Each enzyme functions in a different area of the body, but both work to harness the power in carbohydrates and break these complex molecules into simple sugars. Based on the information you have learned about the digestive system, what do you expect to be the optimal pH for the enzymatic action of pancreatic amylase?

Answers

Answer 1

Answer: The optimal pH is 6.9. The pancreatic amylase is a hydrolase secreted by the pancreas and will go into the alimentary canal. The working environment has a pH of 6.9. So the optimal pH for the enzyme needs to be 6.9.

Explanation:

The optimum pH scale for the catalyst activity of secretion enzyme ranges from half-dozen to seven. higher than and below this vary, the reaction rate reduces as enzymes get denaturated. The accelerator secretion enzyme is most active at pH scale 6.8.
Human duct gland alpha-amylase. II. Effects of hydrogen ion concentration, substrate and ions on the activity of the protein. refined human duct gland alpha-amylase (alpha-1,4-glucan 4-glucanohydrolase, EC 3.2.1.1) was found to be stable over a large vary of hydrogen ion concentration values (5.0 to 10.5.

Answer 2

Answer: The optimal pH is 6.9. The pancreatic amylase is a hydrolase secreted by pancreas and will go into the alimentary canal. The working environment has a pH of 6.9. So the optimal pH for the enzyme needs to be 6.9.

Which structural formula represents 1,1 dibromopropane

Answers

The structural formula of 1, 1 dibromo propane is C₃H₆Br₂.

What is dibromopropane?

It is an organobromine compound. It is a colorless liquid. It is fpmed by the reaction of allyl bromide and hydrogen bromide.

It is used in organic synthesis of compounds.

Thus, the structural formula of 1, 1 dibromo propane is C₃H₆Br₂.

What is c2h5oh and the difference between it and c2h6o

Answers

-Physical condition: C₂H₅OH is liquid; CH₃OCH₃ is a gas.
-Reactivity: C₂H₅ reacts with sodium (Na) metallic, releasing H₂ and forming the sodium ethoxide, Na (+) C₂H₅-O (-) (C₂H₅ONa).CH₃OCH₃ no reacts with sodium.-water solubility: C₂H₅OH dissolves in any proportionCH₃OCH₃ is poorly soluble in H₂O.
-polarity: C₂H₅OH is very polar, form hydrogen bonds.CH₃OCH₃ is little polar, doesn't have H available to form hydrogen bridge.
Write C₂H₆O may cause ambiguity because there are 2 different substances with this formula:-ethyl alcohol or ethanol = CH₃---CH₂---H
methyl ether = CH₃---O---CH₃

If you label a bottle only with C₂H₆O, will be very difficult to know if the compound is methyl ether or ethanol, which can be very dangerous in the laboratory. As only the ethanol C₂H₅OH is structured, it is convenient to use preferably this formula. For the methyl ether, it is more efficient to use the formula CH₃OCH₃.

20. The light intensity of a source is 100 candelas. The illuminance on a surface is 4 lux. How far is the surface from the source?
A. 4 meters
B. 6 meters
C. 5 meters
D. 7 meters
Student Answer: B
Answer: Incorrect

Answers

The answer to question 2 is C. A magnifying glass is an example of a plano-convex lens, where one side of the lens is flat and the other is a convex curve. The answer to question 3 is either B or C. A converging lens is curved on both sides and so the rays of light coming out of it converge at a point, which is known as the focal point. When the object is inside the focal point, the image is real and inverted. If it is inside the focal point, the image is virtual and upright. Therefore the image in this question will be upright. The focal length is the distance between the image that is being magnified and the centre of the magnifying lens. A real image can only be formed when the object is further away from the lens than the focal length. Therefore, in this question, the image is virtual, as the object is closer to the lens than the focal length. The answer to question 4 is D because the index of refraction cannot be less than 1. The answer to question 5 is D because only concave mirrors can produce real images; other types produce virtual images. For question 6, the answer is D. In the rainbow, each of the colours refracts at a slightly different angle; red has the smallest refractive index and violet the largest. Of the options, orange is closest to red. For question 12, A is the answer. A higher operating temperature is not a reason fluorescent lamps are better than incandescent lamps because they have a lower operating temperature. Question 15: all of these are characteristics of different electromagetic waves. For question 18, B is true - special care must be taken when low illuminance is required to reduce glare. The answer to question 19 is B - a compound microscope makes use of two lenses. For question 20, the answer is 5 meters away. The illuminance (E) is equal to light intensity (I) divided by the square distance from the light source (d). Therefore, 4 = 100/d squared. To switch this around, d squared is equal to 100/4 = 25. Then find the square root of 25, which is 5.

How to convert Gdm-3 to moldm-3

Answers

Since it is still in dm^-3 (which is basically a Litre)

You just need to convert the g into moles using the formula:

moles = mass/molar mass

= 5.6/(39.1+16+1)

= 5.6/56.1

= 0.1 moles

So this makes it 0.1 moles dm^-3
