C mitochondria

C. mitochondria

The correct answer is C) mitochondria.

To arrive at this answer, we need to understand the process of cellular respiration and the organelles involved.

Cellular respiration is the process by which cells convert oxygen and glucose into ATP (adenosine triphosphate), which is the main energy currency of the cell. It occurs in three main stages: glycolysis, the Krebs cycle, and the electron transport chain.

First, during glycolysis, glucose is partially broken down in the cytoplasm of the cell. This process does not take place within any specific organelle.

Next, the products of glycolysis, along with oxygen, enter the mitochondria, where the Krebs cycle (also known as the citric acid cycle) occurs. The Krebs cycle takes place in the matrix of the mitochondria. During this stage, more chemical reactions occur and more ATP is produced.

Finally, the electron transport chain takes place on the inner membrane of the mitochondria. Here, electrons are passed along a series of proteins, creating a flow of energy. This energy is used to generate ATP.

Overall, the majority of ATP in cellular respiration is produced in the mitochondria, making option C the correct answer.
