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.
What else can I help you with?
How can co2 production considered a measure of bmr?
CO2 production can be considered a measure of Basal Metabolic Rate (BMR) because the body's metabolic processes generate heat and energy during periods of rest. BMR is the amount of energy expended by the body at rest to maintain basic physiological functions, which involves the production of CO2 as a byproduct of cellular respiration. Therefore, measuring CO2 production can provide an indirect estimate of the body's metabolic rate and energy expenditure.
Why do germinated seeds produce carbon dioxide?
Because dry seeds have a very low metabolic rate and do not produce much Co2. Germinating seeds produce more Co2.
Why does measuring changes in O2 or CO2 allow you to measure metabolic rate?
Measuring changes in O2 or CO2 levels allows you to indirectly assess metabolic rate because oxygen consumption and carbon dioxide production are byproducts of cellular respiration. Higher rates of metabolism lead to increased oxygen consumption and carbon dioxide production, providing a way to estimate an organism's metabolic activity.
What kinds of things put more CO2 into the air?
Volcanism -- volcanoes -- are the greatest source of atmospheric CO2. After this, in varying degrees, are animal respiration, human energy generation, and transportation.
How much CO2 ppm do human lungs exhale on average?
It depends on a number of factors such as age, heart rate and depth of breathing. However, on average a human being exhales around 40,000 PPM of CO2.
Why does blood hydrogen ion concentration decrease as the body's metabolic rate decreases?
As the body's metabolic rate decreases, the amount of CO2 that is released into the blood stream decreases as well. The reduced amount of free CO2 means that there is less interaction with H20 which in turn reduces the amount of carbonic acid in the blood stream. With less carbonic acid, there is less neutralization, then there is less free hydrogen ions in the blood stream.
Is CO2 used in glycolysis?
No, CO2 is not directly involved in glycolysis. Glycolysis is the metabolic pathway that converts glucose into pyruvate, which can then be used in other pathways for energy production. Although CO2 does play a role in other metabolic processes in the cell, it is not a part of the glycolysis pathway.
How are the metabolic wastes of the human body excreted?
Metabolic wastes in the human body are excreted primarily through the lungs (carbon dioxide), kidneys (urea, excess minerals), and skin (sweat, small amounts of waste). The liver also plays a role in detoxifying and removing metabolic waste products from the bloodstream.
How much CO2 in liters does a human exhale per minute?
On average, a human exhales about 0.5 liters of carbon dioxide per minute at rest. This can increase during physical activity or in situations where higher metabolic rates are required.
Oxygen is generated by plants when they split what?
Human cells use oxygen and produce carbon dioxide, CO2, and water, H2O, in their metabolic reactions, whereas plants do the opposite in photosynthesis, in which 6 CO2 combine with 6 H2O to form 1 glucose and 6 O2.
Do plants absorb carbon dioxide?
Plants use CO2 in photosynthesis. They convert CO2 and H2O into carbohydrates through a series of metabolic pathways.
What is cellular production?
Cellular respiration produces CO2 and water as by-products of the metabolic pathway.
