Drawing upon the resources and concepts covered in the Metabolism lab, and supplementing with some external research, complete the following:1. Identify which specific tests in the Metabolism lab were used to: a. determine the presence of amylase, and b. determine the presence of maltose.2. Consider the list of alternative techniques provided below. Select two alternative techniques from the list: one that would be appropriate for directly identifying amylase and one that would be appropriate for directly identifying maltose. You MUST select two different techniques, one for each molecule.3. Compare and contrast your selected alternative techniques with the test(s) used in the Metabolism lab. Identify and describe at least one advantage and one disadvantage of the alternative technique when compared to the test(s) used in the Metabolism experiment (advantage = 50 words, disadvantage = 50 words).4. Based on your comparison above, justify which of the two techniques (original or alternative) you would recommend for future use in this experiment (50 words).Note 1: If more than two techniques are provided, only the first two will be considered and marked.Note 2: If the same technique is used for both amylase and maltose, only the first instance will be marked. The second instance will receive zero marks.Note 3: Answers using alternative techniques that are not on the list provided below will not be considered. These answers will receive zero marks.Alternative Laboratory Techniques:
- Gel electrophoresis
- Barfoed test
- Protein sequencing
- Polymerase chain reaction (PCR)
- Molisch's test
- Fehling's test
- High performance liquid chromatography (HPLC)
- Mass spectrometry
- Bial's test
- Southern blot
- Enzyme-linked immunosorbent assay (ELISA)
Complete the following by selecting the most accurate statements from each drop down menu.In dormant seeds, the embryo
Use the data in the table below to answer the following questions.
| Seed Stage | Mass (g) | Achromic Point (mins) | Volume (mL) |
| Dormant | 1.23 | 20-NAP | 9.34 |
| Germinating | 1.03 | 12.00 | 9.77 |
| Seedlings | 2.25 | 8.00 | 9.80 |
Based on the experimental protocols and the data provided in the table above, fill in the boxes below to show your calculation of the amylase activity for germinating seeds. Enter numerical values only and give your answer to two decimal places.Amylase activity = ( / ) / ( / / )Final amylase activity = What are the units that should be used for amylase activity?
A manufacturer is formulating a new enzyme-based biologically active detergent (BAD) and wants to claim that it is able to effectively remove food stains from clothing during washing. The images below are from lab tests using BAD to determine if there is scientific evidence that can support their claims. Please review these results:
A student prepares an amylase extract from a sample of seeds and dilutes it fivefold. They add 1 mL of this diluted amylase extract to a tube containing the reaction mixture. They then immediately add one drop of this reaction mixture to a drop plate containing iodine, and notice that at time 0, an achromic point has already been reached.What is the most likely explanation for this result?
The results of the catalase test in this lab indicates that:Select all that apply. Marks are deducted for incorrect answers.
A student prepares a sample of amylase extract. The seed mass is 0.87 g and the volume is 4.89 mL. The student sets up an achromic test and an achromic point is reached within 4 minutes. This sample is then added to a Benedict's test.What do you expect the Benedict's test results to show in each of the experimental and control tubes?Experimental tube:
Answer this question based on what you did in this particular lab.It is expected that the boiled control
In cells, exergonic and endergonic reactions play crucial roles in metabolism and energy management. Amylase is a protein synthesized from amino acids. Which of the following statements correctly describes the formation of amylase from amino acids?
