Question

labels ① drop zones ← reset all substrate active site enzyme - substrate complex binding site products enzyme image description

Explanation:

To solve this enzyme - substrate interaction diagram labeling:

1. The first empty box (connected to the substrate - like shape) should be labeled "Substrate" (but wait, no, the left - most empty box connected to the orange shape (substrate) when it's approaching the enzyme: Wait, the blue shape is the enzyme. The area on the enzyme where the substrate binds is the "Active site" or "Binding site"? Wait, the "Binding site" is part of the active site. Wait, let's recall the enzyme - substrate cycle:

• The enzyme (blue) has a region called the Active site (or Binding site) where the substrate (orange) binds. So the box pointing to the enzyme's binding region is "Active site" (or "Binding site").
• Then, when the substrate is bound to the enzyme, that complex is the Enzyme - substrate complex (the middle blue - orange complex).
• Finally, after the reaction, the products are formed, so the box with the red and yellow shapes (products) should be labeled "Products".

Let's go step by step:

• The first empty box (left, connected to the orange substrate - like shape before binding? No, wait the left - most empty box is connected to the orange shape (substrate) when it's near the enzyme. Wait, no, the labels are: Substrate, Active site, Enzyme - substrate complex, Binding site, Products. Wait, the enzyme (blue) has a "Binding site" (or "Active site") where the substrate binds. Then the complex of enzyme and substrate is "Enzyme - substrate complex". Then the final products are released.

So:

• The box pointing to the enzyme's binding region: "Active site" (or "Binding site").
• The box pointing to the enzyme - substrate complex (blue with substrate and then with products? Wait, the middle blue shape with the substrate (orange) bound is the "Enzyme - substrate complex". Then the next box with the red and yellow (products) is "Products". And the last empty box (top right) is for "Products" as well? Wait, no, let's re - visualize:

1. The orange shape is "Substrate".
2. The blue enzyme has a region (the empty box pointing to the enzyme) which is the "Active site" (where substrate binds).
3. The complex of enzyme and substrate (blue + orange) is "Enzyme - substrate complex".
4. After the reaction, the products (red and yellow) are formed, so the box with red and yellow is "Products", and the top - right empty box is also for "Products" as they are released.

Answer:

• The box pointing to the enzyme: "Active site" (or "Binding site")
• The box pointing to the enzyme - substrate complex: "Enzyme - substrate complex"
• The box with the red and yellow shapes (and the top - right box): "Products"
