Question we're being asked to relate exercise to the increased rate of respiration or the increased amount of breaths.
00:15
So here we can first start by looking at exercise.
00:19
This is going to correspond to aerobic and anaerobic respiration, which i'll abbreviate as an o2 and a.
00:29
There are several products of each of these processes, which is going to be an increased amount of co2, you're going to generate heat from the movement of muscles, and you're going to generate protons.
00:47
Protons are going to be generated from your anaerobic respiration in the form of a molecule called lactic acid.
00:55
Because it's an acid, this just means you're going to have the production of a proton that can be released from the molecule.
01:04
And of course, an increased number of hydrogens is going to correspond to a decrease in ph.
01:13
Also for this question, it's important to relate the increased amount of co2 in part of the respiration cycle.
01:22
So here, respiration and the conversion of co2 involves a molecule called carbonic anhydrase, which is going to convert co2 and h -sycure.
01:33
Into a molecule called h2c03.
01:37
And this is then converted into a proton and a bicarbonate ion.
01:48
So your body undergoes this process because bicarbonate is easier to dissolve in the plasma as opposed to co2...
