One of the effects of the hormone secretin is to stimulate the release of bicarbonate ions into the duodenum, which neutralizes the acid that enters the duodenum with food from the stomach. one consequence of neutralizing the ph in the intestine is that: the enzymatically catalyzed hydrolysis of carbohydrate that began in the stomach is halted in the duodenum. enzymes that catalyze the hydrolysis of carbohydrates are denatured. enzymes that catalyze the hydrolysis of carbohydrates are active. carbohydrates are not as easily broken down in this neutral environment.

enzymes that catalyze the hydrolysis of carbohydrates are active.

Explanation:

The pH within the small intestine should be neutral so that enzymes that break down macromolecules can work properly (unlike in stomach where the enzymes require acid pH). Small intestine is part of the digestive system, in which proteins, lipids and carbohydrates are hydrolyzed. Carbohydrate digestion in small intestine is performed by pancreatic enzyme amylase, maltase, sucrase, and lactase (secreted by the small intestine). Neutral environment is suitable environment for those enzymes.

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.
