Who's it for?
This chapter of our high school biology tutoring solution will benefit any student who is trying to learn about cell communication and earn better grades. This resource can help students including those who:
- Struggle with understanding signal reception, cell transduction, cellular response or any other cell communication topic.
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their cell communication unit
- Cope with ADD or ADHD
- Want to get ahead in high school biology
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about cell communication simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about cell communication on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Explain how cells communicate with one another.
- Discuss signal reception and transduction in cells.
- Describe how signal transduction pathways are used in cell communication.
- Explain how cells respond to signals.
1. An Overview of Cell Communication
Cellular communication is an important process that allows cells to pass signals to one another. In this video lesson, you will be introduced to the process of cellular communication, identifying the three steps of cellular signaling in organisms.
2. Signal Reception in Cells
Our cells 'talk' to each other all the time through chemical signals. The first step of this process, reception, is a critical component. In this video lesson you will learn about this step in cell communication as well as understand its overall importance.
3. Transduction in Cells
Once a cellular signal is received, a chain of events begins that helps the receiving cell decode the signal. In this video lesson you will learn about this second step of cellular communication and its importance to the overall process.
4. Cellular Responses to Signals
After reception of a signaling molecule and movement of that signal through transduction, the cell can now respond. There are different types of cellular response as well as different mechanisms the cell uses to make this process more efficient.
5. What Are Endorphins? - Definition, Types & Function
Endorphins are chemicals in the brain that act as natural analgesics. Athletes may know them as the cause of runner's high. Learn more about these natural painkillers and quiz yourself when you are done.
