If Enzyme 3 is denatured, the levels of which substance will increase?

• Lactose

• Galactose

• Galactose-1-phosphate

• Glucose-6-phosphate

Freshly picked corn tastes sweet because of the high sugar content in the kernels. Within one day after picking, however, about 50% of the sugar in the kernels is converted to starch. To preserve the sweetness, freshly picked corn can be immersed in boiling water for a few minutes, and then cooled.

• Boiling deactivates the enzyme responsible for converting sugar to starch

• Boiling kills a fungus on the corn that is needed to convert sugar to starch

• Boiling destroys sugar molecules so they cannot be converted to starch

• Boiling activates the enzyme that converts amino acids to sugar

The diagram below illustrates the cyclic formation and breakdown of the molecule adenosine triphosphate (ATP). What happens when the chemical bond that attaches the third phosphate group to the molecule is broken?

• Energy is released which is available for cellular activities

• Energy is stored in the third phosphate group

• Energy is lost to the cell and is transferred as heat

• A molecule of adenosine monophosphate (AMP) is formed
