Why is the production of adenosine triphosphate by chemiosmosis in mitochondria called oxidative phosphorylation?
ABecause oxygen is involved in the process
BBecause oxides of carbon are made in it
CBecause it oxidizes the inner membrane
DBecause it removes oxygen from water
Answer & Solution
Correct answer: A. Because oxygen is involved in the process
1. Oxidative phosphorylation is defined as the production of adenosine triphosphate using chemiosmosis and oxygen.
2. The name records the involvement of oxygen in the process.
3. Water is a product of the pathway rather than something oxygen is stripped from.
4. Carbon dioxide is released in earlier stages, so making oxides of carbon is not what gives this step its name.
