Wildlife volunteering is a broad topic and there really is something for everyone. Some projects involve really getting your hands dirty in the jungle, but if this does not sound like your thing there are also plenty of other ways to get involved.
EXPERIMENT 2: Recrystallization and Melting Point. Melting Point is: â¢a constant physical property of a solid (the temperature at which it turns to a liquid) â¢reported in the lab as a melting point range (usually 1â2 ËC wide), not as a single temperature.
Temperature. As the temperature rises, reacting molecules have more and more kinetic energy. This increases the chances of a successful collision and so the rate increases. There is a certain temperature at which an enzyme's catalytic activity is at its greatest (see graph).This optimal temperature is usually around human body temperature (37.5 o C) for the enzymes in human cells.See graph) Provided that the substrate concentration is high and that temperature and pH are kept constant, the rate of reaction is proportional to the enzyme concentration. (See graph) Inhibition of enzyme activity Some substances reduce or even stop the catalytic activity of enzymes in biochemical reactions.
