Changing PH
3
Q

4
Q
Role of sodium ions in the body
A
Co-transport of glucose and amino acids
5
Q
Role of phosphate ions in the body
A
Component of DNA/RNA (phosphodiester bond) in nucleotides and ATP
phosphorylates other compounds usually making them more reactive
6
Q
How does the co-transport of glucose/amino acids work?
A
sodium moved out of cell by active transport
creates a sodium concentration/diffusion gradient
Affects water potential.
