All the following are correct about enzymes, except:

Options

A. Lower the energy of activation of reaction
B. Make the equilibrium more favourable for the organism
C. Lower the energy of product and increases the energy of reactant .
D. Are altered permanently in the reaction they catalyse

Answer

To solve the question, we need to analyze the statements provided about enzymes and identify which one is incorrect. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand what enzymes are
Enzymes are biological catalysts, primarily proteins, that speed up chemical reactions in the body by lowering the activation energy required for the reaction to occur.

**Hint:** Remember that enzymes are proteins that catalyze reactions by lowering activation energy.

### Step 2: Analyze the first statement
The first statement claims that enzymes lower the energy of activation of the reaction. This is a true statement because enzymes indeed lower the activation energy, allowing reactions to proceed more quickly.

**Hint:** Activation energy is the energy required to start a reaction, and enzymes help reduce this energy barrier.

### Step 3: Review the other statements
Although the question does not provide the other statements, we can infer that we need to check if they also correctly describe enzymes or if any of them contain inaccuracies.

**Hint:** Look for common misconceptions about enzymes, such as their permanence in reactions or their effect on equilibrium.

### Step 4: Identify the incorrect statement
From the video transcript, it is indicated that the first statement is incorrect because it mentions lowering the energy of the product rather than the activation energy. This clarification is crucial since enzymes do not change the energy of the products but rather lower the activation energy.

**Hint:** Focus on the distinction between activation energy and the energy of products when evaluating statements about enzyme functions.

### Step 5: Conclude the answer
After analyzing the statements, we conclude that the first statement is incorrect. Therefore, the answer to the question is that the statement claiming enzymes lower the energy of activation of the reaction is false.

**Final Answer:** The incorrect statement about enzymes is that they lower the energy of the activation of the reaction.
