instructions
decarboxylation of pyruvate to acetyl coa
citric acid cycle
electron transport chain
glycolysis

Explanation:

• Glycolysis is the process that converts glucose into pyruvate and produces a small amount of ATP. In the diagram, the process labeled A produces ATP and pyruvate, which matches glycolysis.
• The decarboxylation of pyruvate to Acetyl - CoA is the step that occurs after glycolysis and before the citric acid cycle. The process labeled B takes pyruvate and is the entry step into the mitochondrial matrix (where the citric acid cycle occurs), so it is the decarboxylation of pyruvate to Acetyl - CoA.
• The citric acid cycle (also known as the Krebs cycle) occurs in the mitochondrial matrix. The green cycle labeled C in the mitochondrial matrix is the citric acid cycle.
• The electron transport chain is located on the inner mitochondrial membrane. The structure labeled D (on the inner mitochondrial membrane folds - cristae) is the electron transport chain.

Answer:

A. glycolysis, B. decarboxylation of pyruvate to Acetyl CoA, C. citric acid cycle, D. electron transport chain.
