Which of the following is a reactant of cellular respiration? (1 point)
Responses
energy.
energy.
oxygen.
oxygen.
carbon dioxide.
carbon dioxide.
water.
oxygen.
The reactant of cellular respiration is oxygen.
To determine which of the options is a reactant of cellular respiration, we need to understand the process of cellular respiration. Cellular respiration is a complex biochemical process that occurs in cells, where organic compounds, usually glucose, are broken down to release energy in the form of ATP (adenosine triphosphate).
During cellular respiration, oxygen is used as a reactant along with glucose (a sugar molecule) to produce carbon dioxide, water, and energy. The energy produced is then utilized for various cellular functions.
Therefore, the reactant of cellular respiration from the given options is oxygen.
