How does ph of intestine and temperature of the body affect enzyme activity

effect of temperature on lactase enzyme activity

The BBM preparations were isolated from intestine of a healthy human kidney donor subject according to Schmitz et al. Explain how increasing amount of sucrose in food affects sucrase activity.

How would a slight fever affect sucrase activity? Restate your predictions that were not correct and correct them, giving the data from your experiment that supports the corrections.

compare optimal temperature for sucrase activity to body

By virtue of the striking structural homologies between SI and MGAM and the similar biosynthetic pathways [ 5 ] it can be assumed that MGAM is also trafficked to the apical membrane via similar sorting mechanisms.

Pepsin uses the carboxylic acid group on one of its amino acids to break the chemical bond between nitrogen and oxygen in the proteins found in food. Surface area Chewing breaks the large into the small.

how does temperature affect enzyme activity

Additionally, sucrase, isomaltase, maltase and lactase activities were measured in unsolubilized BBM samples and the specific activities for these activities were determined based on the BBM content of the corresponding enzyme s. The supporting details are generally complete and show some synthesis of information in the discussion of pepsin would not work as well; enzymes have an optimal pH range that they work best in; small intestines…higher pH level because it is basic and the stomach is acidic; so the enzyme leaves it optimal range and won't work as well, if at all.

Supporting details are adequate for the student's predictions of how the activity of pepsin will change stop functioning; pH of the small intestine is much higher than that of the stomach and include some use of accurate scientific terminology very acidic; more alkaline.

Effect of ph on enzyme activity experiment

The activity of amylase changes as the pH changes — a higher enzyme activity will result in a faster rate of reaction. In the results section you were asked if rate of increase of sucrase activity was greater when sucrose concentration went from 2. Our data provide a functional measure for characterization of intestinal disaccharidases under different physiological and pathological conditions. These multifunctional disaccharidases are membrane-anchored and heavily N- and O-glycosylated proteins, and are synthesized as single polypeptides at the ER membrane, trafficked along the secretory pathway and sorted onto the apical surface of the epithelial cells with high fidelity [ 4 , 5 , 6 ]. This article has been cited by other articles in PMC. Pepsin Functions at pH 2 The reason pepsin functions best at pH 2 is because the carboxylic acid group on the amino acid in the enzyme's active site must be in its protonated state, meaning bound to a hydrogen atom. Deficiencies in the function of disaccharidases either as a result of genetic mutations or as a consequence of organ pathologies are associated with maldigestion of carbohydrate and gastrointestinal intolerance symptoms such as diarrhea, flatulence and abdominal pain [ 12 ]. The use of accurate scientific terminology catalysts; substrate; denature; activation site; catalyze enhances the response. Although mature LPH associates with a different type of membrane microdomains than those with SI, our data show that the ultimate outcome of such associations in enhancing the functional capacity for both of the disaccharidases is the same. Score Level 1 Anchor Paper This response shows evidence of some understanding of the question. Explain why the rate of increase was greater for this range. Explain how pH of intestine and temperature of body together affect enzyme activity.
