Predict how glycogen AND glucose metabolism would change in an individual afflicted with a deficiency in the glycogen branching enzyme, and explain why.
define metabolism and enzyme. provide 2 examples of enzymes and explain how they are important for metabolism. give 2 examples of biomolecules that are not enzymes and define their roles in metabolism
•Describe the basic structure of collagen monomers •Explain how amino acid composition of collagen contributes to structure and Explain how collagen fibrils, fibers and sheets are formed and how that relates to their function.
You had an under-eating day. In other words, you ate fewer calories than you expended. Explain how the body will deal with your caloric short fall. Include in your discussion: the hormones that will influence metabolism; what lipid enzyme is active; and what is happening in the different organs and tissues. Now you had an over eating day. Explain how the body will deal with your caloric excess. Include in your discussion: the hormones that will influence metabolism; what lipid...
7. Explain the basics of enzyme function and structure (sketch an enzyme and label the active site, allosteric site, where the substrate binds, where competitive and non-competitive inhibitors bind). Include how many different reactions can be catalyzed by an enzyme and how many times an enzyme can catalyze that reaction.
Explain how the tri-carboxylic acid cycle connects the metabolism of carbohydrates, amino acids and lipids.
RuBisCO is an enzyme whose function can be related to the state of the stomata. When the stomata are open and photosynthesis is active, RuBisCO ribulose bisphosphate.
Some bacteria make an enzyme called β-galactosidase that catalyzes the breakdown of the polysaccharide β-galactoside into monomers of galactose. A population of bacteria were found with an amino acid mutation within the active site of β-galactosidase protein, and these bacteria were unable to breakdown β-galactoside polymers. A) How would you identify a population of bacteria with mutant β.galac tosidase in terms of the relative concentration of β-galactoside and galactose in their cells? B.) Explain how the amino acid mutation could...
Q 3: You are trying to identify the peroxisome-targeting sequence in the thiolase enzyme in yeast. The thiolase enzyme normally resides in the peroxisome and therefore must contain amino acid sequences that are used to target the enzyme for import into the peroxisome. To identify the targeting sequences, you create a set of hybrid genes that encode fusion proteins containing part of the thiolase protein fused to another protein, histidinol dehydrogenase (HDH). HDH is a cytosolic enzyme required for the...
1. Explain how bioavailability affects the functionality of vitamins within the body. Discuss how food preparation methods affect vitamin bioavailability. 2. Even though vitamins are not considered to be energy-yielding nutrients they play a required role in metabolism. How do they accomplish this task? Identify the significant roles of B complex vitamins in metabolism. 3. Describe a unique source of niacin and a unique function of niacin in the body. 4. Explain the features of folate that are associated with...
