Which of the following organelles is responsible for lipid metabolism?
Correct answer: B. SER
- A. Vacuole
- B. SER
- C. Mitochondria
- D. Chloroplasts
- E. RER
Explanation
Mitochondria is the powerhouse of the cell that provides energy in the form of ATP. Rough Endoplasmic Reticulum ( RER ) has ribosomes on its surface and is thus involved in protein synthesis. Chloroplast is the center for the phenomena of photosynthesis thus converting light energy to chemical energy for the cell. Vacuoles perform a number of different functions including storage of food, containing waste products etc. Smooth Endoplasmic Reticulum ( SER ) have a smooth surface because of the absence of ribosomes and is involved in lipid metabolism and transport in the cell.
