Answer:
The reactions of glycolysis occur in the cell's cytoplasm; the reactions of the citric acid cycle occur in the mitochondria.
Step-by-step explanation:
Explanations of some terms
Glycolysis
Glycolysis takes place in the cytosol of the cell's cytoplasm. Glycolysis starts when glucose diffuses into a cell through the plasma membrane down its concentration gradient. Glycolysis is a metabolic pathway present in all organisms: from yeast to mammals that involves the oxidation of glucose molecules, the single most important organic fuel in plants, and animals to pyruvate with the generation of ATP (Adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide + hydrogen)
Citric acid cycle
Citric acid cycle also known as the Krebs cycle plays a major role in the process of energy production and biosynthesis as it oxidizes glucose derivatives, fatty acids and amino acids to carbon dioxide.
