Exam 4: Acid and Base Flashcards
how does phosphoric acid get created
from breakdown of phosphorous- containing proteins
how is lactic acid created
from anaerobic glycolysis
how do ketone bodies and fatty acids get created
from triglyceride catabolism in postabsorptive state
What are the three chemical buffer systems
bicarbonate, phosphate and proteins
What are the two physiological buffer systems
respiratory and renal
How long does the chemical buffer system take
nearly instant
how long does the respiratory buffer system take
1-3 minutes
how long does the renal buffer system take
hours to days
WHat affects hydrogen ion concentration
acids and bases
When a base is protonated, is this the same thing as being reduced? Why or why not?
no because the difference is picking up a proton or picking up a proton and a electron
What is the functional purpose of buffers
to keep your pH from swinging severly
In a buffer what does the acidity reflect on
only the free H’s in the solution
How do buffers control pH
release hydrogen ions if pH rises and bind hydrogen ions if pH falls
The carbonic acid- bicarbonate system is an important buffer system for what
blood
How does carbonic acid rate on the base/ acidity scale
weak acid
