Journal Entry:

What is the difference between passive and active transport across the membrane? #137-138 in 500 AP Questions to know before AP Exam.

Learning Intentions  

• We will learn how to construct models that connect the movement of molecules across cell membranes with membrane structure and function.
• We will learn how to use models to analyze situations to determine how certain molecules get across the cell membrane and what components of the membrane participate in the transport.
• We will learn how to determine if a cell is isotonic, hypertonic or hypotonic in various situations you model.

Closing Task:

You can model cellular transport using yourself and your classmates and be able to explain each component in the process as well as properties of that component

You can model passive transport, active transport, exocytosis and endocytosis across the cell membrane.

Content Standards being covered:

Topics:
ENE-2.C   Explain how the structure of biological membranes influences selective permeability
ENE-2.D  Describe the role of the cell wall in maintaining cell structure and function.
ENE-2.E  Describe the mechanisms that organisms use to maintain solute and water balance.
ENE-2.F  Describe the mechanisms that organisms use to transport large molecules across the plasma membrane.
ENE-2.G  Explain how the structure of a molecule affects its ability to pass through the plasma membrane.
