Carrier proteins and channel proteins are both involved in cell transport across the plasma membrane. Their functions, similarities, and differences are described in this resource. Includes examples for active, facilitated, and passive...

[Free Registration/Login may be required to access all resource tools.] Cells are found in all different types of environments, and these environments are constantly changing. For example, one-celled organisms, like bacteria, can be...

This comprehensive study guide covers the main terms and concepts needed for a unit on cell transport and homeostasis.

Students will be able to identify two ways that molecules and ions cross the plasma membrane.

Young scholars participate in a simulation which shows the movement of molecules across a cell membrane so that they understand passive and active cell transport. Students also use computational thinking skills by developing systems...

This resource is an article about the cell membrane, and its role in water and solute movement in and out of the cell.

This is an article about tubular reabsorption including what it is; how reabsorption in the nephrons works; and reabsorption of sodium, nutrients, water, and other ions.

Review the major points about active transport.

Brief overview of the transport mechanisms involved in cell transport.

Explanation of cell membranes and the way selective materials may move through them.

[Free Registration/Login may be required to access all resource tools.] In this activity students will learn about facilitated diffusion and the role of transport proteins, channel proteins, and carrier proteins.

In this module, students discover how each cell is organized to complete the function of producing and transporting proteins, and how cells relate to homeostasis of the body.
