The end product of glycolysis is

Options

A. pyruvic acid
B. glucose
C. ethyl alcohol
D. `CO_(2)`

Explanation

**Step-by-Step Solution:**

1. **Understanding Glycolysis**: Glycolysis is a metabolic pathway that involves the breakdown of glucose, which is a six-carbon sugar, into smaller molecules. This process is crucial for cellular respiration and energy production in cells.

2. **Identifying the Raw Material**: The raw material for glycolysis is glucose. During glycolysis, glucose undergoes a series of enzymatic reactions.

3. **The Process of Breakdown**: Through these reactions, glucose is converted into two molecules of pyruvate (or pyruvic acid). Each pyruvate molecule consists of three carbon atoms.

4. **Location of Glycolysis**: Glycolysis occurs in the cytoplasm of the cell, making it a key process in both aerobic and anaerobic respiration.

5. **Final Product**: The end product of glycolysis is pyruvate (or pyruvic acid). This is the molecule that results from the breakdown of one glucose molecule.

6. **Conclusion**: Therefore, the correct answer to the question "The end product of glycolysis is" is **pyruvic acid**.
