The specific growth rate of a yeast having a doubling time of 0.693 h (roundedoff to nearest integer) is___________h-1

Why do you think yeast mass increases rapidly initially and then plateaus (remains the same)?2 marks

A bacterial strain is grown in nutrient medium at 37 ˚C under aerobic conditions.The medium is inoculated with 102 cells from a seed culture. If the number ofcells in the culture is 105 after 10 hours of growth, the doubling time of the strain(rounded off to nearest integer) is ____________h

Consider the growth of S. cerevisiae under aerobic condition in a bioreactor andthe specific growth rate of yeast is 0.5 h-1. The overall reaction of the process is2C6H12O6 +0.2NH3+10.35O2  CH1.8O0.5N0.2+0.2C2H6O+10.6CO2+10.8H2OThe heat of combustion values for different compounds are tabulated below withthe reference to CO2, H2O, O2, and N2 at standard conditions.Compound Heat of combustion(kJ mol-1)C6H12O6 2802NH3 383CH1.8O0.5N0.2 560C2H6O 1366The specific rate of heat production (rounded off to nearest integer) is_____________ kJ mol-1 h-1.

Resources are plentiful initially so yeast population size increases rapidly. This is an e increase.

Students are studying the capability of yeast to produce carbon dioxide through cellular respiration. The amount of carbon dioxide produced by the yeast in the study over time is shown below.Time (ss) Carbon Dioxide Produced (mLmL)000030301160602290904412012066150150991801801111How should the student best present this data to their classmates?Elimination ToolSelect one answerAWith a video explaining the results.BWith a graph showing carbon dioxide production over time.CWith a table explaining the characteristics of the yeast in the study.DWith a research paper explaining the background information.
