To be activated, yeast needs warmth, water, and sugar.
Yeast needs warmth, moisture and some form of sugar to be active and make carbon dioxide gas.
dry yeast does not become active until it is in contact with water fresh yeast is active all of the time

1 (6-ounce) cube or cake of compressed yeast (also know as fresh yeast) = 1 package of active dry yeast 1 package active dry yeast = about 2 1/4 teaspoons = 1/4 ounceTherefore, 1.5 ounces of compressed yeast = 1/16 of an ounce of active dry yeast or 1/4 of the package of active dry yeast.
A packet of active dry yeast typically contains about 2 1/4 teaspoons of yeast.
Yeast needs an appropriate temperature, water, and sugar to be active. If it does not have those three things, it will be inactive.
Instant yeast is another type of dry yeast that was introduced after active dry yeast in the 1970s. It is made using a similar process as active dry yeast, although is dried more quickly. As you can see, this yeast is also milled into finer particles. Because of this, it dissolves faster and activates quickly. But unlike active dry yeast, instant yeast doesn't have to be proofed first; it can be mixed straight into the dry ingredients with the same result. This yeast also gives you two separate rises and it can be used interchangeably with active dry yeast.
A typical packet of active dry yeast contains about 2 1/4 teaspoons of yeast.
One packet of active dry yeast typically contains about 2 1/4 teaspoons of yeast.
1 1/2 tsp rapid rise yeast equals 2 tsp of active dry yeast
So that the yeast has food to grow.
Yes, you can substitute rapid yeast (also known as instant yeast) for active dry yeast, but the quantities and method of incorporation may differ slightly. Typically, you can use the same amount of rapid yeast as active yeast, but there's no need to proof rapid yeast in water before using it. Instead, you can mix it directly with the dry ingredients, which can save time in the baking process.
