Which organic compound acts as link between glycolysis and Krebs' cycle ?

Explanation

### Step-by-Step Solution:

1. **Understanding Glycolysis**: Glycolysis is the metabolic process that breaks down glucose (a sugar) into pyruvic acid. This process occurs in the cytoplasm of the cell and is the first step in cellular respiration.

2. **Formation of Pyruvic Acid**: During glycolysis, one molecule of glucose (6 carbon atoms) is converted into two molecules of pyruvic acid (3 carbon atoms each). This process involves a series of enzymatic reactions and results in a small yield of ATP and NADH.

3. **Link Reaction**: The pyruvic acid produced from glycolysis cannot directly enter the Krebs cycle. Instead, it undergoes a conversion process known as the link reaction. In this reaction, each pyruvic acid molecule is decarboxylated (loses a carbon dioxide molecule) and is transformed into acetyl-CoA.
