Which of the following statement is not correct ?

Options

A. There is no uncatalysed metabolic conversion in living systems
B. The living state is a equilibrium steady state to be able to perform work
C. The living state and metabolism are synonymous
D. The calalysts which hasten the rate of a given metabolic conversation are also proteins and these proteins with catalytic power are named enzymes

Answer

To solve the question of which statement is not correct, we will evaluate each of the provided statements one by one.

### Step 1: Analyze the First Statement
**Statement:** "There is no uncatalyzed metabolic conversion in living systems."
- **Analysis:** This statement is true. In living organisms, all metabolic reactions are catalyzed by enzymes, which are proteins that speed up chemical reactions.

### Step 2: Analyze the Second Statement
**Statement:** "The living state is an equilibrium steady state to be able to perform work."
- **Analysis:** This statement is false. Living organisms exist in a non-equilibrium steady state, which allows them to perform work. At equilibrium, no work can be done.

### Step 3: Analyze the Third Statement
**Statement:** "The living state and metabolism are synonymous."
- **Analysis:** This statement is true. Metabolism encompasses all biochemical processes that maintain the living state, providing the energy necessary for life.

### Step 4: Analyze the Fourth Statement
**Statement:** "The catalyst which hastens the rate of given metabolic conversions are also proteins and these proteins with catalytic power are named enzymes."
- **Analysis:** This statement is true. Enzymes are indeed proteins that act as catalysts in metabolic reactions, increasing the rate of these reactions.

### Conclusion
After analyzing all the statements, the only incorrect statement is the second one: "The living state is an equilibrium steady state to be able to perform work." Therefore, the answer is option 2.
