Use the following to answer the questions below: Below are descriptions of the variables needed to plot a graph on which enzyme activity is the y- axis. For each description choose from the response list the "shape" of the resulting graph. Choices may be used more than once or need not be used at all. a) line with an upward slope b) line with a downward slope c) line with an upward slope and a long flat top d) line with an upward slope followed by a downward slope Increase in enzyme concentration with all other variables constant

"Protein" Or "No protein present" in the following foods

Chemistry I need help understanding these questions more. Incorrect Question 11 A protein with polar sidechains on the outside of the main area and non-polar sidechains on the outside of a short tail is likely located where? Free floating in the blood Fully encased in the cell wall Anchored to the cell wall and mostly outside the wall Anchored to the cell wall and mostly inside the wall Question 9 Which description(s) below could belong to a steroid? multicyclic molecule often acts as a signal in the body used as an energy source Diverse function beyond societal stereotypes Question 8 Which molecule(s) contain lots of nitrogens in rings? Amylose DNA Proteins RNA Lipids Partial tial

Question 6 The hydropathy of amino acids can help determine the folding of protein chains. True False Moving to the next question prevents changes to this answer.

A student is testing for the presence of protein, simple sugars, starch, and lipids using the tests summarized in the table below.  Molecule Test Positive Result Negative Result Protein Biuret reagent Pink or purple Blue Simple sugars Benedict's reagent Green, Orange or Red Blue Starch Iodine Orange, Blue or Purple Yellow Lipids Brown paper Oily Stain No stain   The student tests an unknown solution using each of the tests and observes that the solution turns blue-black when he tests for protein. Which of the following conclusions can the student make? A. The solution contains carbohydrates. B. The solution contains lipids. C. No conclusion can be drawn; the student made an error. D. The solution contains starch. E. The solution contains protein.

Select the correct statements about the isoelectric point of a protein. ( all that may applied ) - the charge on the protein will be neutral. - the pH of the solution will always be greater than 7. - the protein molecules will dissolve into solution. - the pH of the solution will ways be less than 7. - the protein molecules coagulate and precipitate from solution - the number of positive charges on the protein will be equal to the number of negative charges. - the pH of the solution will always be exactly 7.

A Moving to another question will save this response. Question 23 The type of enzyme that catalyzes a reduction is known as a(n). A Moving to another question will save this response.

Find an example of an enzyme. a) What is the chemical reaction that is catalyzed by the enzyme? b) Why is this enzyme/chemical reaction important to the organisms in which it occurs?

Erwin Smith wants to determine the average concentration of amino acids present in the spinal fluid of Eldians. He assigned four people to complete this task. Who among these four people will be able to obtain the best results?   a.Levi Ackerman, who obtained samples from 100 Eldians from Wall Maria   b.Mikasa Ackerman, who obtained samples from 100 Eldians from Wall Rose   c.Hange Zoe, who obtained samples from 50 Eldians inside Wall Sina and 50 Eldians from Wall Rose   d.Armin Arlert, who obtained samples from 34 Eldians from Wall Maria, 33 Eldians from Wall Rose, and 33 Eldians from Wall Sina
