Miko · Answer 1

The correct answer is d. to remove carbon dioxide from glucose molecules

Explanation:

The Krebs cycle occurs in the matrix of the eukaryotic cell mitrochondria and in the cytoplasm in bacteria. In this process, molecular oxygen is required to oxidize substrates and remove carbon dioxide molecules.

This is also called the cycle: citric acid or tricarboxylic acid cycle (citric acid is the first product of the cycle being substrates, molecules of 3 carbon atoms). This process turns out to be the final stage of all catabolic pathways, where the decomposition of organic molecules for energy is performed.
