One of the effects of the hormone secretin is to stimulate the release of bicarbonate ions into the duodenum, which neutralizes
Alecsey [184]

Answer: One consequence of neutralizing the pH in the intestine is that ENZYMES THAT CATALYZE THE HYDROLYSIS OF CARBOHYDRATES ARE ACTIVE.

Explanation: During digestion, partially digested food particles are transported from the stomach to the first part of the small intestines, that is, the duodenum. The food particles that are coming from the stomach are acidic due to the secretion of hydrochloric acid in the stomach. This acidity has to be removed when the food particles get into the duodenum, this is because the enzymes that are needed to break down carbohydrates in the duodenum can not work in acidic medium. Thus, in order for the  pancreatic amlayse enzyme to become active and to complete the break down of carbohydrate in the duodenum, the secretin hormone has to stimulate the release of bicarbonate that will neutralize the acidic partially digested food particles from the stomach.

Consider the following geometric solids a sphere with a ratio of surface area to volume equal to 0.08 M negative one a right cir
azamat

Options:

A. The rate of diffusion would be the same for the two models.

B. The rate of diffusion would be faster for the right cylinder.

C. The rate of diffusion would be slower for the right cylinder.

D. The rate of diffusion would be faster for the sphere.

Answers:

The rate of diffusion would be faster for the right cylinder. Thus, the correct option is B.

To begin with, we must comprehend how the ratio of surface area to volume affects the rate of diffusion.

When comparing the ratio of surface area to volume, a body with a larger surface area will have a higher rate of diffusion than a body with a smaller surface area. It can be expressed mathematically as:

V∝ R    (whereas v is the diffusion rate and r is the surface area to volume ratio)

The answer to the question's surface area to volume ratio for spheres is given 0.8m⁻1

For a right circular cylinder, the surface area to volume ratio is provided  is 2.1 M.

The right circular cylinder has a larger ratio, hence it is obvious that the right circular cylinder will have a higher rate of diffusion because the rate of diffusion is directly related to the surface area to volume ratio.
