==Key Stage 3==
===Meaning===
[[File:DigestiveEnzyme.png|right|300px|thumb|The '''digestive enzyme''' shown in purple attaches to the [[Substrate (Biology)|substrate]] which is broken down into two smaller pieces.]]
A '''digestive enzyme''' is a [[molecule]] made in the [[Digestive System|digestive system]] that breaks down large food [[molecule]]s into smaller [[molecule]]s.
===About Digestive Enzymes===
: There are different '''digestive enzymes''' for each [[nutrient]].
Some '''digestive enzymes''' you should know:
*[[Carbohydrase ]] - Breaks down complex [[Complex Carbohydrate|complex carbohydrate]]s into simple [[sugar]]s.*[[Protease ]] - Breaks down [[protein]]s.*[[Lipase ]] - Brakes Breaks down [[lipid]]s (fats and oils). ==Key Stage 4=====Meaning===A '''digestive enzyme''' is an [[enzyme]] which is used to break down large insoluble [[molecule]]s into smaller [[soluble]] [[molecule]]s. ===About Digestive Enzymes===: '''Digestive enzymes''', like all [[enzyme]]s, are made of [[protein]]s.: '''Digestive enzymes''' work as a [[catalyst]] for the breakdown of large [[molecule]]s.: '''Digestive enzymes''' are shaped to work on only one [[Substrate (Biology)|substrate]]. This called the [[Lock and Key Model]].Some '''digestive enzymes''' you should know:*[[Carbohydrase]]s - [[Salivary Amylase]], [[Pancreatic Amylase]] and [[Amylase]].*[[Protease]]s - [[Pepsin]], [[Trypsin]] and Peptidase*[[Lipase]] {| class="wikitable"|-| style="height:20px;
