What is rate of metabolic co2 generation by human?

The rate of metabolic CO2 generation in humans varies based on factors such as age, sex, body composition, and activity level. On average, a resting adult generates approximately 200-300 milliliters of CO2 per minute. During vigorous exercise, this rate can increase significantly, potentially reaching up to 3-4 liters per minute. Overall, the metabolic rate of CO2 production is closely linked to the energy expenditure of the individual.
