Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.

![Diagram Explanation]
The provided diagram illustrates a fundamental concept in biochemistry involving an enzyme interacting with substrates. The sequence proceeds as follows:
1. **Left Image**: A red structure with a concave depression on the top, representing an enzyme, is shown. An arrow points towards the enzyme's active site, indicating the direction of substrate binding.
2. **Center Image**: The enzyme (red structure) now has two different shapes (blue and orange hexagonal figures) bound to its active site. This stage signifies the enzyme-substrate complex formation.
3. **Right Image**: Post the enzymatic reaction, the two different shapes (products) are released from the enzyme. The enzyme retains its original form, ready to bind with new substrates.
**Multiple Choice Options:**
- **enzyme**
- **product**
- **substrate**
- **active site**
The red image in the center picture represents the **enzyme**.
This content explains the lock-and-key model of enzyme action, where the enzyme's active site (red structure) binds specifically to substrates (blue and orange shapes) to form an enzyme-substrate complex and then releases products. The diagram visually aids in understanding the process of enzyme catalysis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fff017809-0f04-4ead-8eb3-41912d677308%2F7f00a2ae-8cd0-427c-a486-7c97c2ad47f3%2F3hs7g4_processed.jpeg&w=3840&q=75)
