yes,if the yeast is not the bread will come out flat, i say this with previous experience.
The leavening of bread is the ingredient which aids in the rising process. Yeast is the typical leavening agent used to make bread. Depending on the bread, there are variations of yeast to choose from including active dry yeast and quick-rise yeast.

I haven't tried this yet - maybe this afternoon, but I found this conversion on a site called 'The Gooseberry Fool', so thanks to them. Yeast: The quantity of yeast recommended to raise 225g / 8 oz flour in a standard bread recipe is as follows: * 10g / 1/3 oz fresh yeast, or * 3.5g / 1/8 oz fast-action yeast = 1.5 teaspoons fast-action yeast or * 5g / 1/5 oz dried active yeast = 2 teaspoons dried active yeast Or you could use dried yeast instead! it isn't as firm and people say that it is much easier to use.
If you're using dried yeast, Yes. You can also buy active yeast in jars, generally in the refrigerator section and use that instead. However, it doesn't technically rise in warm water, the liquid allows the yeast to be reactivated. You can then add this to bread dough and the yeast digesting the sugar in the bread give off CO2 as a byproduct which allows the dough to rise and gives it those characteristic holes.
no you can't
If by dried you mean instant dry active you would use half the amount. So 7.5 grams.
Packaging. There is a difference though between dry yeast and rapid rise yeast. Dry or active dry yeast should be proofed (checked to see if still alive) first. Rapid rise yeast can be mixed with the dry ingredients. Follow the package directions.
There is yeast in all bread no matter how old it is. Yeast is what makes bread rise. It's a type of bacteria that creates air bubbles, making the bread rise and makes it nice and fluffy. There's different varieties of yeast as well. Wet, dry, active, fast rising, bread machine. So without yeast, you will have something that resembles a tortilla which would fit under the category of flat bread.
No they are not exactly the same, but very similar.Bread Machine Yeast is added to the dry ingredients, whereas Active Dry Yeast is added to the liquid.You can adding Active Dry Yeast to the warmed liquid (110-degrees or cooler) in the machine instead of adding Bread Machine Yeast on top of the dry ingredients. You however should not use the timed to bake later function if doing this.Also you can grind Active Dry Yeast to a finer powder using a spice mill or mortar and pestle.Also be aware that the weight of one teaspoon of Bread Machine Yeast as it is a finer powder and so more will fit in a teaspoon will be slightly different (+10%) from 1 teaspoon of Active Dry Yeast1 teaspoon Bread Machine Yeast = 3.11 grams1 teaspoon Active Dry Yeast = 2.83 gramsSo add 2 extra pinches of Active Dry yeast to correct the recipe.,______________________________Bread Machine Yeast is yeast that is ground into finer particles and so does not need to be dissolved in water like Active Dry Yeast and so you can add it along with the dry ingredients.Both Bread Machine Yeast and Active Dry Yeastrequire two rises of the dough.There is also Rapid RIse Yeast which has added enzymes and additives so only requires one rise.
The main ingredient in bread is yeast. This is an active bacteria. When mold starts on bread it continues until the bread is covered. The process of decomposition occurs
In order to activate the yeast and get it started growing. The yeast in the package has been dried out to make it dormant so that it can be stored.
Many yeasts are sac fungi, including the common yeast used to make bread. When the yeast is mixed with water and then warmed, the yeast cells become active.
