About This Chapter
Cellular Processes - Chapter Summary
These interactive lessons will boost your knowledge of cellular processes. Get familiar with energy transfer in the cells, comparing chemosynthesis and photosynthesis, and light reactions and photolysis. Lessons cover information about:
- Cell cycle
- Reactions during photosynthesis
- Calvin-Benson cycle
Each lesson focuses on one aspect of cellular processes subject matter. Videos are 5-10 minutes long. If you want to replay any part of the lesson, you can use the accompanying transcript or the video timeline tool to go right to the section you want to watch again. You can submit a question directly to the instructor.
1. The Cell Cycle: Definition, Phases & Sequence
Learn about the dividing and non-dividing states of the cell and discover the different phases of the cell cycle, including interphase, cytokinesis, and the stages of cell division.
2. Meiosis: Comparison to Mitosis, Crossing Over & Process
Welcome to meiosis, a realm of division doubled for reproduction untroubled. You'll get a preview of both divisions of meiosis and see what it takes to go from a diploid cell to a haploid gamete.
3. Cellular Respiration: Energy Transfer in Cells
Watch this short video to learn the basics about converting organic compounds into ATP, also known as cellular respiration. We'll look at an overview of the process.
4. Photosynthesis: Definition & Reactions
Some people may falsely assume plants to be weaker than animals. However, plants and a few other organisms harness light energy from the sun to feed the rest of us. This lesson will introduce you to how they do it.
5. Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products
In this lesson, we'll learn how electrons get excited during the light-dependent reactions of photosynthesis, jumping off photosystem reaction centers like they were trampolines! In addition, we'll learn how the splitting of water creates reactants for this part of photosynthesis while creating a little fresh air for us.
6. Dark Reactions of Photosynthesis: The Calvin-Benson Cycle
Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.
7. Chemosynthesis: Definition & Equation
This lesson introduces the concept of chemosynthesis. It explains that energy is necessary for all life and provides a description of the chemosynthetic process. The lesson also includes examples of where chemosynthesis occurs in nature along with a brief quiz.
8. Differences Between Chemosynthesis & Photosynthesis
We all make food in different ways, and the same goes for bacteria, plants, and algae. This lesson goes over the two ways by which such organisms produce food: chemosynthesis and photosynthesis.
