To determine the chemical equation that shows the relationship between ADP (Adenosine Diphosphate) and ATP (Adenosine Triphosphate), let's analyze each given option carefully:
A. [tex]\( ATP \rightarrow ADP + H^+ \)[/tex]
- This option indicates that ATP breaks down into ADP and a proton (H^+).
B. [tex]\( ATP \rightarrow ADP + NADP^+ \)[/tex]
- This option suggests that ATP breaks down into ADP and NADP^+ (Nicotinamide Adenine Dinucleotide Phosphate).
C. [tex]\( ATP \rightarrow ADP + P \)[/tex]
- This option states that ATP breaks down into ADP and a phosphate group (P). This is the commonly known reaction where ATP loses one phosphate group to release energy, while turning into ADP in the process.
D. [tex]\( ATP - ADP + NADPH \)[/tex]
- This option doesn't represent a clear and standard chemical equation, and it appears to be incorrect in its structure and format.
The chemical equation that properly illustrates the relationship between ATP and ADP is the process where ATP releases a phosphate group to form ADP. This process releases energy required for various cellular activities.
Thus, the correct option is:
C. [tex]\( ATP \rightarrow ADP + P \)[/tex]
Therefore, the chemical equation representing the relationship between ADP and ATP is:
C. [tex]\( ATP \rightarrow ADP + P \)[/tex]
