To determine which metabolic pathway does not occur within the mitochondria, let's analyze the options provided:

1. **Beta-Oxidation of Fatty Acids**: This process takes place in the mitochondria as fatty acids are broken down into acetyl-CoA units for energy production.

2. **Krebs Cycle**: Also known as the citric acid cycle, this metabolic pathway occurs in the mitochondrial matrix, where acetyl-CoA is oxidized.

3. **Glycolysis**: This metabolic pathway takes place in the cytoplasm of the cell, where glucose is broken down into pyruvate, and is therefore the only option that does not occur in the mitochondria.

4. **Electron Transport Chain**: This process occurs across the inner mitochondrial membrane, where electrons are transferred through various complexes to produce ATP.

### Final Answer
**Glycolysis** (Option C) is the process that does not occur within the mitochondria.
