Adding sugar to fresh yeast before it is exposed to heat can strengthen the yeast. When sugar is present, it serves as a food source for the yeast, allowing it to become more active and produce carbon dioxide and alcohol through fermentation. This fermentation process is crucial for the rise in bread-making, as the carbon dioxide created helps the dough to expand and develop a light, airy texture.

When yeast is given sugar before being subjected to heat, it can also increase the yeast's vitality and efficiency. A more vigorous fermentation will result in better dough performance, leading to improved flavor and texture in the final baked product.

Other reactions like inhibition of growth, prevention of yeast from dying, or having no effect would not accurately describe the beneficial interaction that occurs between sugar and yeast in this scenario. The presence of sugar actually enhances yeast activity, contributing to successful baking outcomes.
