The shape of an enzyme determines its function because enzymes are SPECIFIC to a substrate.
Enzymes are proteins that speed up chemical reactions.
Each enzyme binds to a specific substrate in order to speed up the rate of a chemical reaction.
An enzyme binds to a specific substrate through its active site in order to form the enzyme-substrate complex.
This feature of the enzymatic activity is known as specificity.
In conclusion, the shape of an enzyme determines its function because enzymes are SPECIFIC to a substrate.

The statement that suggests that the shape of an enzyme determines its function, would be the fact that enzymes are specific to certain substrates, depending on the particular shape of an enzyme it can allow binding to specific substrates and allow for catalyzing that corresponding reaction.

What are enzymes also known as? What do enzymes do to biological reactions? What do we call the special shape on an enzyme molecule? What are enzymes made of? What is created when an enzyme and a substrate combine together? What is lost when an enzyme is denatured? What 2 factors cause denaturing? Where exactly are the enzymes involved in aerobic respiration found? Two processes catalysed by enzymes? Is it possible to kill enzymes? What is digestion? Where is lipase produced and what good group does it break down?
