Answer:

Completely oxidize an acetyl group to carbon dioxide.

Explanation:

The net effect of TCA cycle is the oxidation of acetyl group so as to liberate carbon dioxide (CO₂). This oxidation of acetyl group is coupled to the reduction of hydrogen carriers like NAD⁺ and FAD so as to produce NADH + H⁺ and FADH₂ respectively. During TCA cycle, the acetyl CoA which is formed from pyruvate in PDH complex, transfers it's acetyl group to oxaloacetate which is a 4 carbon compound. As a result of this transfer, a 6 carbon compound known as citrate is formed. This citrate is then passed through a series of reactions during which it is broken down so as to regenerate oxaloacetate back. During these reactions, some very high energy molecules like NADH, ATP and FADH₂ are also produced.

The net effect of the eight steps of the citric acid cycle is to completely oxidize an acetyl group to carbon dioxide.

  • Cellular respiration has three main stages: glycolysis, the Krebs cycle (also called the citric acid cycle) and oxidative phosphorylation.

  • The Krebs cycle releases energy through the oxidation of the acetyl group in acetate derived from foods (i.e., carbohydrates, fats, and proteins), producing carbon dioxide (CO2) as a byproduct of these reactions.

  • Glycolysis occurs in the cytoplasm, while the Krebs cycle and oxidative phosphorylation occur in the mitochondria.

In conclusion, the net effect of the eight steps of the citric acid cycle is to completely oxidize an acetyl group to carbon dioxide.
