  1. 1Cell activities depend on [blank_start]chemical reactions[blank_end] controlled by [blank_start]enzymes[blank_end].
    Enzyme production is controlled by [blank_start]DNA[blank_end].
    DNA is found in a cell's [blank_start]nucleus[blank_end].
    DNA codes for [blank_start]proteins[blank_end].
    [blank_start]Enzymes[blank_end] and [blank_start]hormones[blank_end] are made of proteins.
    Proteins are made up of [blank_start]amino acids[blank_end].
    Enzymes are [blank_start]catalysts[blank_end] that [blank_start]speed up[blank_end] reactions.
    Enzymes are [blank_start]specific[blank_end] to certain reactions.
    Enzymes work better at higher [blank_start]temperature[blank_end] and [blank_start]optimum[blank_end] pH.

  3. 31) The [blank_start]enzyme[blank_end] collides with a [blank_start]substrate[blank_end] and forms an [blank_start]enzyme substrate complex.[blank_end]
    2) [blank_start]Products[blank_end] are released.
    3) The enzyme is now free to [blank_start]collide[blank_end] again.

    Boiling [blank_start]denatures[blank_end] enzymes.
    pH's that are not the enzyme's [blank_start]optimum[blank_end] can alter the way the enzyme works.
    Both of the above change the [blank_start]shape[blank_end] of the [blank_start]active site[blank_end].
