Scientists used radioactive hydrogen to make water. They grew plants using the radioactive water. What happened to the radioactive hydrogen during cellular respiration?(1 point)

Question

Responses

It was recycled into hydrogen gas.
It was recycled into hydrogen gas.

It was recycled into glucose.
It was recycled into glucose.

It was recycled into protein.
It was recycled into protein.

It was recycled into water.

Answer 1

During cellular respiration, the radioactive hydrogen that was incorporated into water (H₂O) during plant growth would be broken down and eventually utilized in the process of respiration. Specifically, hydrogen is involved in the production of water during cellular respiration when glucose is broken down. Therefore, the most accurate response would be:

It was recycled into water.
