Question

Which of the following cell organelles is responsible for extracting energy from carbohydrates to form ATP?

• A. Lysosome
• B. Ribosome
• C. Chloroplast
• D. Mitochondrion

Answer 1

The correct option is D

Mitochondrion

The correct option is D.

The explanation for the correct option:

1. Complete oxidation of carbohydrates takes place in mitochondria during aerobic respiration.
2. Krebs cycle and electron transport chain occur in mitochondria and ATP is produced.
3. Therefore, mitochondria are known as the powerhouse of a cell.

The explanation for the incorrect options:

Option A:

1. Lysosomes are membrane-bound organelles, and the lumen, which includes hydrolytic enzymes and other cellular waste, is located within the membrane.

Option B:

1. Ribosomes are found in both prokaryotic and eukaryotic cells, which are specialized cell organelles.
2. Ribosomes are required for the formation of proteins in every live cell.

Option C:

1. All green plants and algae include chloroplasts.
2. These are found in the plant's mesophyll cells, which are found in the leaves.
3. Animal cells do not have this cell organelle.

Final Answer: Mitochondrion cell organelles are responsible for extracting energy from carbohydrates to form ATP.
