Scientists used radioactive hydrogen to make water. They grew plants using the radioactive water. What happened to the radioactive hydrogen during cellular respiration
Can I just get answers for the question from connexus for question one through nine
Don’t worry, I’m gonna come back with the answers for the full practice
where is it??
During cellular respiration, the radioactive hydrogen, represented by the isotope known as tritium (^3H), would follow the same pathway as regular hydrogen. Let's break down the process of cellular respiration to understand what happens.
Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy (ATP). It occurs in three main stages: glycolysis, the Krebs cycle, and the electron transport chain.
In glycolysis, which takes place in the cytoplasm, glucose is broken down into two molecules of pyruvate. During this stage, some hydrogen atoms are released and temporarily stored in the form of high-energy electron carriers – NADH and FADH2.
Next, pyruvate enters the mitochondria and undergoes further breakdown in the Krebs cycle. Here, more hydrogen atoms are released and captured by electron carriers. These carriers, mainly NADH and FADH2, will proceed to the final stage: the electron transport chain.
In the electron transport chain, located on the inner membrane of the mitochondria, the high-energy electrons from NADH and FADH2 are transported through a series of protein complexes. Finally, these electrons combine with oxygen and hydrogen ions (H+) to form water (H2O) as a byproduct.
So, in the process of cellular respiration, the radioactive hydrogen (^3H) that was present in the initial water used to grow the plants would be incorporated into the metabolic water produced during cellular respiration. This means that the radioactive hydrogen would eventually become part of the water molecules (H2O) formed as a result of the entire process.
It's important to note that this explanation assumes the radioactive hydrogen is safely incorporated into cellular processes. Radioactive materials can have biological effects, and any experiments involving radioactive substances should be conducted with proper safety precautions and under controlled conditions.
