As lactose approaches the active site of lactase, as shown in the image, which of the following occurs first? The lactose molecule is broken into glucose and galactose.
Lactase shifts to its lowest free energy level to allow lactose to enter the active site.
Lactose creates a microenvironment as it approaches lactase to promote binding.
Temporary bonding occurs between the active site and the substrate, causing a conformational change.
