Study Notes
Cell Structure and Function
- The cell theory states that all living things are made of cells and new cells are created by old cells dividing.
- Antonie van Leeuwenhoek was the first person to observe and describe bacteria, yeast, sperm cells, blood cells, and the circulation of blood through capillaries.
- Viruses are not considered cells and are parasitic, entering human cells to replicate.
- Cells can be unicellular (made up of one cell) or multicellular (made up of billions of cells working together).
- The cell membrane separates the inside of a cell from the outside environment and regulates the passage of materials in and out of cells.
- Phospholipids, the main component of cell membranes, have a hydrophilic head and a hydrophobic tail and arrange themselves in a lipid bilayer.
- Vesicles are membrane-bound compartments that help move chemicals in and out of cells.
- The plasma membrane is a flexible barrier made up of bilayers of phospholipids that are fluid, not solid.
- Transmembrane proteins in the plasma membrane play roles in transport and signal transduction.
- Hydrophobic bonds stabilize the phospholipid bilayer.
- The plasma membrane selectively controls the passage of small molecules and proteins in and out of the cell.
- Diffusion is the simplest mechanism by which molecules can cross the plasma membrane, either through simple diffusion or facilitated diffusion. Active transport requires energy and is mediated by transporters.
