a
water and carbon dioxide and ATP
b
water and carbon dioxide
c
water, oxygen and ATP
d
glucose, oxygen and light
b. water and carbon dioxide
The products of aerobic cellular respiration are water, carbon dioxide, and ATP. Therefore, the correct answer would be option b: water and carbon dioxide.
The correct answer is option (b) water and carbon dioxide. To understand why, let's break down what happens in aerobic cellular respiration.
Aerobic cellular respiration is the process in which cells use oxygen to break down glucose and produce energy in the form of ATP (adenosine triphosphate). This process occurs in the mitochondria of cells.
During aerobic cellular respiration, glucose (a sugar molecule) is broken down in a series of steps. Oxygen from the air we breathe is involved in these reactions, which occur in the presence of enzymes.
The overall chemical equation for aerobic cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
In this equation, glucose (C6H12O6) is combined with oxygen (O2), which results in the production of carbon dioxide (6CO2), water (6H2O), and ATP. ATP is the energy currency of cells.
So, the products of aerobic cellular respiration are carbon dioxide and water (option b). ATP is also produced but is not listed as a separate product in the given options.
