Explanation / Answer
1. Rough endoplasmic reticulum (RER) is the cellular organelle that contains ribosomes on the surface of the ER. The protein synthesis takes place on rough endoplasmic reticulum and the proteins synthesized are destined either towards plasma membrane and /or secreted out of the cell. Option b is correct.
2. Oxygen is known as "Elixir of life". This is because oxygen is an important molecules required for sustaining life and almost all metabolic processes require oxygen. Option d is correct.
3. oxygen is the final electron acceptor in aerobic respiration. In anaerobic respiration, the final electron acceptors are sulfate, nitrate or hydrogen etc. Water is produced as byproduct during aerobic respiration. Option d is correct.
4. The protein synthesis process is called as translation in which the RNA is read by the cell and protein is made. Option c is correct.
5. The RNA is synthesized from DNA using it as template and this process is known as transcription. Option b is correct.
