During exposure to elevated glucose, a yeast cell will increase its uptake of glucose. Describe the mechanism by which the yeast senses the extracellular glucose.

A. By glucose diffusing into the nucleus and binding to transcription factors
B. By glucose binding to glucose receptors
C. By the increase in energy inside the cell when the glucose is metabolized
D. By glucose uptake through glucose transporters

Yeast cells sense extracellular glucose through the mechanism involving glucose uptake through glucose transporters. When yeast cells are exposed to elevated glucose levels, they increase their glucose uptake by utilizing glucose transporters present in their cell membranes. This process allows them to efficiently sense and respond to changes in their external glucose environment.
