substances that accelerate or promote chemical reactions
biologically active catalysts that facilitate chemical changes in the human body by decreasing the activation energy of chemical changes
the depressed or grooved region in an enzyme
the active site accommodates the ___________
when the shape of the active site permits only a single substrate or type of substrate
a nonprotein structure that may be either an inorganic or organic substance associated with a particular enzyme of enzyme reaction
organic cofactors
The given name of an enzyme is usually based upon the substrate name and the suffix ___
occurs when so much substrate is present that all enzyme molecules are engaged in chemical reactions, resulting in no further increase in reaction rate
substances that bind to an enzyme and turn it off, thus preventing it from catalyzing the reaction
a substance that resembles the substrate and binds with the active site of the enzyme, thus interfering and preventing the substrate from binding. The amount of substrate relative to the amount of competitive inhibitor determines the degree of inhibition
a substance that does not resemble the substrate and inhibits enzymes by binding to a site on the enzyme other than the active site and thus changing the shape of the active site. This type of inhibition is not influence by the concentration of substrate. Also known as allosteric inhibitors.
the place where most noncompetitive enzymes bind
involves numerous enzymes that subsequently convert a substrate to a final product. The product of one enzyme is the substrate for the next enzyme in the pathway
a structure composed of enzymes physically linked to convert a substrate to a final product

Frequently Asked Questions

What is a crossword?

Crossword puzzles have been published in newspapers and other publications since 1873. They consist of a grid of squares where the player aims to write words both horizontally and vertically.

Next to the crossword will be a series of questions or clues, which relate to the various rows or lines of boxes in the crossword. The player reads the question or clue, and tries to find a word that answers the question in the same amount of letters as there are boxes in the related crossword row or line.

Some of the words will share letters, so will need to match up with each other. The words can vary in length and complexity, as can the clues.

Who is a crossword suitable for?

The fantastic thing about crosswords is, they are completely flexible for whatever age or reading level you need. You can use many words to create a complex crossword for adults, or just a couple of words for younger children.

Crosswords can use any word you like, big or small, so there are literally countless combinations that you can create for templates. It is easy to customise the template to the age or learning level of your students.
