At what pH in the stomach do vegetable proteins from starchy carbohydrates break down?
Pepsin is required for digestion in the stomach O Only proteins O Lipids, carbohydrates, and proteins
Proteins contain the same 3 atoms as carbohydrates, and fat and those 3 atoms are? What does protein contain that carbohydrate and fat do not? Amino means? Proteins are synthesized from building blocks called? There are 20 amino acids in the body; nine are classified as: What is the difference between essential and nonessential amino acids? What is the name of the bond that unites one amino acids to one another? Discuss the difference between hydrolysis and condensation Digestion and...

4.) The enzyme, pepsin, is one that hudrolvess proteins in the stomach, where the pH Is aboun 2 due to stomach acidx, into individual amino acids a) What would you expect to happen so the activity of the enzyme pepsin when in exits the stomach and enters the small imestine where the pi is about ? b.) Amylase is found in saliva where hydrolysis of starches begins. What would you expeet to happen to the activity of the enryme amylase...
Test your knowledge: 1. pH of our stomach is 2. Your stomach produces an enzyme called pepsin which helps with protein digestion. In the stomach the big proteins start to get broken down and form smaller polypeptides. Complete the reaction below to show what is happening? high medium Draw a line to show what you would expect in the accompanying graph. Explain why? 2. low 2 4 pH level 59
Where are each of our macronutrients (carbohydrates, proteins and fats) broken down into components that our cells can absorb? What are the names of the major enzymes found in each of these locations along the digestive tract? How are the digested macronutrients absorbed into the circulatory system?

Description of Digestion Lipids Proteins Carbohydrates Must first be broken down into smaller units before it can be absorbed by the intestinal wall cell Broken down by enzymes embedded in the cellular membrane of the intestinal wall cell Broken down into smaller molecules by bile salts Volume entering the small intestine: 9600 ml What percentage of the water entering the small intestine is absorbed by the small intestine? Volume entering the large intestine: 600 mL Volume leaving the large intestine:...
Which of the following statements is FALSE regarding the digestive system? O A. In the stomach, the presence of food produces gastrin, which leads to a lowering of pH, which then activates pepsin for digestion of proteins. OB. As food passes through the liver it is mixed with bile which breaks large clusters of fats into smaller droplets. OC. Nutrient absorption takes place primarily in the small intestine. OD. Lipases in the small intestine break lipids into glycerol and free...
