| Tóm tắt: | All living organisms on Earth are slaves
to environmental temperature change.
Temperature rules the fundamental bio-
chemistry of cellular metabolism -
temperature change alters the rates of all
metabolic reactions and changes the
conformations of all macromolecules.
Temperature also constrains the lives of
most organisms - for example, temperature
change affects all aquatic organisms by
altering the solubility of oxygen in water,
tissue freezing at temperatures below 0°C is
lethal to the vast majority of organisms, and
sustained high temperatures above about
50°C are also lethal to most. Organisms can
use biochemical, physiological or behavioural
adaptations to help them cope with
temperature variation, within limits, and
these have been explored in depth by
hundreds of researchers (Hochachka and
Somero, 1984; Willmer et al., 2005; Rao et
al., 2006). Most organisms on Earth are
ectotherms, having limited or no control
over their temperature. We humans are
`luckier' than most in being among the small
percentage of species on Earth that are
endotherms, having internal control over
body temperature. |
