Which of the following is used to build and repair body tissues

Options

A. Cane sugar
B. fructose
C. Protein
D. Glucose

Explanation

To determine which biomolecule is used to build and repair body tissues, we can follow these steps:

### Step 1: Identify the options
First, we need to identify the options provided in the question. Typically, the options could include carbohydrates, proteins, lipids, and nucleic acids.

### Step 2: Understand the role of proteins
Proteins are essential biomolecules that play a crucial role in the body. They are made up of amino acids and are involved in various functions, including:

- Building and repairing body tissues
- Serving as enzymes to catalyze biochemical reactions
- Acting as hormones and antibodies

### Step 3: Analyze the function of other biomolecules
While proteins are primarily responsible for building and repairing tissues, we can briefly analyze the roles of other biomolecules:

- **Carbohydrates**: Mainly serve as a source of energy.
- **Lipids**: Primarily function as energy storage and structural components of cell membranes.
- **Nucleic Acids**: Involved in the storage and transmission of genetic information.

### Step 4: Conclude the answer
Based on the analysis, we can conclude that proteins are the biomolecules specifically used to build and repair body tissues.

### Final Answer:
**Proteins** are used to build and repair body tissues.
