Glycolysis is also called

Options

A. EMP Pathway
B. amphibolic pathway
C. triosis
D. both (1) and (3)

Answer

**Step-by-Step Solution:**

1. **Understanding Glycolysis**: Glycolysis is a metabolic process that breaks down glucose (a 6-carbon sugar) into pyruvic acid (a 3-carbon compound). This process occurs in the cytoplasm of both prokaryotic and eukaryotic cells.

2. **Identifying Alternative Names**: Glycolysis is known by different names based on its discovery and characteristics. It is primarily referred to as the EMP pathway, named after the scientists who discovered it: Embden, Meyerhof, and Parnas.

3. **Exploring Other Terms**: The term "amphibolic pathway" refers to metabolic pathways that involve both anabolic (building up) and catabolic (breaking down) processes. However, this term is not specifically used for glycolysis but rather for respiration in general.

4. **Considering the Term "Triosis"**: Since glycolysis converts a 6-carbon glucose molecule into two 3-carbon pyruvic acid molecules, it can also be referred to as "triosis," which indicates the presence of 3-carbon compounds.

5. **Evaluating the Options**:
- Option 1: EMP pathway - Correct, as glycolysis is known by this name.
- Option 2: Amphibolic pathway - Incorrect, as this term refers to respiration, not glycolysis.
- Option 3: Triosis - Correct, as glycolysis involves the formation of 3-carbon compounds.
- Option 4: Both 1 and 3 - Correct, as both EMP pathway and Triosis are valid names for glycolysis.

6. **Conclusion**: The correct answer to the question "Glycolysis is also called" is option 4: both 1 (EMP pathway) and 3 (Triosis).
