3.1 Biological elements Flashcards
what elements do carbs, lipids, proteins and nucleic acids contain
Carbohydrates- C H & O
Lipids- C H & O
Proteins- C H O N & S
Nucleic acids - C H O N & P
what do Ca 2+ ions do
necessary for nerve impulse transmission and muscle contraction
what do Na+ ions do
necessary for nerve impulse transmission and kidney function
what do H+ ions do
they are necessary for the catalysis of reactions and pH determination
what do NO3- ions do (nitrate ions)
they are necessary for the supply of nitrogen to plants and for amino acid and protein formation
what do OH- ions do
they are necessary for the catalysis of reactions and pH determination
what are K+ ions necessary for
nerve impulse transmission and stomatal opening
what are NH4+ ions necessary for
the production of nitrate ions by bacteria
what are HCO3- ions necessary for
maintaining blood pH
what are PO43- ions necessary for
cell membrane function and nucleic acid and ATP formation
