EXPERIMENT 9 Flashcards
are Living organisms that help in fermentation
yeast
Provides nitrogen which serves as nutrition for yeasts
Pasteur’s salt solution
Produced when yeast and Pasteur’s salt solution are added to sugars
Carbon Dioxide (CO2) and Ethyl Alcohol (CH3CH2OH)
Catalyzes the fermentation of sugar into carbon dioxide and ethanol
Zymase
Causes hydrolysis of sugar solution to glucose and fructose
Invertase
act as catalytic substance speeding certain chemical reactions
enzymes
what are the two test conducted for the fermentation?
Iodoform test and benedict’s test
what test detects the presence of sugar? what is its indicator if its completed and not completed?
Benedict’s test, Completed no presence of Cu2O and if its incomplete presence Cuprous oxide (red precipitate)
used to test for presence of ethyl alcohol, what is its product?
iodoform test
are enzymes produced by yeast?
zymase and invertase
