Which enzyme is produced by the stomach? Pepsin Insulin Secretin Chymotrypsin Trypsin

Solution

The answer is the first one: Pepsin.

Explanation for each option:

Pepsin: This is the correct answer. Pepsin is an enzyme produced by the stomach. It is secreted in an inactive form called pepsinogen, which is then activated by the acidic environment of the stomach to become pepsin. Pepsin plays a crucial role in digesting proteins by breaking them down into smaller peptides.
Insulin: This is incorrect. Insulin is a hormone produced by the pancreas, not the stomach. It helps regulate blood glucose levels.
Secretin: This is incorrect. Secretin is a hormone produced by the small intestine, not an enzyme produced by the stomach. It stimulates the pancreas to release bicarbonate to neutralize stomach acid in the small intestine.
Chymotrypsin: This is incorrect. Chymotrypsin is an enzyme produced by the pancreas and released into the small intestine, where it helps digest proteins.
Trypsin: This is incorrect. Trypsin is also an enzyme produced by the pancreas and released into the small intestine, where it aids in protein digestion.

In summary, the enzyme produced by the stomach is pepsin.

Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight? Use a significance level of α=0.05. Determine the null and alternative hypotheses. H0: p=□ H1: ρ> Identify the correlation coefficient, r. r= □ Identify the critical value(s). A. There are two critical values at r= ± □ B. There is one critical value at r= □ Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? Choose the correct answer below and, if necessary, fill in the answer box within your choice. A. Yes, because the correlation coefficient □ falls outside the critical value(s). B. No, because the correlation coefficient □ falls outside the critical value(s). C. No, because the correlation coefficient □ falls between the critical values. D. Yes, because the correlation coefficient □ falls between the critical values. E. The answer cannot be determined from the given information. When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight? A. Yes, it is easier to measure a chest size than a weight because measuring weight would require lifting the bear onto the scale. The chest size could not be used to predict weight because there is not a linear correlation between the two. B. Yes, it is easier to measure a chest size than a weight because measuring weight would require lifting the bear onto the scale. The chest size could be used to predict weight because there is a linear correlation between the two. C. No, it is easier to measure weight than chest size because the chest is not a flat surface. D. Yes, it is easier to measure a chest size than a weight because measuring weight would require lifting the bear onto the scale. The chest size could not be used to predict weight because there is too much variance in the weight of the bears.
