?-Galactosidase (?-gal) is a hydrolase enzyme that catalyzes thehydrolysis of ?-galactosides into monosaccharides. A 0.678 gramsample of ?-galactosidase is dissolved in water to make 0.173 L ofsolution, and the osmotic pressure of the solution at 25

Immunoglobulin G(IgG), formerly called gammaglobulin, is a principle antibody in blood serum. A 1.00 gramsample of immunoglobulin G is dissolved in water to make 0.198 L ofsolution, and the osmotic pressure of the solution at 25C is foundto be 0.837 mbar. Calculate the molecular mass of immunoglobulinG.

?-Galactosidase (?-gal) is a hydrolase enzyme that catalyzes thehydrolysis of ?-galactosides into monosaccharides. A 0.411 gramsample of ?-galactosidase is dissolved in water to make 0.145 L ofsolution, and the osmotic pressure of the solution at 25

Beano contains an enzyme that breaks down polysaccharides into smaller, more digestible sugars, which diminishes the intestinal gas formation that can occur after eating foods such as vegetables and beans. (20.1, 20.2, 20.5) a. The label says “contains alpha-galactosidase.” What class of enzyme is this? b. What is the substrate for the enzyme? c. The directions indicate you should not cook with or heat Beano. Why?

Compare and contrast the structural and chemical compositions ofthe Gram-negative vs. Gram-positive baterial cell walls. Why arethese cell walls differentiated by the Gram stain? Please limityour response to a paragraph or two.

Question:

Bacteria are classified as Gram positive and Gram negative on the basis of the polysaccharide (primarily peptidoglycan) content of their cell walls. Explain the difference between the two types based on Gram staining character? Please note that Gram positive appear purple and Gram negative appear pink on microscopic examination is not an answer. Your answer must include a suitable explanation at the molecular level with reference to bacterial cell wall composition.

Explain the structural and functional advantages of quaternary association with reference to proteins? Your answer must include the definition of quaternary structure, at least two examples of proteins exhibiting quaternary structure, and at least three advantages of quaternary association.

A) Explaining the difference in Gram staining character supported by a suitable explanation at the molecular level with reference to bacterial cell wall composition (4 points); an appropriate example of Gram positive and Gram negative bacteria (0.5 points each). B) Definition of quaternary structure (1 point); two examples of proteins exhibiting quaternary structure (0.5 points each); three advantages of quaternary association (3 points).

PLEASE READ THE QUESTIONS CAREFULLY BEFORE ANSWERING (MICROBIOLOGY ) THANK YOU!

Some photosynthetic cyanobacteria carry out nitrogen fixation in specialized compartments that contain photosystem I, but lack photosystem II. Use one sentence to explain why it would be advantageous to separate nitrogen fixation from photosystem II.

What would you say to someone who did a presentation about understanding the world through research and analysis to create harmony and a better future for humanity?

A box of canned goods slides down a ramp from street level into the basement of a grocery store with acceleration 0.62 m/s2 directed down the ramp. The ramp makes an angle of 40° with the horizontal. What is the coefficient of kinetic friction between the box and the ramp?

Two masses of 4.50 kg each, connected by a string, slide down a ramp making an angle of 40 degrees with the horizontal. The coefficient of kinetic friction between M1 and the ramp is 0.34. The coefficient of kinetic friction between M2 and the ramp is 0.18. Find the magnitude of the acceleration of the masses.
