idenify the correct statement regarding enzmes :

Options

A. Enzymes are specific biological catalysis that normally works at high temperauture
B. Enzymes are normally heterogeneous catalysis which decrease the reaction rate
C. Enzymes are specific biological catalysis with low molar masses
D. Enzymes ae specific biological catalysis that are very specific in nature

Answer

To identify the correct statement regarding enzymes, we need to analyze the characteristics of enzymes based on the information provided in the video transcript. Here’s the step-by-step solution:

### Step 1: Understand the Nature of Enzymes
Enzymes are proteins that act as biological catalysts. This means they facilitate and speed up chemical reactions in biological systems.

**Hint:** Remember that enzymes are proteins and their primary role is to catalyze reactions.

### Step 2: Analyze Temperature Conditions
Enzymes typically function at physiological temperatures, which is around 37 degrees Celsius. This is important for their activity and stability.

**Hint:** Recall that physiological temperature is crucial for enzyme activity.

### Step 3: Determine the Type of Catalysis
Enzymes exhibit homogeneous catalysis, meaning that the enzyme (catalyst) and the substrate (reactant) are in the same phase (e.g., both in liquid form).

**Hint:** Homogeneous catalysis involves the catalyst and reactants being in the same phase.

### Step 4: Evaluate Specificity
Enzymes are highly specific biological catalysts. This means that each enzyme typically catalyzes a specific reaction or acts on a specific substrate.

**Hint:** Specificity is a key feature of enzymes; they are tailored to work on particular substrates.

### Step 5: Assess Molar Mass
Enzymes generally have a high molar mass, contrary to the statement that they have low molar mass.

**Hint:** Enzymes are large protein molecules, so they have a high molar mass.

### Conclusion
Based on the analysis, the correct statement regarding enzymes is that they are specific biological catalysts. This aligns with the information provided in the transcript.

### Final Answer
Enzymes are specific biological catalysts.
