Question: What Does The Ratio Of Drops Of NaOH To Heart Rate Tell You About What’s Going On In The Bodypart B) Should The Ratio (not # Of Drops) Stat Consitent, Increase, Or Decrease As Activity Level Increases? Based In Lab For Metabolism, And How CO2 Is Used And Secrerted. Lab Has Person Doing Exercise Then Blowing Air Into A Mixture Of NaOH And The Color …

CO2 is mostly floating around in the plasma as soluble gas or as H2CO3/HCO, before it is exhaled, but where does it come from and why is it even there? (That’s questions #1 & 2.) Under what conditions will CO, be made, and when won’t it be made (or at least made in lower quantity)? (Be specific about exactly when and where CO2 is made. “During cellular respiration” is going to be way too general an answer, so check out the Metabolism Summary Diagram 1 posted to see when & where the different parts of cellular resniratinn ou 3. In the questions about ratios, remember that a ratio is always a comparison between two things. Ratios look at how one thing changes in relation to the other thing; they are not fractions!** So…. Given your answers to the first two questions regarding CO2, what would you predict would happen to HR during exercise? In this lab the actual numbers calculated are less important than the pattern of ratios as activity levels increased. (A ratio of 0.250 isn’t better than 0.140; they can vary a lot based on muscle mass, lung structure, etc.) Do the ratios stay fairly constant, increase or decrease?
