Yeast Lecture 1 Flashcards
1
Q
Why does Saccharomyces cerevisiae have so many more genes than S. pombe?
A
Due to a whole genome duplication
2
Q
What are some properties of S. cerevisiae?
A
Can be haploid or diploid
3
Q
What happens if sufficient glucose is present for S. cerevisiae?
A
Exclusively Glycolysis and Alcohol fermentation -> releases CO2 and Ethanol
4
Q
What is catabolite repression?
A
Represses Respiration and other carbon sources under sufficient glucose
5
Q
How does a normal S. cerevisiae growth phase look like?
A
biphasic growth curve
Start with Lag phase -> Exponential phase -> Post diaauxic phase -> stationary phase
6
Q
What is the diaauxic shift?
A
Start of Glucose usage and Ethanol production
