Active Transport Protein

Although not actual size, this active transport model is the ideal tool for teachers to demonstrate to students how molecules are moved against their concentration gradients through a membrane into a cell. This product represents the process of an active transport protein transporting molecules from a low concentration to a high concentration. When a cell needs to maintain a high concentration of one substance and/or a low concentration of another, these substances must be moved against their natural flow, which means normal diffusion through a membrane will not work and an active transport protein is needed. These special proteins bind to specific substances, close the openings on one side of the membrane, and create new openings on the other side. In order for these proteins to change shape, exergonic energy from the breakdown of adenosine triphosphate into adenosine diphosphate and a single phosphate is required. This whole process is referred to as Active Transport. As a student, I understand the struggle teachers face when trying to illustrate this complex concept in a way students can comprehend. That's why I created this model - to be an aid for both teachers and students. I highly recommend printing this design. Students will excel in class with this model, which brings the textbook to life. This model is made up of 25 printed pieces (12 different types), a piece of wood, and two types of magnets. After a long time spent printing, hand adjustments, sawing, taping, and gluing must be done according to the directions below.
