What is the total pH of a human being

What is the total pH of a human being?
If i take a living human being, put it in a giant blender and blend until the texture is like a hammered-on banana, what would be its pH value?

i would also say around 7. But ya i hope no1 knows the answer to this question with certainty

around 7..... maybe no one know the answer correctly...

If you were to do this, how much liquid would result: Blood = about 5 litres buffered near neutral pH Stomach acid = about 250ml - very acidic, pH = 0.5-1.0 This is HCl strong acid Urine in bladder. = about 1 litre = near neutral pH If you combine these posssible sources of fluid, the stomach acid will have a strong effect and produce a solution where the pH is probably about 2-3 . But this is really an educated(?) guess.

If a strong acid has a pH of 1, a strong base has a pH of 14, and water has a pH of 7, does catalase work

If a strong acid has a pH of 1, a strong base has a pH of 14, and water has a pH of 7, does catalase work...?
1. If a strong acid has a pH of 1, a strong base has a pH of 14, and water has a pH of 7, does catalase work best in an acid, base, or neutral environment? Explain. 2. Predict ways in which pH affects the chemical reactions in living cells.

Think about the structure of catalase. Enzymes are just protein, and proteins have specific ranges of pH in which they work best. Generally speaking, extremely acidic or basic conditions risk denaturing proteins, however each is different. This will help in answering both questions.
