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.

β 12y agobecause changes in pH have so many effects on the rates of chemical reactions, and it can, like temperature, make enzymes and the active sites inactive

What substance resist pH change?
A SolutionA Solutiona solution However: Mastering Biology by Pearson says that the answer is a BUFFER. Do NOT select "solution," as that is incorrect.
Why are buffers important in Chemistry and Biology?
Because they help maintain homeostasis within an organism by keeping pH at a nearly constant value. This is important because in humans, for example, a pH shift of about only about .4 units is fatal.
What are compounds that resist changes in pH?
A buffer resists pH change.
What allows you to eat acidic foods without changing your blood pH?
The buffers present in blood resist small changes in pH. The most prominent are phosphate and carbonate buffers in blood.
What changes the pH levels of soaps?
The pH depends on the ingredients.
Why is important to choose an indicator that changes colour at a right pH?

Why are enzymes mixed with vinegar less effective?
Enzymes are sensitive to changes in pH and only work with a relatively small pH range. Since vinegar is an acid, the pH of the solution containing the enzymes is changes when vinegar is added.
If the pH of the small intestine changes will it harm you?
If the pH of your small intestine is abnormal, it can harm you. Your intestines, liver, etc. can not assimilate important vitamins, minerals and food supplements when the pH is higher or lower. If the pH has too little alkaline, for example, it cannot heal itself, leaving open internal and external wounds for extended periods of time until alkaline is restored, which is difficult to do.

What changes color on pH?
a pH indicator
What are compounds that resist changes in pH?
A buffer resists pH change.
How is the pH level of a substance affected by buffers and why are buffers important in the human body?
Buffers "slow" changes in pH (they make it difficult to change pH), and for animals a constant pH (internally) is critical to survival. (A change in pH of 1 - in either direction - will kill you.)
What stops sudden changes in ph?
A buffer solution.

The buffers present in blood resist small changes in pH. The most prominent are phosphate and carbonate buffers in blood.

The pH depends on the ingredients.
Why is it important to maintain the pH 6 to 8?
We all know that biology can be tough sometimes but you have to think of it as this way, as a biology teacher I think that all learners should try my method. The following answers your question. If you make the pH 5 then it ill be too low for the alkali or acid to reveal its colour but if you put it at 9 it is too high. So to be safe the pH always needs to be 6-8.
