zed in a Varlếty of Peactiðns in the cell. Research đescribe two specific Peactions that IP. of them must be a process involving transport across membranes. The second must be a process involving metabolism, and utilizing an enzyme (name the enzyme). Explain how ATP is used and why it is needed in the two processes described.

We have discussed the aerobic metabolism of glucose extensively in this class. To capture and use the energy in glucose to make ATP, we must utilize 4 different sequential pathways/steps. Starting with one glucose molecule and eventually ending with CO, H;O and ATP, list the 4 pathways/steps in order and tell me what molecules enter each pathway, and what the final products of each pathway are.

In an experiemnt with various temperatures (4°C, 22°C, 50°C and 70°C) to examine how temperature impacts peroxidase activity. State the null hypothesis and alternative hypothesis for this experiment. (Enzyme works best at 50°C)    2. Draw a graph showing relationship of absorbance over time in three cuvettes, (a) one with high amounts of enzyme, (b) one with low amounts of enzyme, and (c) one with medium amounts of enzyme. Assume that the amount of substrate is the same in all three, as is the amount of the dye, guaiacol.  Make sure that you have all the components of the graph including axes titles, units of measurement, legends, etc. 3. A group of researchers varied the concentrations of Fe2+ cofactors added in the solution in which a Hydrogen peroxide + peroxidase reaction took place. They added the cofactor at concentrations = 0.5 ml, 0.4 ml, 0.3 ml, 0.2 ml, 0.1 ml.  A. Draw a graph depicting expected results for this experiment. Make sure that all the components of the graph…
