Answer:
Photosynthesis
Explanation:
Atmospheric carbon dioxide is converted to glucose during the Calvin-Benson cycle. This requires the overall reduction of CO2, using the electrons available from the oxidation of NADPH. Thus the dark reactions represent a redox pathway. NADPH is oxidized to NADP+ and CO2 is reduced to glucose.
Valine is a hydrophobic amino acid used for biosynthesis of proteins. It is essential in humans, meaning the body cannot synthesize it and it must be obtained from the diet.
Glutamic is a hydrophilic amino acid used by almost all living beings in the biosynthesis of proteins. It is non-essential in humans and the body can synthesize it.
