Inorganic ions Flashcards
What is the difference between organic and inorganic chemistry?
Organic chemistry is the study of molecules containing carbon atoms
Inorganic chemistry is the study of all other molecules
Where do inorganic ions occur?
Solution in the cytoplasm and body fluids of organisms
What is an alternative name for a hydrogen atom?
Proton
What does pH stand for?
Measure of the acidity or alkalinity of a solution
The higher the hydrogen ion concentration the lower the pH (acidic)
What does a low pH tell you about the number of hydrogen
Ions present?
Many hydrogen ions present
Why must the H in pH always be written as a capital letter?
H = chemistry symbol for hydrogen
How many iron ions does each molecule of haemoglobin contain?
4
What is the role of iron ions in haemoglobin?
Transport oxygen in the blood
What is cotransport?
Where two substances are transported across a membrane in the same direction at the same time by one protein
How do sodium ions help the absorption of glucose and amino acids in the digestive tract?
Sodium ions are needed in the uptake of glucose or amino acids through the epithetical cell membranes in the small intestine
What is the backbone of DNA?
Sugar-phosphate
What does ATP stand for?
Adenosine triophosphate
What is the difference between adenine and adenosine?
Adenine is a nitrogen base (also found in DNA)
Adenosine is adenine bound to a ribose sugar
ATP releases energy when the terminal phosphate group is released in hydrolysis - what 2 molecules are produced?
Adenosine diphosphate and phosphate group
