Question
**Question 31** Yeasts are single-celled organisms that can grow in aerobic or anaerobic conditions. Explain how and why a yeast population growing in an aerobic environment would be affected if the environment suddenly became an anaerobic one. In your discussion, address energy, growth rate, and gene expression. --- **Explanation:** This question requires you to explore the metabolic flexibility of yeast cells, focusing on how they adapt to changes in oxygen availability by altering their energy production, growth rate, and gene expression. Yeasts primarily use aerobic respiration when oxygen is present, which efficiently generates ATP from glucose. However, in the absence of oxygen, yeast cells switch to anaerobic fermentation, leading to less efficient ATP production and the formation of ethanol and carbon dioxide as byproducts. This switch impacts growth rates, as anaerobic conditions generally result in slower growth due to reduced energy yield. Furthermore, gene expression changes significantly as yeast populations alter the expression of genes associated with metabolic pathways to adapt to anaerobic conditions, increasing the expression of genes involved in fermentation and decreasing those related to respiration. Understanding these physiological and genetic adaptations can provide insights into yeast biology and its applications in biotechnology.
