The six-carbon molecule that forms when acetyl CoA joins its two carbons to a four-carbon molecule during the Krebs cycle is citrate.
The Kreb's cycle also known as the tricarboxylic acid cycle is the cycle that produces the reducing equivalents NADH and FADH₂ from the acetyl CoA molecules obtained from the glycolytic cycle.
The reducing equivalents NADH and FADH₂ enter the electron transport chain and are used to drive proton pumping resulting in the synthesis of ATP molecules.
In the first step of the Kreb's cycle, the molecule acetyl CoA is joined to oxaloacetate to produce citrate.

The six-carbon molecule that forms when acetyl coA joins its 2 carbon to a 4 carbon molecule during the Krebs cycle is citrate.
Krebs cycle is a series of enzymatic reactions that occurs in all aerobic organisms. It involves the oxidative metabolism of acetyl units, and serves as the main source of cellular energy.
The Krebs cycle starts with the products of glycolysis, which are two three-carbon molecules known as pyruvate. This molecule is acidic, which is why the Krebs cycle is also called the tricarboxylic acid cycle (TCA).
Citrate, a six carbon molecule, is the first molecule created after acetyl CoA is added. This is why the Krebs cycle is also known as the citric acid cycle.
