Classification of plant mineral nutrients according to biochemical function

Mineral nutrient	Functions
A.)  Silicon(Si)	1.)    Constituent of alcohol dehydrogenase, glutamic dehydrogenase, carbonic anhydrase, etc
B.)  Manganese(Mn)	2.)    Component of sugar phosphates, nucleic acids, nucleotides, coenzymes, phospholipids, phytic acid, etc. Has a key role in reactions that involve ATP
C.)  Zinc(Zn)	3.)    Contributes to cell wall mechanical properties, including rigidity and elasticity.
D.)  Phosphorous(P)	4.)    Component of ascorbic acid oxidase, tyrosinase, monoamine oxidase, uricase, cytochrome oxidase, phenolase, laccase, and plastocyanin.
E.)   Copper(Cu)	5.)    Required for activity of some dehydrogenases, decarboxylases, kinases, oxidases, and peroxidases. Involved with other cation-activated enzymes and photosynthetic O2 evolution

#Unit 1. Molecules and their Interaction Relevant to Biology

If the 16-carbon saturated fatty acid palmitate is oxidized completely to carbon dioxide and water (via the B-oxidation pathway and the citric acid cycle), and all of the energy-conserving products are used to drive ATP synthesis in the mitochondrion, the net yield of ATP per molecule of palmitate is:
