Homework Answers
8.
a. Optimum ph refers to the most favourable ph value which means ,
ph at which the enzyme is most active.
so for catalase enzyme it is 7.0
b. Below the ph 3.0 catalase shows acid denaturation.
so at ph 2.0 acid denaturation will occur.
c. In most of the reactions the concentration of ph will
decrease with time and concetration has direct influence on the
enzyme activity .
so we can conclude that " the rate of reaction will decrease as
enzyme concentration decreases ".

5. Draw a set of coordinate axes on a piece of graph paper. Label the x axis“Output” (0 to 20 units) and the y axis “Cost” (0 to 20 units). Plot the following (x, y) points on your graph: (0, 4); (2, 6); (4, 7); (7, 8); (9, 9); (11, 11); (13, 14). Connect these points with a smooth curve and label it “Total Cost.” Working from this curve, construct a total fixed cost curve and total variable cost curve...

Plot the data for the measurements given below. Being able to create graphs and interpret graphs is an integral part of any science course. You can use the graph paper included in this document, an Excel spreadsheet or your own graph paper. The time measurements are the x-axis coordinates. The temperature measurements are the y-axis coordinates. Space your axes in consecutive intervals such as units of 1,5 or 10. Make sure to label your axes with the appropriate information, including...

Can you draw a bar graph using the data below ake a graph of the
results. A bar graph may be used here, because we were looking at
how carbon dioxide production (dependent variable) varies with
temperature, pH, enzyme concentration (amount of yeast), and
substrate concentraion (independent) and we have 3 discrete values
for each independent variable that we used. You should have four
sets of three different bars on your graph. Be sure to include a
title, labeled axis...
