​​Topic 2: Cell Structure and Subcellular Compartments

LEARNING OBJECTIVES
After completing this lesson, you will be able to:
  • Describe the basic components of cell structure and organelles.
  • Understand the chromatin organization into nucleus.
  • Understand basic mechanisms of cell signaling to respond to changes in the environment.

Topic 2: Key Points
In this section, we explored the following main points:​
  • The characteristics of the cell membrane, such as lipid bilayer and transmembrane proteins are very important for the cell function.
  • The chromatin is  the combination or complex of DNA and proteins that make up the contents of the nucleus of a cell.
  • Cells have proteins called receptors  that are important to receive extracellular signals and initiate signaling pathways in the cell.
