Convert the following:

A. ADP to ATP
B. ATP to ADP
C. [tex]NADP ^{+}[/tex] to [tex]NADPH[/tex]
D. [tex]CO_2[/tex] and [tex]H_2O[/tex] to [tex]C_6H_{12}O_6[/tex] and [tex]O_2[/tex]



Answer :

Sure, let's break down these biological processes in detail:

1. ADP to ATP (Adenosine Diphosphate to Adenosine Triphosphate):
- This reaction involves the addition of a phosphate group to ADP to form ATP. It is a critical process for energy storage in cells.
- The process is as follows:
[tex]\[ \text{ADP + P}_i + \text{Energy} \rightarrow \text{ATP} \][/tex]
- Here, [tex]\( \text{P}_i \)[/tex] represents inorganic phosphate. This reaction typically occurs during cellular respiration or photosynthesis, where energy from food or light is used to form ATP.

2. ATP to ADP:
- This is the reverse of the previous reaction and involves the release of energy.
- The process is as follows:
[tex]\[ \text{ATP} \rightarrow \text{ADP + P}_i + \text{Energy} \][/tex]
- When ATP is hydrolyzed (a phosphate group is removed), energy is released for cellular functions.

3. NADP[tex]\(^+\)[/tex] to NADPH:
- This reaction involves the reduction of NADP[tex]\(^+\)[/tex] to NADPH through the gain of electrons.
- The process is as follows:
[tex]\[ \text{NADP}^+ + 2e^- + 2H^+ \rightarrow \text{NADPH} + H^+ \][/tex]
- NADPH is an electron carrier used in various biochemical reactions, including the Calvin cycle in photosynthesis.

4. CO[tex]\(_2\)[/tex] and H[tex]\(_2\)[/tex]O to C[tex]\(_6\)[/tex]H[tex]\(_{12}\)[/tex]O[tex]\(_6\)[/tex] and O[tex]\(_2\)[/tex] (Photosynthesis):
- This is the process where plants convert carbon dioxide and water into glucose and oxygen using sunlight.
- The overall balanced chemical equation for photosynthesis is:
[tex]\[ 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \][/tex]
- This process occurs in the chloroplasts of plant cells with the help of the pigment chlorophyll.

In summary:
- The conversion of ADP to ATP is essential for storing energy.
- The conversion of ATP to ADP releases energy for cellular processes.
- The reduction of NADP[tex]\(^+\)[/tex] to NADPH is crucial for electron transfer in biochemical reactions.
- Photosynthesis converts CO[tex]\(_2\)[/tex] and H[tex]\(_2\)[/tex]O into glucose and O[tex]\(_2\)[/tex], providing energy and oxygen for life on Earth.
