Q10 is a measure of temperature sensitivity

Even within the range from 0° to 45°C, changes in tissue temperature create problems for animals. Most physiological processes, like the biochemical reactions that constitute them, are temperature-sensitive, going faster at higher temperatures (see Figure 6.23). The temperature sensitivity of a reaction or process can be described in terms of Q10, a quotient calculated by dividing the rate of a process or reaction at a certain temperature, RT, by the rate of that process or reaction at a temperature 10°C lower, RT-10:

rt rt

Q10 can be measured for a simple enzymatic reaction or for a complex physiological process, such as rate of oxygen consumption. If a reaction or process is not temperature-

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
