A three carbon sugar of Glycolysis is

Options

A. 3 Phosphoglyceric acid
B. Pyruvic acid
C. Glyceraldehyde 3-phosphate
D. 1-3 disphosphoglyceric acid

Answer

**Step-by-Step Solution:**

1. **Understanding Glycolysis**: Glycolysis is a metabolic pathway that breaks down glucose (C6H12O6) into smaller molecules. It occurs in the cytoplasm of cells and is the first step in cellular respiration.

2. **Identifying the Starting Material**: The starting material for glycolysis is glucose, which is a six-carbon sugar. During glycolysis, glucose is converted into two molecules of a three-carbon compound.

3. **Recognizing the Three-Carbon Product**: The three-carbon sugar produced during glycolysis is known as pyruvic acid (or pyruvate). This occurs after a series of enzymatic reactions that involve the phosphorylation and cleavage of glucose.

4. **Conclusion**: Therefore, the three-carbon sugar of glycolysis is pyruvic acid.

**Final Answer**: The three-carbon sugar of glycolysis is pyruvic acid.
