Question

The yeast Saccharomyces cerevisiae has several genes encoding enzymes that function in the importation and metabolism of galactose.

a. True
b. False

Answer 1

True. The yeast Saccharomyces cerevisiae has several genes encoding enzymes that function in the importation and metabolism of galactose.

Step-by-step explanation:

True

The yeast Saccharomyces cerevisiae does indeed have several genes encoding enzymes that function in the importation and metabolism of galactose. This allows it to utilize galactose as a carbon source for energy production.

For example, one of the key genes involved in galactose metabolism in S. cerevisiae is GAL1. This gene encodes an enzyme called galactokinase, which phosphorylates galactose to galactose-1-phosphate. This is the first step in the metabolic pathway that ultimately leads to the production of ATP, the energy currency of the cell.
