Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

Expert Solution & Answer

Answer to Problem 1E

Correct answer

The correct answer is option (c).

Explanation of Solution

Explanation for the correct answer

Option (c) is given as they are transported into capillaries in the villi. The food is digested into simpler nutrients in the digestive system. Sodium, fatty acids and vitamin A are absorbed in the small intestine. The walls of small intestine contain hair like outgrowths called villi that increase the surface area to facilitate absorption of these nutrients. Hence, the correct answer is option (c).

Explanation for the incorrect options

Option (a) is given as they are not enzymatically modified prior to their absorption into the blood stream. Vitamin A does not undergo any transformation before absorption. Hence, option (a) is incorrect.

Option (b) is given as they cross the apical membrane of enterocytes by simple diffusion. The transport of sodium requires sodium/potassium ion channels and special membrane proteins or channels are required for the active transport of vitamin A. Hence, option (b) is incorrect.

Option (d) is given as they are all hydrophilic. Fatty acids do no interact with water and are therefore, hydrophobic. Same is true for vitamin A. It is fat soluble and does not interact with water. Hence, option (d) is incorrect.

Option (e) is given as All the above. Since, options (a), (b) and (d) are incorrect, option (e) is also wrong.

Conclusion

Fatty acids, vitamin A and sodium are absorbed in the small intestine through hair like outgrowths known as villi, which increases the surface area of the intestine for the sole purpose of absorption.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2

There is currently a H5N1 cattle outbreak in North America. According to the CDC on Feb 26*: "A multistate outbreak of HPAI A(H5N1) bird flu in dairy cows was first reported on March 25, 2024. This is the first time that these bird flu viruses had been found in cows. In the United States, since 2022, USDA has reported HPAI A(H5N1) virus detections in more than 200 mammals." List and describe two mechanisms that could lead to this H5N1 influenza strain evolving to spread in human: Mechanisms 1: Mechanisms 2: For the mutations to results in a human epidered they would need to change how the virus interacts with the human host. In the case of mutations that may promote an epidemic, provide an example for: a protein that might incur a mutation: how the mutation would change interactions with cells in the respiratory tract (name the receptor on human cells) List two phenotypic consequence from this mutation that would increase human risk

You have a bacterial strain with the CMU operon: a) As shown in the image below, the cmu operon encodes a peptide (Pep1), as well as a kinase and regulator corresponding to a two-component system. The cmu operon is activated when Pep 1 is added to the growth media. Pep1 is a peptide that when added extracellularly leads to activation of the Cmu operon. Pep1 cmu-kinase cmu-regulator You also have these genetic components in other strains: b) An alternative sigma factor, with a promoter activated by the cmu-regulator, that control a series of multiple operons that together encode a transformasome (cellular machinery for transformation). c) the gene cl (a repressor). d) the promoter X, which includes a cl binding site (and in the absence of cl is active). e) the gene gp (encoding a green fluorescence protein).
