What’s the role of oxygen in cellular respiration? asap

The letter A is the right answer.

Explanation:

Cellular respiration occurs in the presence of oxygen. This element is essential in the cellular respiration process, since it is responsible for accepting electrons and keeping the electron transport chain functioning.

Cellular respiration occurs after glycolysis, where pyruvate is formed along with 2 molecules of ATP. In the presence of oxygen, pyruvate is oxidized to a two-carbon compound that will react with co-enzyme-A and form NADH and CO2. This process will start the electron transport chain that will result in a protonic gradient that will transform ADP into ATP. The electron receptor in this process is oxygen, which will later be combined with hydrogen molecules to form water.

chemical because it warmed up which involves temperature and it bubbled which includes changing

mark me brainiest

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
