Suppose your biking partner claims that hyperventilating at the bottom of steep hill climbs is a good idea because it will "increase the O2 saturation of the blood" and thereby provide "more O2 for leg muscles during the climb." Hyperventilation reduces the CO2 content of blood. a. Given this fact, is hyperventilation likely to increase O2 delivery to muscles (as your biking partner claims) or not?

No, hyperventilating will not  increase oxygen delivery to the muscle due to decreased concentration of Carbon dioxide in blood..

Explanation:

The reduction of carbon dioxide in the blood will change destabilize tense state of the hemoglobin into relaxed state.

As a result, the p50 value of hemoglobin reduces and the release of oxygen from hemoglobin is hindered.

Thus the oxygen delivery to the muscles will not be increased.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

your answer should be c) enjoy!
