37 degrees Celsius
water temperature
Amylase has an optimal pH range of 6.7 - 7.0 and an optimal temperature of around 37 degrees Celsius or 98.6 degrees Fahrenheit. This is what would be expected of an enzyme that needs to be in its most active form in the saliva of the mouth.
Amylase enzymes.
works best in neutral conditions
Amylase is an enzyme, which is a type of protein. Protein denatures when temperature or pH (acidity) is changed. for example, amylase will no longer digest starch if you put it in a boiling water bath for 5 minutes. in the stomach, hydrochloric acid is produced by the stomach lining to digest food. this acid will denature the amylase when the swallowed food mixed with amylase from the mouth enters the stomach.
Amylase works best at body temperature, which is around 37 degrees Celsius. This is because if the temperatre is too low, the amylase will collide slow as the kinetic energy will be low. It reacts fastest and best in this temperatue as lota of kinetic energy is given to the molecules and the particles therefore collide faster. Although, when the temperature is too high, the enzymes (amylase) gets denatured which means that they loose their shape. This way they do not react.
yes it does
Enzymes from an organism are generally going to work best around the conditions that the organism tends to live. Fungi usually live in quite cool areas (think woodland) and in acidic soils. Bacteria can live anywhere generally and their optimum conditions could be anything.
Nothing special.
investigate the relationship between reaction temperature and the effectiveness of the Enzyme amalayse on starch
Two degrees.
38 deg C
identify two pH values at which salivary amylase activity stop?
The enzyme that acts on starch is Amylase, and conveniently this is found in the saliva. By looking at Amylase efficiency curves, it becomes clear that amylase works more efficiently at 40 C. Therefore, the answer is 40 C.
