Question

what does yeast produce during respiration​

Answer 1

Answer:

In summary, yeast is a single-celled fungus that uses cellular respiration, which converts glucose and oxygen into carbon dioxide and ATP. Remember that glucose is a simple sugar that provides energy to most lifeforms. This process is called aerobic respiration since it uses oxygen.

Definition of Yeast & Cellular Respiration

Picture a calm Sunday in the kitchen. The smell of freshly baked bread rises from the oven. By mixing yeast, flour, sugar, and water, you were able to turn these simple ingredients into a loaf of bread. If you've ever made bread you know it takes a long time. After mixing the dough, it needs time to rise. Almost like magic, your bread doubles or even triples in size over an hour or two. How does this happen?

The key ingredient for making fluffy bread is yeast. Yeast is a single-celled fungus, which is alive and must make its own energy to survive. The yeast in your bread uses a process called cellular respiration, where glucose is converted to ATP and carbon dioxide. The carbon dioxide is what causes the bread to rise. The yeast produces this gas and the bread puffs up, incorporating the gas in between the flour. Today, we'll learn about this process, which requires oxygen, called aerobic respiration, and another process of yeast called anaerobic respiration.

Aerobic Cellular Respiration

Aerobic cellular respiration is cellular respiration that requires oxygen. There are three main steps to this process: glycolysis, the citric acid cycle, and oxidative phosphorylation. Here, we will look at each step in more detail.
