Unit 1 Biological Molecules (Inorganic ions) Flashcards
What are inorganic ions?
Inorganic ions are molecules that don’t contain carbon atoms and are charged atoms that play a major role in living organisms
How are ions gained through to the organism?
Ions are gained by the organism via nutrition
What maintains the optimum level of each ion?
Cytoplasm and body fluids maintain the optimum level of each ion
What is a factor that affects how the cytoplasm and body fluids maintain the optimum levels of ions?
The function of cell in which the cytoplasm and body fluids consist within
If the function of the cell changes how can the ion concentrations change?
Some ions are found in high concentrations while others are lower
What can happen if the ion concentration happens to increase?
The ion concentrations would increase leading to toxicity in the cell
What is the symbol for hydrogen ions?
H+
What else can be described as hydrogen ions?
Protons
What do pH values represent?
The concentration of hydrogen ions in a solution
What is the linkage between hydrogen ions and mitochondria as well as aerobic respiration?
Mitochondria accumulate hydrogen ions in the intermembrane space which allows aerobic respiration to occur
(E*) What is the intermembrane space?
The region between the inter and outer membrane of the mitochondria
What is the common symbol for Iron ions?
Fe 2+
What group and what specifically are Iron ions part of?
Iron ions are part of the haem group in the haemoglobin
How does Iron ions help haemoglobin?
Iron ions allow the formation of haemoglobin which helps more haemoglobin bind to Oxygen and Carbon Dioxide to transport them around the body.
What is the symbol of Sodium ions?
Na+
