Segment 1 Dr Thorn describes how our respiration changes when we exercise and shows the results of polarographic readouts detailing changes in respiration during exercise. Time start: 00:00:00:00 Time end: 00:05:11:13 Length: 00:05:11:13
Segment 2 Thorn refers to studies done into the relationship between mitochondria and respiration. Time start: 00:05:11:13 Time end: 00:09:11:22 Length: 00:04:00:09
Segment 3 Thorn shows further experiments using polarographic readings and describes in detail how changes in oxygen molecules can be observed during exercise. Time start: 00:09:11:22 Time end: 00:15:41:00 Length: 00:06:29:03
Segment 4 Further polarographic studies are shown, this time detailing an experiment in which a mitochondrial suspension is added to cells and respiration rates measured. Time start: 00:15:41:00 Time end: 00:20:29:00 Length: 00:04:48:00
Segment 5 Thorn shows the results of two further experiments concering interference treatments on the enzyme system. Again, he refers to readings from a polarograph. Time start: 00:20:29:00 Time end: 00:24:09:00 Length: 00:03:40:00
Segment 6 Thorn ends with the results of a final experiment showing how motochondria, which have been subjected to hypotonic conditions at room temperature, respire. Time start: 00:24:09:00 Time end: 00:30:30:10 Length: 00:06:21:10
