Mechatronics Rendering of Cellular Active Transport: Sodium-Potassium Pump

This PowerPoint presentation showcases a visual model of the sodium-potassium pump demonstrating conformational changes in membrane proteins during active transport. It delves into cell membrane structure, receptor proteins, and the sequence of events, using components like LEDs, capacitors, and servo motors. The project aims to enhance understanding of biological processes through engaging Mechatronics, making complex concepts tangible for students.

  1. PowerPoint Presentation Mechatronics Rendering of Cellular Active Transport (Sodium-Potassium Pump) SUMMIT PROGRAM July 16 - August 10, 2007` By: HAROLD MEISELMEN Clara Barton High School ANALIE NARCA Philippa Schuyler Middle School for the Gifted and Talented (I.S.383)

  2. MECHATRONICS BIOLOGY (cell membrane) & (cell membrane) BIOLOGY

  3. Mechatronics Rendering of Cellular Active Transport (Sodium-Potassium Pump)

  4. PROJECT GOALS • To provide a visual model and demonstration of the sodium-potassium active transport pump • . To show the conformational change in the membrane protein during cellular active transport

  5. CELL MEMBRANE STRUCTURE & FUNCTION RECEPTOR PROTEIN TRANSPORT PROTEIN MARKER PROTEIN

  6. SEQUENCE OF EVENTS

  7. BOE Basic Stamp LED Capacitors Microprocessor Push Button Resistors Jumper Wires Servo Motor` USB Cable PARTS AND COMPONENTS

  8. PARTS AND COMPONENTS CONTROL DEVICE Servo motor Servo motor controls the closing - opening of cell membrane Protein, ATP and sequence of events.

  9. Used as K+ ions Used as ATP Used as Na+ ions Used as the intracellular And extracellular fluids PARTS AND COMPONENTS Light Emitting Diode Green LED Red LED Yellow LED

  10. LED CIRCUIT PIN 1.

  11. SERVO CIRCUIT • Pin 13 servo 2 - ATP binding site on protein • Pin 14 servo 1 - Protein channel • Pin 15 servo 3 - Caption- steps of the process Vin White P14 Red Servo Black Vss

  12. HOW IT WORKS? • Na+(Red LED)ions attracted to the binding site of protein • 3 Na+(Red LED) bind to protein • Protein changes shape exposing ATPbinding site • High-energy phosphate(Yellow LED) attaches to the protein • Protein changes shape exposing Na+(Red LED) to the outside of cell and the 3 sodium ions are released • 2 K+ ions(Green LED) attach to the protein • High-energy phosphate(Yellow LED) is released from the Protein Binding site • Protein channel returns to its original shape bringing the K+ ions (Green LED) in to the cell

  13. The IMPORTANCE OF MECHATRONICS IN TEACHING BIOLOGICAL CONCEPTS • By using Mechatronics we would be able to : • explain biological processes in an engaging way for students • make complex concepts in biology tangible and easier to understand • allow student’s participation through manipulation and control of Mechatronics rendering of certain biological concepts (future development) • show the use and potential of Mechatronics in the teaching and learning process not only for Science and Math but also for other subject areas .

  14. NEXT STEP • Expansion of the use of the model by increasing interactivity, including manipulation of ion and ATP concentrations, showing the effect of chemicals on the process. • Use of this model to further explain the role of this process in muscular contraction and nerve impulses conduction.
