INORGANIC IONS Flashcards
1
Q
WHAT ARE INORGANIC IONS REFERRED TO AS?
A
MINERALS
2
Q
WHAT ARE INORGANIC IONS IMPORTANT FOR?
A
CELLULAR PROCESSES
3
Q
WHAT ARE THREE EXAMPLES OF CELLULAR PROCESSES?
A
- MUSCLE CONTRACTION
- NERVOUS COORDINATION
- MAINTAINING OSMOTIC PRESSURE (CELLS + BLOOD)
4
Q
WHAT IS THE DEFINITION OF ‘INORGANIC’?
A
A MOLECULE / ION THAT HAS NO MORE THAN 1CARBON ATOM
5
Q
WHAT IS THE DEFINITION OF ‘ORGANIC’?
A
MOLECULES THAT HAVE A LARGE PROPORTION OF CARBON AND HYDROGEN ATOMS
6
Q
WHAT IS THE DEFINITION OF ‘MICRONUTRIENTS’?
A
NEEDED IN MINUTE (TRACE) CONCENTRATIONS E.G. COPPER AND ZINC
7
Q
WHAT IS THE DEFINITION OF ‘MACRONUTRIENTS’?
A
NEEDED IN SMALL CONCENTRATIONS
8
Q
WHY IS MG2+ AN IMPORTANT MACRONUTRIENT?
A
- COMPONENT OF CHLOROPHYLL
- ESSENTIAL FOR PHOTOSYNTHESIS
- NO MG2+ = CAN’T MAKE CHLOROPHYLL
- NO CHLOROPHYLL = YELLOW LEAVES (AKA CHLOROSIS)
9
Q
WHY IS FE2+ AN IMPORTANT MACRONUTRIENT?
A
- COMPONENT OF HAEMOGLOBIN
- HAEMOGLOBIN IS FOUND IN RED BLOOD CELLS
- NEEDED TO TRANSPORT OXYGEN
- LACK OF IRON = LEAD TO ANAEMIA + FATIGUE
10
Q
WHY IS CA2+ AN IMPORTANT MACRONUTRIENT?
A
- IMPORTANT FOR STRENGTHENING THE BONES AND TEETH
- HARDENS BONES DUE TO OSSIFICATION
- PROVIDES STRENGTH TO PLANT CALL WALLS
11
Q
WHY IS PO43- AN IMPORTANT MACRONUTRIENT?
A
- COMPONENT OF NUMEROUS BIOLOGICAL MOLECULES
- E.G. ATP, PHOSPHOLIPIDS, DNA, RNA
