Question

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

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

Answer 1

The correct option is D Mitochondria

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