do you think you can produce more carbon dioxide when you are sitting or when you are running?

If you have enough oxygen, your body uses aerobic respiration for its energy needs. Aerobic respiration produces carbon dioxide. Anaerobic respiration is reserved only for when you don't have enough oxygen to do aerobic respiration, which happens after you start to run a bit. Anaerobic respiration does not produce carbon dioxide. However, you also do aerobic respiration at the same time even after running a while, only less because you only have as much oxygen as you keep breathing in. So the answer is running, because aerobic respiration increases when you need the energy.

you COULD be....\n\nyour body will burn all the carbs in your body first (since they are easiest to break down for energy).  it stores roughly 800 calories max for later use like working out.  \nonce it burns away most of the carbs, then it will start burning down fat (stored calories).  \n\nso if you run, at the beginning you'd just be burning mostly carbs (roughly 0-20 mins),  50% carbs/50%fat burning (20-40min), and 20% carbs/80% fat burning (40-60min).  so try to stay in your aerobic zone for as long as you can...if you want to target the calories from fat.

You do because you raise your metabolism and then you are using more energy thoughout the day. I would reccommed eating a bowl of oatmeal and then going for a run, you may want to include a few sprints to really jack your metabolism. Or if you are good at it(can do it without keeping your feet together) try jumping rope

Your body had not build up its endurance yet.  However, make sure you're eating enough to take place of the calories that you're using up when running.  The more you work out, the more calories you need to give you energy to finish your regular day.

This depends on the sport- Aerobic conditioning sports such as distance running can stimulate mitochondrial generation-but only at a fairly high level of conditioning.  Baseball, weightlifting, etc, would likely not stress the aerobic system enough.  Prior to more mitochondria being generated, there are changes which increase the efficiency of oxygen usage, increased density of capillary beds, increased storage of glycogen and creatine for anaerobic metabolist, etc.  Increased numbers of mitochondria is a minor effect compared to those listed.

no, unless you can swim in carbon dioxide gas

Back when I was working out and running every morning for two months (before breakfast), by the end of those two months, my energy level was through the roof.  I actually had the energy to clean the house.\n\nSo exercise is definitely one way to get energized.  It'll take some time though.

The only way to jumpstart your metabolism is to exercise.  You will start building muscle which means you will eventually have to burn more fuel to do the same movements.  Also, your body will actually constuct more capillaries inside of your muscles so that it can get fuel there more quickly.

It's your body trying to absorb more oxygen into your bloodstream, allowing for more energy.

oversleeping causes carbon dioxide poisoning - do exercise, it would probably help.

I think it is a real thing.  I know when I am running or exercising there are times when I am dragging, but once I get going things get better.  This is beyond any normal warm up period.  It may be more psychological than physical, but I do believe you can get a second wind...

Maybe if you sat in front of it all day. You wouldn`t sweat as much which is part of what causes you to lose weight when you exercise. So I could see it MAYBE contributing in some very small way. I wouldn`t TOTALLY disregard it.  Good question by the way :o)

I think if you eat something small like a granola bar or something, so you at least have some fuel (energy) to use when exercising, it is ok. I heard that if you do that, have a good work out, and then eat, it's actually better because after working out your metabolism is going fast & is ready to burn off what you eat next. I don't know if that's totally accurate, but it is what I have heard.

CO2 is a bi-product of combustion and as your body is a reactor producing a lot of CO2, levels rise very quickly during exercise.  \n\nCO2 is our primary stimulus to breath.  Lack of O2 is our secondary stimulus to breath.  Smokers who have chronic lung problems have worn out their primary stimulus because their CO2 levels are very high all of the time.  They rely completely on a lack of oxygen to continue breathing spontaneously.  If they are given high doses of Oxygen in a mask, they can stop breathing completely in their sleep.\n\nCO2 in the blood stream makes carbonic acid so the smoker, above, has blood acidosis.  \n\nAcidosis of the blood stimulates breathing and the more co2 you have in your blood (ie: exercise) the harder and faster you breath.  When the co2 level normalizes in a healthy person, breathing slows to a normal rate.\n\nIf you continue to breath hard and fast after normalization, like if you're scared and are hyperventilating, you will develop blood alkalosis which is too little co2 in your blood.  That's when your lips get numb and you don't think so good.\n\nSo, co2 is a byproduct of exercise which causes increase in co2 in the blood which stimulates you to breath harder.\n\nbreathing regulates co2 levels in healthy humans.\n\nHope this helps

Carbon dioxide acts as a greenhouse gas at all altitudes. You are correct that it is heavier than air, and therefore is less prevalent at higher altitudes.

It slows down your pulse rate.  Since you are doing less activity your body will require less active energy - in the form of ATP.  Oxygen (supplied by the blood) is necessary for aerobic respiration - the Krebs Cycle.  Aerobic respiration contributes 32-38 ATP per 1 mol of glucose, whereas anaerobic contributes 2 ATP per 1 mol of glucose.  So since your muscles aren't readily using vast amounts of ATP, you don't need to produce as much.  However, if you start to run, for example, and you feel your muscles start to burn - build up of lactic acid which blocks acetylcholine (neurotransmitter necessary for muscle contration) and changes the structure of proteins- you will notice that you will start to breathe faster.  You breathe faster in order to increase the amount of oxygen in your blood to wash out the lactic acid which will be converted into glycogen.  To sum up, using a lot of energy requires more oxygen leading to a faster pulse.  Not using a lot of energy - slower pulse.

CO2 is the byproduct as it is given out after energy is taken by burning the food in the tissues .energy is not the byproduct of respiration.it is the ultimate product due to which we get energy to sit in frnt of the computer.lol(xcuse the bad pun)
