Cell Membrane Themes
8 themes of biology relating to the cell membrane
Science as a process: Science is a process which encompasses many methods in order to reach a final conclusion. This relates to the cell membrane because it carries out many processes to reach a final product. For example, the cell membrane forms a barrier between the inside of the cell and the outside, so that the chemical environments on the two sides can be different. The cell controls those differences to optimize the working of the organelles inside the cytoplasm. The cell also causes brief changes in the internal environment by transporting proteins and other materials across the membrane. These changes are the ways in which the cell responds to its environment. All these functions …show more content…
The cell membrane moves molecules against the concentration gradient from low concentration to high concentration. This function requires energy, or ATP, to carry out the process. At times, the cell membrane uses a protein pump to channel the molecules for easier transport. Two types of active transport the cell completes are antiport and symport. To transport large molecules through the membrane, the cell membrane uses vesicles. Those vesicles transport the material to the necessary organelle which will eventually turn the material into usable …show more content…
It consists of a phospholipid bilayer which acts as a semi-permeable membrane, various proteins which carry out molecule transfer and certain active transport jobs, carbohydrates, and cholesterol. The shape of the cell membrane all depends on the environment inside the cell.
Regulation: The cell membrane regulates the traffic of the cell. It is semi-permeable which means it allows diffusion for only certain molecules. It regulates what enters the cell and defends against diseases that may want to enter the cell as well. It also regulates the shape of the cell and holds it together. The membrane is one of the most important structures in a cell.
Interdependence in nature: The cell membrane not only regulates the traffic of the cell, but is also the liaison for communication outside the cell. The membrane includes receptor protiens which aid in communication between cells. The receptor protiens receive specific chemical signals from neighboring cells or the proteins environment. These signals tell a cell to perform a certain job. It could tell a cell to divide or die, or to allow certain molecules to enter or exit the
