About This Simulation
Discover the structure and function of cell membranes by launching cargo molecules at a virtual cell. Apply your learning back in the lab to improve the health of synthetic cells that the lead researcher wants to use to produce insulin.
Learning Objectives
- Describe the plasma membrane structure using the fluid mosaic model
- Recognize the relative permeability of lipid bilayers to different classes of molecules
- Compare active and passive transport of molecules
- Identify the 3 modes of active transport and the different classes of ion channel and carrier molecules
- Relate the expression of specific transport proteins to the cell's role

Learn More About This Simulation
Join Dr. B.I.O. Hacker in her synthetic biology lab, where she wants to change the world! In this simulation, you will learn about the structure and function of the cell membrane and discover why membrane transporters are vital for healthy cells and the function of organ systems.
The synthetic biology lab
Your mission begins in the synthetic biology lab. Here you will meet Dr. Hacker, who will introduce you to the concept of selective permeability and the fluid mosaic models of the plasma membrane. Together, you will explore why cells need specialized transporter proteins to transport cargo molecules across their membranes.
Transport molecules into a virtual cell
Next, you will teleport to a virtual cell, where you will explore how different types of molecules can cross the cell membrane. While some molecules are able to diffuse across the cell membrane, most molecules require a transporter protein to enter or leave the cell. Explore the different channels, carriers, and pumps that exist in the membrane and how they ensure that only the right molecules enter under the right conditions.
Apply your knowledge
Return to the lab to test whether inserting a transporter protein in the membrane would help certain molecules to enter the cell. To do so, you will set up a fluorescence microscopy experiment to measure transport in living cells. Finally, discover how some transporter proteins do not only keep the cell healthy but also help organ systems to function. From filtration in the kidneys to the contraction of muscles during exercise, membrane transport contributes to many processes. Can you find out how?

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

Labster can be integrated within a school's LMS (Learning Management System), and students can access it like any other assignment in their LMS. If your Institution does not choose an LMS integration, students will log in to Labster's Course Manager once they have an account created. Your institution will decide the access method during the sales process.
Labster is only available for purchase by faculty and administration at academic institutions. To procure Labster, simply reach out to us on our website. Schedule a demo, book a meeting to discuss pricing, start a free trial, or simply fill out our contact form.
Labster simulations are created by real scientists and designed with unparalleled interactivity. Unlike point and click competitors, Labster simulations immerse students and encourage mastery through active learning.
Labster supports a wide range of courses at the high school and university level across fields in biology, chemistry and physics. Some simulations mimic lab procedures with high fidelity to train foundational skills, while others are meant to bring theory to life through interactive scenarios.
