pH is very important to living cells. That is because most living cells only survive in a very very specific range of pH. The smallest variation out of that range could cause the cell to die. That is mostly because proteins created by the cell become become denatured (dissociate, fall apart) when manufactured out of their pH range. Also extreme changes in pH can cause DNA to become denatured. or so ive been told....

∙ 15y agoOne reason is because enzymes can only function within a very narrow pH range. The control of the pH in organisms is often accomplished within buffers. I didn't understand this at first but it says it in our Biology textbooks =)

∙ 15y agoThe pH of a solution is a measure of its acidity / alkalinity. In an organism, biochemical reactions are carried out by enzymes, which are proteins. The shape of a protein molecule is dependent on the forces between its various parts. A drop in pH will cause some of the amino acids in the protein to pick up H+ ions with the reverse effect for a rise. The change in charge will alter the forces and hence the shape of the protein. A given enzyme has an optimal pH which allows its shape to be correct for the reactants to fit its active site. A shift from this value will reduce the efficiency of the enzyme and slow the reaction it is carrying out.

∙ 15y agobecause it needs to be neutral so there is no acid or alkaline in the cells

Why is it important that living things maintain constant internal temperature and pH values?
Other wise they die !
Why is it so important for cells to buffer solutions against rapid changes in pH?
Basically, it's because the fluids you take in all have different pH's. Naturally, this will change the pH values of your body. This is, obviously, not healthy for your body, so cells buffer the acidic or basic fluids you take in in order to keep you healthy.
What is the most important characteristic of living organisms?
All living organisms are composed of one or more cells.
What does the cell theory tell us about cells?
Cell theory states: -All living things are made up of cells. -Cells are the basic unit of structure and function in all living things. -Cells arise from pre-existing cells.
Why is organization in living things important?
Living things are complex. They require some kind of organization to carry out their life processes. In cells, cell organelles carry out these tasks and in multicellular organisms these are done by various cells.
Can cells function only in a narrow range of temperature and pH?
This is generally true. The allowable ranges vary from cell type to cell type, but extremes of temperature and pH will generally kill living cells.
How are cells important to the structure and function of living things?
cells are the basic units of sustaining functions in living creature
How does pH affect cells?
the slightest change in pH can destroy the substance or organism. The pH of a cell's interior helps regulate the cell's chemical reactions. For example, the pH of blood is 7.4, if blood falls to 6.8 or lower or 8.2 or higher, it results in death.
Protein catalysts which cause reactions to occur at temperatures and pH values common to living cells are?
Enzymes
Important source of energy for all living cells?
Glucose
Why are cells important to living things?
cause it helps you live

One important difference between living things and nonliving things is that only living things have?
cells
How are cells important to all forms of life?
They are important because we are all made up of cells. Your pets, your backyard, YOU! Cells are the basic building blocks of all living things. There are over one million cells swimming around in your body AT THE LEAST. So while you're reading this you're thinking, so I'm living because of the cells? Yes. One of the only reasons you're living is because of cells. Cells are living organisms too. Hope this helps!
Why Robert hookes discovery cells so important?
Because cells are the building blocks of every living thing.
What is the pH of your blood and your cells?
The pH of human blood is about 7.4.
What element is in makes up or is am important factor to all living things?
cells
