What are three factors that increase the rates of enzyme-controlled reactions?
Presence of:Competitive inhibitorsNon-competitive inhibitorsAllosteric sitesNegative feedback inhibitionIncrease/decrease of enzyme/substrateCooperativity
3 variables that can cause an enzyme to lose its ability to function?
An enzyme is a catalyst for chemical reactions. Three variables that can cause an enzyme to lose its ability to function are temperature, pH level and concentration.
How does the three-dimensional structure of trypsin affect its action as an enzyme?
it allows an inhibitor to block the active site of the enzyme
What are three that ways to control enzymes?
One way to control an enzyme is by altering the number of enzyme molecules. Two other ways are by altering the enzyme activity and compartmentalization.
Three pairs of enzyme-rich glands produce .?
Saliva A+

A series of enzyme-assisted chemical reactions that produces a three- carbon sugar molecule?
Calvin Cycle
What three things can alter the rate of an enzyme?
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
Who are the three conditions that effect the spanish soldiers in southwest?
Beer, food, women.
What three letters do enzyme end in?
-ase
What does enzymes functions depend on?
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
Altering the three-dimensional structure of an enzyme might?
prevent the substrate from binding the enzyme's active site
How does heating a enzyme affect its function?
For an enzyme to work it must bind to a specific substrate molecule, using a part of the enzyme molecule called the active site. To do this, the enzyme's active site and the substrate must have matching (complementary) shapes. The shape of an enzyme molecule depends on the exact way in which the molecule folds up. When enzymes are heated the weak bonds which hold the molecules in their precise shape are broken, and the enzyme molecule "unwinds" into a random shape. It can no longer bind with its substrate so it no longer has any activity. This "unwinding" of a protein molecule is called denaturation.
