The function of the citric acid cycle is to transfer the acetyl group gained from glycolysis to molecules of pyruvate. hydrolyze glucose in the presence of oxygen to obtain two pyruvate molecules. remove hydrogen atoms from organic molecules and transfer them to coenzymes. produce water. produce carbon dioxide to balance the oxygen requirement for cellular respiration.

The function of the citric acid cycle is to produce carbon dioxide to balance the oxygen requirement for cellular respiration.

Explanation:

In the citric acid cycle, pyruvate is first decarboxylated, leading  to the production of CO₂, NADH, and the energy-rich substance  acetyl-CoA. The acetyl group of acetyl-CoA then combines with  the four-carbon compound oxaloacetate, forming the six-carbon  compound citric acid. A series of reactions follow, and two  additional CO₂ molecules, three more NADH, and one FADH are  formed. Ultimately, oxaloacetate is regenerated to return as an  acetyl acceptor, thus completing the cycle .

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.  

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
