Yeast is a living organism that causes fermentation in flour to produce CO2 and alcohol. The carbon dioxide is what causes the mixture to rise.

But being a living organism yeast makes enzymes which are organic catalysts.

What are the importance of yeast?
yeast are the fermenters used in industries to ferment the substrate product.
What are the substrate for fermentation?
Substrate for fermentation is usually glucose. But depending on the yeast type it can be fructose or other monossaccharides too.
What substrate produces the most gas in yeast fermentation?
711 gas
What are the factors that affect fermentation rate?
age, temperture, ph, substrate, concentration
When bacteria perform fermentation what waste product is formed?
It depends on the type of substrate used; in alcohol or ethanol fermentation carbon dioxide is produced as byproduct. whereas in case of baker yeast CO2 is the sole product!
What substrate can yeast live on and feel well?
Yeast doesn't need a substrate. All it needs are the optimum conditions.

How does aspirin effect yeast respiration?
Stops substrate from getting to the active site
What percentage of respiratory substrate is oxidised in aerobic respiration of glucose by yeast?
Between 65-70%
What are the factors that affect fermentation rate?
age, temperture, ph, substrate, concentration
What temperature kills yeast?
Respiration requires enzymes to catalyze the oxidative breakdown of glucose, the respiratory substrate for respiration. Enzymes in yeast require an optimum temperature of about 30-40 degree Celsius. Hence temperature is closely tied to the rate of respiration in yeast.
What to enzymes do in an enzyme-substrate?
in an enzyme-substrate complex, the enzyme acts on the substrate .
Is NAD a substrate or a product?
Substrate.
The binding together of an enzyme and a substrate forms a what?
enzyme-substrate complex
What is it called when and enzyme and substrate come together?
The binding of an enzyme and a substrate forms an enzyme-substrate complex. It lowers the activation energy of a chemical reaction
