Quizplus · Accepted Answer

In bacteria, there are no membrane-bound organelles, and all metabolic pathways occur in the cytoplasm. Therefore, the TCA cycle (also known as the Krebs cycle or the citric acid cycle) is located in the cytoplasm of bacteria. In eukaryotes, the TCA cycle occurs in the mitochondrial matrix, which is a compartment within the mitochondria that is surrounded by the inner mitochondrial membrane. The outer mitochondrial membrane is not involved in the TCA cycle. Therefore, choice A is the correct answer.

The TCA Cycle Is Located in the ______________ of Bacteria,and
