Question

what are three ways that yeast use carbon (in the form of glucose)?

Answer 1

Yeasts use carbon obtained from glucose in three ways:

1. anabolism. Glucose catabolism in yeasts results in the formation of simple organic compounds (i.e., acetate) that are used for the production of biomass in the form of more complex biomolecules essential for yeasts metabolism. As a result, carbon is used to produce new bioorganic molecules in yeasts.

2. respiration. Under aerobic conditions, glucose catabolism results in the production of ATP in the processes of glycolysis and the citric acid cycle (TCA). These processes are associated with the respiration and release of CO2. As a result, during respiration, carbon is released by the yeasts in the form of carbon dioxide.

3. fermentation. Under anaerobic conditions, glucose catabolism results in the production of ATP, ethanol, and carbon dioxide. As a result, the consumed carbon is released by yeasts in the form of ethanol and carbon dioxide.
