It is true that yeast bread can be baked in a microwave oven. However, the results are not always good.
Yeast, which is used in breads is your answer. While the bread it's in must be baked in an oven, the yeast itself can not be baked alone. Yeast also must be stored in a cool, dark place and kept out of bright sun, which will kill the yeast.
Non-rising yeast does exist. It can be used to make no-rise rolls and other baked goods. Generally, people will use rising yeast to make their breads.
a yeast dough uses yeast and a quick bread uses baking powder or baking soda.

Many baked goods that are not raised with yeast contain baking power; some of the most common are biscuits, muffins (USA), cookies, quick breads, cakes and crackers.
Not all breads are baked at 200. Sweetened breads are usually baked 180-190 degrees Celsius. Savory breads are usually baked around 230 degrees C.
Gluten is developed in yeast breads when the flour is mixed with water.
Quick breads such as muffins, unlike yeast breads, can be baked immediately after the ingredients are mixed. In other words, there is no need to wait for leavening to occur before baking the muffins because they rise during baking. Therefore, they are relatively quick to make. Yeast breads on the other hand require a lot of time for leavening before baking and are much more time consuming.Source: "Understanding Food" by Amy Brown

Quick breads get their name because they are leavened with baking powder or baking soda rather than yeast, allowing them to rise quickly during baking. This means they can be prepared and baked in a shorter time frame compared to yeast breads, which require longer fermentation and rising periods. As a result, quick breads are often easy and fast to make, making them a popular choice for home bakers.
