Key Topics Covered in BIOL 11900:
Exploring the Intricacies of Cellular Structures:
Cells are remarkable entities with complex structures that enable their functions. The nucleus, often referred to as the “control center,” houses the genetic material that carries the instructions for cellular activities. The cell membrane acts as a barrier, controlling the exchange of substances between the cell and its surroundings. Organelles, such as mitochondria and endoplasmic reticulum, have specific roles in processes like energy production and protein synthesis. Furthermore, cellular transport mechanisms allow the regulated movement of substances in and out of cells, ensuring proper function.
Understanding Cellular Processes and Energy:
In this section, we explore the processes through which cells obtain and utilize energy. Photosynthesis, carried out by plants and some microorganisms, converts sunlight into chemical energy stored in glucose. Cellular respiration then releases this energy from glucose, producing ATP as the main source of cellular energy. Students gain insights into the metabolic pathways involved in energy production and the crucial role of enzymes in catalyzing these reactions.
Cellular Reproduction and Division:
Cellular reproduction is essential for the growth, repair, and reproduction of organisms. The cell cycle, a series of events, regulates the orderly progression of cells from birth to division. Students learn about the checkpoints that monitor the integrity of DNA and ensure accurate replication. Mitosis allows for the growth and maintenance of body tissues, while meiosis is responsible for the production of gametes and genetic diversity.
