Question

Create your own model of a metabolic reaction involving an enzyme and two substrates. choose materials from your environment (school or home) that can be molded, cut, or otherwise altered to create a model of an enzyme doing its work. in your model, be sure you to demonstrate the specialized "lock and key" fit that the enzyme has with the substrates. label the parts of you model—substrates, enzyme, enzyme/substrate complex, and product(s).

Answer 1

To create a model of a metabolic reaction involving an enzyme and two substrates, use materials like clay or play dough. Shape an enzyme and substrates, ensuring they fit like a lock and key. Attach the substrates to the enzyme to create an enzyme-substrate complex, then mold the complex into the product.

Step-by-step explanation:

To create a model of a metabolic reaction involving an enzyme and two substrates, you can use materials like clay or play dough that can be molded and altered. First, create one piece of clay or play dough in the shape of an enzyme and another two pieces representing the substrates. Make sure the shape of the active site of the enzyme can fit the substrates like a lock and key. Attach the substrates to the active site to form an enzyme-substrate complex. Finally, mold the complex into the product(s) that are formed by the reaction.

Answer 2

A playdough model depicting an enzyme (a shaped piece), substrates (fitting shapes), and their connection with toothpicks illustrates the "lock and key" specificity of enzyme-substrate interaction in a metabolic reaction.

For this model, we'll use playdough or modeling clay, as they are moldable and can represent different components of the reaction.

Materials:

1. Playdough or modeling clay (different colors)

2. Toothpicks or small sticks

Model Components and Steps:

1. Enzyme:

- Take one color of playdough to represent the enzyme. Mold it into a specific shape, like a lock or key, to depict the active site.

2. Substrates:

- Use another color of playdough to represent two different substrates. Mold them into shapes that can fit into the active site of the enzyme (like a puzzle piece).

3. Enzyme-Substrate Complex:

- Demonstrate the "lock and key" fit by placing the substrates into the active site of the enzyme. Show how they fit snugly, illustrating specificity.

4. Reaction:

- Connect the substrates in the active site using toothpicks to show the enzyme-substrate complex. This represents the binding of substrates to the enzyme's active site.

5. Product:

- Once the reaction occurs, modify the substrates or use a different color of playdough to represent the products formed after the reaction.

Label each part of the model accordingly—Enzyme, Substrates, Enzyme-Substrate Complex, and Products—to clearly illustrate the metabolic reaction.

This model visually represents how the enzyme's active site (enzyme) perfectly fits the substrates, forming the enzyme-substrate complex, facilitating the reaction, and resulting in the formation of products. The specificity of the enzyme's active site for its substrates is demonstrated through the "lock and key" fit, showcasing how enzymes catalyze reactions in biological systems.
