The Citric Acid Cycle Is a Critical Sequence of Reactions

The citric acid cycle is a critical sequence of reactions for energy production, which take place in the matrix of the mitochondria.The reaction cycle requires materials from the cytosol to be converted into acetyl CoA, which represents the starting point of a new cycle.Which of the following statements about acetyl CoA is TRUE?

A) Amino acids can be converted into acetyl CoA.
B) Pyruvate is converted into acetyl CoA in the cytosol.
C) Triacylglycerol molecules are transported into the mitochondrial matrix and cleaved by lipases to produce acetyl CoA.
D) Oxaloacetate is converted directly into acetyl CoA to feed the citric acid cycle.
