Which type of molecule are enzymes?
Lipids
Carbohydrates
Nucleotides
Proteins
Enzymes only work with specific substrates because each enzyme:
Has an active site which only fits substrates with a particular shape.
Can only make ionic bonds.
Cannot change shape.
Becomes denatured when it is heated.
In the diagram of an enzyme reaction below, what is happening in step 2?
The enzyme is causing new bonds to form between the substrate
The substrates are beginning to bind to the enzyme
The active sites are restructuring the enzyme.
The catalyzed reaction is releasing a product.
This diagram shows what happens to lactose in the small intestine with lactase present
lactase
substrate
lactose
products
glucose + galactose
enzyme
Drag one of the two reactions to each of the catergories
Item 1
Item 2
Catabolic/Breaking Rx
Anabolic/Making Rx
1 substrate broken into 2 products
2 substrate bonded into 1 product
Would happen inside the small intestine/digestion
Would happen in the mammary glands of female mammals as part of the making milk for their newborns
