we know automatically that glucose and pyruvate are wrong answers due to the fact that glucose is sugar and that pyruvate is a type of acid. this just leaves us with ADP and ATP now ADP and ATP are very close answers, since ADP is what makes ATP, but an electron transport change usually involves the transfer of electrons well if we look at their chemical formulas, we can see that ATP has more 1 more oxygen than ADP, and this kind of chain usually adds additional oxygen which gives us ATP as our answer.
Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon from the atmosphere
Explanation:
This is the role of the reactions in the carbon cycle.
