pH and temperature
light intensity and humidity
pH and enzyme concentration
salt concentration and temperature
Which of the following graphs represents the effect of pH on the rate of reaction by trypsin?
Graph in figure shows the effects of temperature on the rate of an enzyme- catalysed-reaction. Which of the following statement is correct?
When the temperatures is low, the enzyme-catalyzed reaction is high.
When the temperatures is high, the rate of reaction is not accelerated.
When the temperatures is optimum, the enzyme catalyses the reaction at the maximum rate.
When the temperatures is beyond the optimum, the enzyme catalyses the reaction is increase
Table shows the result obtained from the experiment to investigate the temperature on the activity of amylase.What inference can be made from the above observations?
In test tube Q, rate of reaction is decreasing.
In test tube R, rate of reaction is optimum
In test tube S, rate of reaction is increasing
In test tube T, rate of reaction is accelerated
Figure shows the relationship between the rate of reaction and substrate concentration.
When the concentration of substrate increase more product is produced because more subtrate molecules are available to bind the active sites of the enzymes
The rate of reaction increases because there are less chances of collisions between the substrate molecules and the enzymes molecules
When the substrate concentration increases, the speed of reaction also increases because less substrate binds the active of the enzymes
The rate of reaction is directly proportional the substrate concentrate continuously without limiting factor.
Which enzyme works best at pH 1.5 - 2.5?
Lipase
Pepsin
Trypsin
Amylase
