Is It True, that all functional proteins (enzymes, hemoglobin, etc.) are influenced by hydrogen ion concentration therefore nearly all biochemical reactions are influenced by the pH (potential for Hydrogen) of their fluid environment. Acid-base balance of body fluids is critical and closely regulated.
True
Water and all water solutions both have ______________ and _____________.
hydrogen ions (H) hydroxide (OH ).
It indicates a fluid’s hydrogen ion concentration.
A pH followed by a number
It means an equal concentration of H and OH
A pH of 7.0
A pH higher than 7.0 indicates an _________ solution (base)
alkaline
A pH that indicates an acid solution.
a pH lower than 7.0
What is the pH of arterial blood?
7.4
The pH of venous blood and interstitial fluid is 7.35. While, the intracellular fluid is:
averages 7.0
keeping the concentration of hydrogen ions in the body relatively constant.
acid - base balance
