As Brandon climbs the mountain, he is getting into thinner and thinner air (air pressure is decreasing). All other things held constant, decreasing air pressure means decreasing temperature. As the air pressure decreases, particles get further apart and lose energy as they move about and collide into one another less and less frequently.
Protein denaturation results in a disruption
of the secondary and tertiary structure.
A denatured protein does not have the function it previously had. Some
proteins owe their functions to the three dimensional shape they have; what is
responsible for holding the shape of a protein is the R-group interactions.
