A yeast culture produces 0.60 g of carbon dioxide per minute for 15 minutes under anaerobic conditions. Which statement correctly links the result to the pathway?
The culture produces 0.040 g in total because oxygen limits aerobic respiration
The culture produces 9.0 g in total and ethanol is also formed from glucose
The culture produces 9.0 g in total and lactic acid is also formed from glucose
The culture produces 40 g in total because carbon dioxide is stored in the glucose
