The substrate (dipeptide) would be broken down into products (amino acids) faster.

The products (amino acids) would combine faster.

The substrate (dipeptide) would not be broken down into products (amino acids).

The products (amino acids) would combine slower.

The sweet taste of freshly picked corn is due to the high sugar content in the kernels. Enzyme action converts about 50% of the sugar to starch within one day after picking. To preserve its sweetness, the freshly picked corn is immersed in boiling water for a few minutes, and then cooled.
Which statement most likely explains why the boiled corn kernels remain sweet?

Boiling activates the enzyme that converts amino acids to sugar.

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

Boiling deactivates the enzyme responsible for converting sugar to starch.

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

The p53 gene in mammalian cells is known to stop the cell cycle in response to damaged DNA. If this gene is damaged without repair, which of the following is most likely to occur?

The cell will immediately undergo apoptosis.

Growth factors will allow the cell to divide normally.

The cell cycle will be disrupted in the defective cell.

Damaged DNA will remain unrepaired and a tumor may form.

Cells pass through multiple checkpoints before entering mitosis. If DNA damage is detected, the cells do not enter mitosis until the damage is repaired.
Why does the damaged DNA need to be repaired before the cell enters mitosis?

For the cytoplasm to divide equally between the two daughter cells.

For healthy daughter cells to be produced, allowing the organism to continue growing.

For chromosomes to properly align at the metaphase plate during mitosis.

For synthesis to create multiple copies of DNA as emergency storage of information.
