industry, and environmental studies. If I can explain in other easy … Read more
