Livers are p Hun Enzymes and p H

Livers are p. Hun! Enzymes and p. H

What the p. Hudge is p. H?

What the p. Hudge is p. H? /The p. H scale measures how strong an acid or a base is. /Any solution with a p. H lower than 7 is an acid /Any solution with a p. H higher than 7 is a base

The p. H scale /Vinegar, coke, and stomach acid are strong acids /Baking soda, ammonia, and bleach are strong bases

But what is it really? /p. H scale really measures the concentration of H+ ions vs. OH- ions

But what is it really? /H+ > OH- = acid /H+ < OH- = base /Li. OH -> Li + OH (base) /HCl -> H + Cl (acid)

Enzymes /Enzymes lower the energy needed for a reaction to take place. /Enzymes drive thousands of biologically necessary reactions - No enzymes = you die.

A mini puzzle /Enzymes are like puzzle pieces - they must fit exactly in order to work

But if the pieces don’t fit… /Other molecules, a change in temperature, or a change in p. H can change the shape of the active site, thus causing the enzyme to cease working.

But if the pieces don’t fit… /Change in shape (due to heat or p. H change) = enzyme denatured

Other factors affecting enzyme function • Competitive inhibition – Another molecule fits into the active site, thus preventing activity

Other factors affecting enzyme function • Allosteric inhibition – Another molecule binds to a different part of the enzyme, thus changing its shape and its function

So how does this relate?
