Answer to Problem 1RQ

Correct Answer:

a. Chyme is produced here	2.stomach
b. Organ where most digestion occurs	3.small intestine
c. Initial section of small intestine	4.duodenum
d. This adds exocrine secretions to duodenum via a duct	7.pancreas, 10.liver
e. Sphincter between stomach and intestine	8.pylorus
f. Enzymes produced here	2.stomach, 3.Small intestine, 7.Pancreas
g. Distension of its walls triggers the defecation reflex	9.rectum

Explanation of Solution

a. Chyme is produced here- 2. stomach

Chyme is mixture of partly digested food and stomach fluids. The food comes through the esophagus and reaches to stomach. The secretions from the digestive glands reach the stomach, and they form a mixture called chyme.

b. Organ where most digestion occurs- 3. small intestine

The small intestine is the site at which most of the digestion occurs. This is because small intestine provides larger surface area due to the presence of villi.

c. Initial section of small intestine- 4. duodenum

The small intestine is divided into three sections, namely duodenum, jejunum, and ileum. The duodenum is the initial section of the small intestine.

d. This adds exocrine secretions to duodenum via a duct- 7. Pancreas and 10. liver

Pancreas and liver are two accessory glandular organs. The pancreas secretes pancreatic juices and the liver secretes bile. Their secretions enter into the duodenum via ducts.

e. Sphincter between stomach and intestine- 8. pylorus

The pylorus is present between the stomach and small intestine; it acts as a gatekeeper. The movement of the pylorus is guarded by the pyloric valve. The valve is a thickened band of smooth muscle.

f. Enzymes produced here- 2. stomach, 3. small intestine, 7. pancreas

Enzymes are the proteins that break food into an absorbable form. The stomach produces two enzymes, gastric lipase and pepsinogen. The small intestine produces two enzymes, maltase, and peptidases. The pancreas produces proteolytic enzymes such as trypsin and chymotrypsin.

g. Distension of its walls triggers the defecation reflex- 9. rectum

The rectum is the end part of the large intestine that stores undigested food for some time. When the volume reaches up to the level, the defecation reflex occurs. This removes the undigested food from the body in the form of feces.

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
