Question

In which of these cell organelle does the electron transfer chain reaction occur?

• A. Golgi body
• B. Ribosome
• C. Cytoplasm
• D. Mitochondria

Answer 1

The correct option is D Mitochondria

Golgi body is the cell organelle associated with the sorting and packaging of proteins. Ribosomes on the other hand synthesise proteins. Cytoplasm is the site where the process of glycolysis occurs. The product of glycolysis that is pyruvic acid is converted into acetyl coA molecules and enter mitochondria for tricarboxylic acid cycle. Molecules of $NAD{H}_2$ and $FAD{H}_2$ formed during the above processes participate in electron transfer chain reaction that occurs in mitochondria.
