What is receptor mediated endocytosis? Explain how it occurs. Receptor meditated endocytosis is a way the cell uses endocytosis by absorbing coated vesicles by the means of clathrin and breaking down the absorbed materials so the cell can use it. Receptor mediated endocytosis begins by the binding of a protein to a receptor that is located on the plasma membrane. Next the receptors collect and cluster in coated pits‚ and then forms a vesicle.(pg. 343) Then adaptin binds to the receptor and clathrin

Receptor-mediated endocytosis Receptor-mediated endocytosis is an important mechanism the body uses to remove cholesterol from the bloodstream. Persons with the inherited disease hypercholesterolemia lack normal LDL receptors and as a consequence‚ have dangerously high levels of circulating cholesterol. Their cells cannot remove circulating LDL particles‚ and so the load of cholesterol tends to accumulate on the walls of their arteries‚ which eventually blocks blood flow. Mammalian cells use receptor-mediated

Look at Merton’s Modes of Adaptation. Give at least one example of how someone‚ perhaps someone in the criminal justice system‚ uses each mode. Robert K. Merton’s "Social Structure and Anomie" (1938). People adapt in many different ways. Just as part of a river that suddenly finds it‚ self blocked by an obstacle and may split and find a new way to the ocean. Merton outlines five ways in which people adapt to society’s goals and means and they are as follows: 1) Conformity - Adherence to the practices

As stated above the androgen receptor-coding gene is located in band Xq11-q12 on the long arm of the (X) chromosome. This portion of the X chromosome is about 90kb and contains 8 exons that code 919 amino acids with a mass of approximately 110kDa. These many amino acids determine the structure of the transcription factor protein involved in steroid-hormone activation. The androgen receptor has several functional domains‚ which are inconsistently classified among various literature. In general the
