Name four parts of cell respiration.

Explanation

**Step-by-Step Solution:**

1. **Understanding Respiration**: Respiration is a biochemical process where complex organic compounds are broken down to release energy. This process occurs in cells and involves several stages.

2. **Identifying the Parts of Cellular Respiration**: The four main parts of cellular respiration are:
- **Glycolysis**: This is the first step where glucose is broken down into pyruvic acid, resulting in a net gain of 2 ATP molecules.
- **Oxidative Decarboxylation**: In this step, pyruvic acid is converted into acetyl-CoA. This step acts as a link between glycolysis and the Krebs cycle.
- **Krebs Cycle (Citric Acid Cycle)**: Acetyl-CoA enters this cycle, where it undergoes a series of reactions to produce ATP and electron carriers.
