mineral ions Flashcards
hydrogen
plants - chemiosmosis, ATP synthesis - photosynthesis and respiration
animals - pH (blood) ATP synthesis, chemisomosis - respiration
high concentration of H+ = low pH (acidic)
H+ ions interact with H-bonds and ionic bonds in tertiary structure of proteins, which can cause them to denature
hydrogen carbonate
plants - source of CO2 for submerged plants
animals - CO2 in blood plasma
what are inorganic ions
Inorganic ions are charged particles that are not part of a larger organic molecule
Inorganic ions occur in solution in the cytoplasm and body fluids of organisms, some in high concentrations and others in very low concentrations
nitrite, nitrate, ammonium
nitrogen cycle
proteins
nucleic acids
sodium
neural transmission
co-transport with glucose and amino acid in intestine and kidneys
magnesium
component of chlorophyll
sulphate
proteins - 2/20 aa
potassium
stomata - opening and closing
neural transmission
calcium
synapses and muscle contraction
iron
Fe 2+ bonds to porphyrin ring to form haem group in haemoglobin
haem group has binding site to transport 1 molecule of O2 around the body in the bloodstream
4 haem groups per haemoglobin molecule
what are inorganic ions and where are they found in the body
ions that do not contain carbon atoms
found in cytoplasm and extracellular fluid
may be in high or very low concentrations
phosphate
phospholipids and nucleic acids
component of DNA, ATP, NADP, cAMP
