Carbon skeleton produced during respiration is used as precursor for biosynthesis of other molecules in the cell thus respiration is:

Options

A. Catabolic process
B. Anabolic process
C. Amphibolic process
D. Developmental process

Answer

To solve the question, we need to analyze the role of respiration in the context of cellular metabolism and the biosynthesis of other molecules. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Respiration**:
- Respiration is a metabolic process that breaks down organic molecules (like glucose) to release energy. This process involves a series of biochemical reactions that convert glucose into ATP, the energy currency of the cell.

**Hint**: Think about the primary function of respiration in cells and what it accomplishes.

2. **Carbon Skeleton Production**:
- During respiration, particularly in the Krebs cycle (citric acid cycle), carbon skeletons are produced. These carbon skeletons can serve as precursors for the synthesis of various biomolecules.

**Hint**: Recall the Krebs cycle and its role in producing intermediates that can be used for biosynthesis.

3. **Biosynthesis of Molecules**:
- The carbon skeletons produced during respiration can be used to synthesize other important molecules, such as amino acids, nucleotides, and other metabolic intermediates. This process of synthesizing new molecules from smaller units is known as anabolism.

**Hint**: Differentiate between anabolic processes (building up) and catabolic processes (breaking down).

4. **Identifying the Type of Process**:
- The question asks us to identify what type of process respiration is when it involves the production of carbon skeletons that are used for biosynthesis. Since respiration provides the building blocks for synthesizing other molecules, it indicates an anabolic process.

**Hint**: Consider the definitions of catabolic (breaking down) and anabolic (building up) processes.

5. **Evaluating the Options**:
- **Catabolic Process**: Incorrect, as this refers to breaking down molecules.
- **Anabolic Process**: Correct, as it refers to the synthesis of new molecules using the carbon skeletons produced during respiration.
- **Amphibolic Process**: Incorrect, as this refers to pathways that involve both catabolic and anabolic reactions.
- **Developmental Process**: Incorrect, as this is not a term commonly used in the context of cellular respiration.

**Hint**: Eliminate options based on their definitions and how they relate to the process described in the question.

### Final Answer:
The correct answer is **Option 2: Anabolic Process**.
