Explanation:
The final acceptor molecule in the electron transport chain is oxygen. When oxygen accepts hydrogen ions, it forms water. This is why water is released as a byproduct of cellular (aerobic) respiration
Answer:
Option B, Transcription that originates at the core promoter and +1 site
Explanation:
In basal transcription process a special class of transcription factors which are nothing but the protein that binds to specific sites on DNA (which are also known as promoter sites) with an objective of activating transcription of genetic information from DNA to RNA , specifically messenger RNA. The transcription initiation requires association at promoter site(or regions of DNA that are found in the upstream of the coding region of a gene) along with a σ sub unit
Hence, option B is correct
