F1 particles are present in:
Correct answer: B. Mitochondria
- A. Chloroplast
- B. Mitochondria
- C. Ribosome
- D. All of these
Explanation
F1 particles, also known as the F1 portion of ATP synthase, are found in the inner membrane of mitochondria. They play a vital role in the production of ATP during cellular respiration by facilitating the conversion of ADP to ATP. Chloroplasts, involved in photosynthesis, contain ATP synthase but in a different form associated with the thylakoid membranes. Ribosomes are the site of protein synthesis and are not related to ATP production, hence do not contain F1 particles. The option 'All of these' is incorrect as F1 particles are specific to mitochondria.
