Why does yeast respiration happen?
Yeast respiration occurs as a way for yeast cells to generate energy for survival. Through respiration, yeast cells break down sugars to produce ATP, which is used as an energy source for cellular processes. Oxygen is typically needed for efficient respiration to occur, but yeast can also undergo fermentation in anaerobic conditions to generate energy.
Do yeast have mitochondria and can they perform cellular respiration?
Yes, yeast have mitochondria and can perform cellular respiration.
What determines whether yeast ferments or respires?
Yeast will ferment in anaerobic conditions (without oxygen) to produce energy in the form of ethanol and carbon dioxide. In aerobic conditions (with oxygen), yeast will respire using oxygen to generate energy in the form of ATP.
What are the two types of anaerobic respiration?
The two types of anaerobic respiration are lactic acid fermentation and alcoholic fermentation. Lactic acid fermentation occurs in muscle cells during intense exercise, while alcoholic fermentation is used by microbes like yeast to produce ethanol and carbon dioxide.
Alcoholic fermentation occurs most commonly in which types of organisms?
Alcoholic fermentation occurs most commonly in yeast and some bacteria. Yeast uses this process to produce alcohol and carbon dioxide during the breakdown of sugars.
What occurs during the first stage of respiration?
Glycolysis occurs in the cytoplasm during the first stage of respiration.

When do green plants carry on respiration?
both photosynthesis and cellular respiration occurs during the day, however, during the night when there is no sunlight only cellular respiration occurs.
What are facts about ethanol?
during anaerobic respiration in yeast and bacteria ethanot is the by product
Reduction of oxygen which forms water occurs during?
The reduction of oxygen that forms water occurs during respiration. It occurs when oxygen and hydrogen mix to form what is called metabolic water.
What chemical substance do yeast consume?
Yeast uses sugar in respiration.Glucose is the primary substrate.This is oxidized during respiration
Do yeast have mitochondria and can they perform cellular respiration?
Yes, yeast have mitochondria and can perform cellular respiration.
When Cells use oxygen to release energy during?
Cells don't do fermentation, the yeast does. Cells don't do fermentation, the yeast does.
Carbon dioxide ethanol and energy are the products when anaerobic respiration occurs?
During anaerobic respiration, carbon dioxide and ethanol are produced in certain organisms like yeast, while in others, lactic acid is produced. This process is less efficient than aerobic respiration and produces less energy in the form of ATP.
How yeast excrete?
Yeast excrete CO2 after they undergo respiration.
Could yeast still produce CO2 if it was performing aerobic respiration?
No, yeast does not produce carbon dioxide (CO2) during aerobic respiration. In aerobic respiration, yeast uses oxygen to completely break down glucose into carbon dioxide and water, resulting in CO2 as a byproduct. However, the process is more efficient than anaerobic respiration, where yeast ferments sugar and produces both ethanol and CO2. So, while CO2 is produced in aerobic conditions, it is not the primary energy-generating pathway for yeast.
What is Anaerobic respiration in a yeast cell with anaerobic respiration in a muscle cell?
Anaerobic respiration in yeast cells occurs through a process called fermentation, where glucose is converted into ethanol and carbon dioxide in the absence of oxygen. This process allows yeast to generate energy efficiently in low-oxygen environments, commonly used in baking and brewing. In contrast, anaerobic respiration in muscle cells results in the production of lactic acid when oxygen levels are insufficient during intense exercise, leading to temporary energy production. While both processes provide energy without oxygen, the end products differ: ethanol and CO2 in yeast and lactic acid in muscle cells.
