Question

What happens when oxygen gas reacts with ADP and NADP+?

1) Energy carriers are converted into oxygen gas
2) ADP and NADP+ are converted into energy carriers
3) Oxygen gas is converted into ADP and NADP+
4) ADP and NADP+ are converted into oxygen gas

Answer 1

Oxygen gas reacts with ADP and NADP+ to convert them into energy carriers ATP and NADPH, respectively, during cellular respiration.

Step-by-step explanation:

When oxygen gas reacts with ADP and NADP+, neither of them is converted into the other, but rather they are converted into energy carriers in a process known as cellular respiration. Specifically, the reaction mentioned is part of the electron transport chain where oxygen is used to accept electrons, leading to the formation of water. This reaction, catalyzed by the presence of oxygen, allows for the energy released to power the phosphorylation of ADP into ATP, and the reduction of NADP+ to NADPH. Both of these molecules then carry energy to other parts of the cell where it is needed.

In light of the given options, the correct answer would be 2) ADP and NADP+ are converted into energy carriers.
