1.8 Inorganic Ions Flashcards
How are ions gained
through nutrition
In what solutions do inorganic ions occur
in solution in the cytoplasm and body fluids of organisms, varying its concentration
what do pH values represent
the concentration of H+ in a solution
why do mitochondria accumulate H+ in the intermenebrane space
to allow aerobic respiration to take place
What are Fe2+ ions useful for
The central part of the haem group - allowing RBC to transport O2 and CO2
What is the use of Na+ ions (Sodium)
transport of Na+ ions across the cell membrane of cells in the intestine allows the co-transport of glucose and amino acids
What is the importance of phosphate ions?
- essential part of sugar phosphate backbone of DNA
- ATP (adenosine) can form ADP and release a phosphate ion + energy
- ADP can store energy by gaining phosphate ions and taking in energy
What does the transport of Sodium help
co-transport of glucose and amino acids
Which type of interaction is most common in water
hydrogen bonding
what property of water explains why sweating helps with the body temperature regulation
high heat of vaporisation
what property of water allows plants to transport water from the roots to the leaves fire the transpiration stream
Cohesive properties
