Now you will carry out a lab to investigate this!
But firstly…..a review!
What is wrong with this table?Table showing oxygen:
Glucose CO2 produced Mean
1 2 31% .2 .4524 .4 0.1169
333332% 1.2 1.342 1 1.183% 3.5 1,3 3.5678
682.789
A table showing the volume of carbon dioxide produced by Saccharomyces cerevisae with different concentrations of glucose being utilised as the primary respiratory substrate
Glucose concentration (% volume)
Volume of CO2 produced (±0.01ml)
Mean volume of CO2 produced (±0.01ml)
Trials made
