are atoms or molecules with an electric charge, containing no carbon

Question 2

What are cations?

Answer 2

positively charged ions

Question 3

What are anions?

Answer 3

negatively charged ions

Question 4

Where do Inorganic ions occur?

Answer 4

in solution in the cytoplasm and body

fluids of organisms, some in high concentrations and others in very low concentrations

Question 5

role of h + ions

Answer 5

determine the pH of bodily fluids. The higher the concentration, the lower the pH

Question 6

role of na+ ions

used in the co-transport of glucose and amino acids across cell membranes and transmission of nervous impulses

Question 7

role of Phosphate ions PO4^3-

Answer 7

essential components of DNA, RNA, nucleotides & ATP

Question 8

role of calcium ions Ca^2+

Answer 8

regulate protein channels, impulse transmission and harden body parts like teeth.

Question 9

role of potassium ions k^+

Answer 9

play a role in muscle contraction, nervous transmission, active transport and maintaining turgidity in plant

Question 10

role of Ammonium and nitrate ions

NH4^+ and NO^3-

Answer 10

part of the nitrogen cycle and a source of nitrogen for biological molecules

Question 11

role of Hydrogen carbonate ions

Answer 11

formed when carbon dioxide
dissolves in blood. They are important in the transport of
carbon dioxide in the blood and the regulation of blood pH
CO2 + H2O ⇌ HCO3– + H+
