well...too much CO2 in the body means there's a high H+ concentration.... which means there's low pH.

Why are small changes in pH so important in biology?
Changes in pH are really changes in the concentration of hydrogen ions in solution. Naturally, with so many enzyme and biomolecular reactions critically dependent on relative ionic strength and potentials it is little wonder that changes in one of the main drivers of inter-molecular interaction affects the biological system.
What is homeostasis how does relate carbon dioxide?
As we perform cellular respiration, the byproduct carbon dioxide builds up in our blood. This is a problem, since it lowers the pH of blood, and pH is one of the factors that we must keep in homeostasis. So, as CO2 rises, blood pH falls, and breathing rate increases, allowing more CO2 to leave they body, and allowing blood pH to rise back to the pH set point.
How do extreme pH and temperature extremes affect enzymes?
Enzymes operate best under a tight, optimal range of pH values. Extreme pH can seriously affect enzyme activity, so it is little wonder that big changes in pH can slow down enzyme activity. Extreme changes can often irreversibly inactivate and denature an enzyme.
Is blood a pH buffer?
Blood itself is not the buffer. Hemoglobin is, controlling the pH because it binds to oxygen, carbon dioxide, and most importantly hydrogen ions. If hydrogen ions were produced without hemoglobin, the pH would rise very quickly and the human body would fail.
How do the kidneys help to prevent blood pH from rising?
If blood pH is too low (ph < 7.35 ) = acidosis If blood pH is too high (pH > 7.45) = alkalosis In alkalosis: at the intercalated cells of the collecting duct the following occurs: secretion of Hco3- (via Hco3- / cl- antiporters) into the glomerular filtrate, which ultimately forms the urine. Rebsorption of Hydrogen ions (via ATPase dependant proton pumps)
How does exercise affect the pH of blood in living organism?
Too much exercise causes the body's pH to drop. The pH of the blood should be maintained at 7.4. If the pH drops below 6.8 or rises above 7.8, death may occur. Fortunately, we have buffers in the blood to protect against large changes in pH. Exercise can cause dangerous drops in pH, so listen when your body screams for a rest.
Is blood alkaline or acidic?
pH of blood is 7.46,so it's alkaline though slightly
Why is your son having so many nose bleeds?
This is a common problem for teenage boys. They grow out of it. The nose is sensitive to many different changes, including temperature and blood sugar levels.
Can raising your Ph level above 7.5 help in the treament of cancer?
The theory that this concepts relies on is that by changing the Ph of the body, you will invariably destroy the cancer cells in the body. However, research has shown that th good cells can be just as sensitive to these changes in Ph levels. So if you attack the cancer cells, you will also be destroying the good cells in the body at the same time.
Blood has a pH of 7.35 to 7.45. gastric juice has a pH of about 2.0. the more alkaline fluid is?
Higher is the pH value more alkaline is the fluid so Blood is more alkaline.
What would you expect the pH of blood to be?
its very acidic so i would say like a 9 or 10
How does exercise affect the pH of blood in a living organism?
The decease in pH is caused often by an increase in C02 levels, so the body reacts by increasing the rates of respiration so as to flush out the C02 from body back into the atmosphere. In addition the renal and alimentary system increases the rate of excretion of NaBicarbonate which removes H+ from the body. C02 + H20 <=> H+ + HC03-
What is the pH range of the blood?
It's slightly alkaline and on an average is measured as 7.3 but ranges from: 7.2-7.4The normal pH of blood running through arteries (large elastic-walled blood vessels that carry blood from the heart to other parts of the body) is 7.4; the pH of blood in the veins (vessels that transports blood to the heart) is about 7.35.The measure of acidity of a substance is known as pH. Pure water, which has pH of 7, is neutral. Substances with a pH less than 7 are considered acidic and substances with a pH of greater than 7 are considered basic or alkaline. The normal pH of blood running through arteries (large elastic-walled blood vessels that carry blood from the heart to other parts of the body) is 7.4; the pH of blood in the veins (vessels that transports blood to the heart) is about 7.35. Normal urine pH averages about 6.0. Saliva has a pH between 6.0 and 7.4.Blood is between 7.36 and 7.41 pH, depending on whether it's arterial or venous. So it's fairly neutral.arterial blood pH = 7.41 (outgoing from heart)venous blood pH = 7.36 (returning to heart)
What happens if you mix bromphenol blue and NaOH?
Bromophenol blue pH indicator changes from yellow at pH 3.0 to blue at pH 4.6; it turns blue even in neutral water (pH=7) so when NaOH is added nothing really changes: blue = blue
Why is your vaginal pH so high after having your period?
Because the Ph of blood is 7.4, much higher than the normal vaginal Ph of about 4.5.
What color does the pH paper change in orange juice?
The pH of orange juice varies from about 3.3 to 4.2, which makes it weakly acidic. This would be orange on many UI papers, but they do vary so always compare the colour with the chart supplied.
What are some buffer solution inside the human body?
Bicarbonate & CO2 dissolved in the blood act as buffers. They make it so the pH of the blood doesn't change much. It's important because the hemoglobin of the red blood cells changes its conformation (shape) when the pH changes. If the hemoglobin changes its shape, it won't transport oxygen, and you die... There's a medical condition for this - 'acidosis' - it's when you're body isn't efficiently getting rid of CO2, and the blood gets too acidic to transport oxygen properly. Potentially, it's potentially a life-threatening condition.
