Identify the wrong statements
(a) The substrate binds to active site of enzyme and not fitting into active site
(b) The binding of substrate induces the enzyme to alter its shape
(c ) Chemical bonds of substrate break down not to form now enzyme product complex
(d) The enzyme releases the products of the reaction and run through catalytic cycle once again

Options

A. a,c
B. b.d
C. b,c
D. a,d

Answer

To identify the wrong statements among the given options, we will analyze each statement based on our understanding of enzyme-substrate interactions.

### Step-by-Step Solution:

1. **Analyze Statement (a)**: "The substrate binds to the active site of the enzyme and not fitting into the active site."
- This statement is incorrect. The substrate must fit into the active site of the enzyme. Enzymes are specific, and the shape of the substrate is complementary to the shape of the active site, allowing for a proper fit. Therefore, this statement is wrong.

2. **Analyze Statement (b)**: "The binding of substrate induces the enzyme to alter its shape."
- This statement is correct. When a substrate binds to the active site of an enzyme, it often induces a conformational change in the enzyme. This change helps the enzyme to better accommodate the substrate, leading to the formation of the enzyme-substrate complex.

3. **Analyze Statement (c)**: "Chemical bonds of substrate break down not to form now enzyme product complex."
- This statement is incorrect. The correct process involves the breaking of chemical bonds in the substrate to form products, leading to the formation of an enzyme-product complex. The statement misrepresents the process by suggesting that the enzyme-product complex is not formed, which is wrong.

4. **Analyze Statement (d)**: "The enzyme releases the products of the reaction and runs through catalytic cycle once again."
- This statement is correct. After the reaction, the enzyme releases the products and is free to bind with another substrate molecule, thus continuing the catalytic cycle.

### Conclusion:
The wrong statements are (a) and (c).

### Final Answer:
The wrong statements are (a) and (c).
