Name the first chemical produced in Krebs' cycle.

Explanation

### Step-by-Step Solution:

1. **Understanding the Krebs Cycle**: The Krebs cycle, also known as the Tricarboxylic Acid (TCA) cycle, is a series of chemical reactions used by all aerobic organisms to generate energy.

2. **Starting Molecules**: The cycle begins with the condensation of two key molecules: Acetyl-CoA and Oxaloacetate.

3. **Formation of the First Product**: When Acetyl-CoA combines with Oxaloacetate, the first chemical compound produced is Citric Acid (also known as Citrate).
