ATP as Cellular Energy
In this seminar you will read closely and analyze the structure of ATP- Adenosine Triphosphate. You will curate your own information about the importance of ATP in a cell by listening and reading text as to what the experts have to say. By modeling the function of ATP in an inquiry lab you can accurately identify the various levels of cellular work done by Adenosine Triphosphate.

Can you name the three molecules use to build Adenosine triphosphate?
Can you compare AMP, ADP and ATP?
Can you remember what force two similar charges will enact upon each other?
Which phosphate do you think is the unstable one due to the force of two negative charges?
Which bond is most likely to break to release energy?
Read or watch the resources to learn about this concept, then do the practice activity.
Adenosine Triphosphate (ATP) is the only molecule that is used for direct cellular energy. Its unique structure allows the cell to utilize this chemical to carry out all cellular processes such as homeostasis, transport, and cellular movement that translates to the movement of the entire organism. How can such a simple molecule pack such a punch? Let’s find out. Choose some of the following ways in the explore section to learn about the structure of ATP and its function in biological systems.

Time to launch! In this inquiry lab, you will be modeling how launched projectiles model ATP and cellular work in the cell.
What’s up with ATP?
Background: ATP is the molecule responsible for providing most cells with energy. It is a molecule that consists of adenine, ribose sugar, and three phosphate groups. The energy is stored in the bond of the last or terminal phosphate group. Energy is essential for all life forms. Energy is needed to do work, while work, by definition, is the ability to apply a force over a distance. Many cellular process require the movement of particles or chemical compounds from place to place. Multicellular organisms require the working of thousands of cells moving together to perform functions.

1- Determine the amount of energy needed to perform work of various cellular functions.
2- Simulate the regeneration of ATP from ADP.
Purpose: Targets with varying amounts of mass are set up and each is labeled with the cellular work being done. It is your job to determine how much ATP is required to knock over each target. Before energy can be released to do work from your launcher (ATP), it must have all three phosphates to represent ATP. Only the terminal or last projectile (phosphate group) can be used to release energy from the bond or launcher. Regeneration must happen before energy is released again.
Task: Design an experiment to determine how much energy from ATP it takes to knock down the various massed targets. You will use a nerf launcher to model the ATP---> ADP molecules.
Pre- lab Discussion:
How does the “atom blaster” model an ATP molecule?
Relate the structure of the “atom blaster” to the structure of the ATP molecule.
Determine how potential energy (energy of position) can be converted to kinetic energy (energy of motion) in this model.
Create a list of steps for your designed experiment.
Design a table used for data collection. Each variable will need to be identified. Determine how many trials are needed and report data as averages.
Create a graph of data showing the variables (independent and dependent) along with units.
All diagrams must be labeled.
Summarize how your experimental design modeled ATP.
Reflect on the data. Is there another way to collect data to show the work ATP does in cellular processes?
How does your experimental design affect the outcome measured? Can this lead to invalid data? Explain.
Conclusion: Use your results to share your conclusion with the class; be sure to make the connection between ATP and cellular work. An image (diagram) must be included.
