he stomach has two types of exocrine cells, chief cell which secrete an inactive form of the protein degesting enzymes pepsinogen, and parietal cells , which secrete hydrochloric acid that activates pepsinogen.Both cell types have an abundance of mitochondria ATP production.The chief cells need energy to synthesise pepsinogen and parietal cells need energy to transport hydrogen ions and chloride ions from the blood into the stomach lumen.Only one of this cell types has an extensive roung endoplasmic and abandant Golgi stacks. Would this be the chief cells or parietal cells?why?

Figure 16.7 Which of the following statements about the digestive system is false? a. Chyme is a mixture of food and digestive juices that is produced in the stomach. b. Food enters the large intestine before the small intestine. c. In the small intestine, chyme mixes with bile, which emulsifies fats. d. The stomach is separated from the small intestine by the pyloric sphincter.
Figure 34.19 Which of the following statements about digestive processes is true? Amylase, maltaseT and lactase in the mouth digest carbohydrates. Trypsin and lipase in the stomach digest protein. Bile emulsifies lipids in the small intestine. No food is absorbed until the small intestine.
The stomach has two types of exocrine secretory cells: chief cells that secrete an inactive form of a protein-digesting enzyme, pepsinogen parietal cells that secrete hydrochloric acid (HCl), which activates pepsinogen Both these cell types have an abundance of mitochondria for ATP production - the chief cells for the energy needed needed to synthesize pepsinogen, the parietal cells for the energy needed to transport H+ and Cl- from the blood into the stomach lumen. But only one of these cell types also has an extensive rough endoplasmic reticulum and abundant Golgi stacks. Explain which cell type would have extensive rough ER and Golgi stacks and why. Also explain which cell type would not have as extensive a rough ER and Golgi stacks and why.
When food is digested, it passes through the alimentary canal, or the gastrointestinal tract, beginning at the mouth and ending at the anus. As it travels it gets broken down into smaller and smaller macromolecules until they are small enough to be absorbed into the lining of the GI tract. What cells would you not expect to find in the lining of the GI tract?
If a mutation in a sodium channel in an Intestinal epithelial cell caused a marked decrease In the concentration gradient of sodium across the plasma membrane, which of the following would you expect to observe? a decrease in Na/K ATPase activity. an increase in the movement of glucose across the basolateral membrane to the extracellular space an increase in sodium/glucose co-transport into the cell across the apical membrane a decrease in cytoplasmic glucose concentration
The cells of the stomach that secrete a protein digesting enzyme are ………………… the parietal cells of the stomach. found in the lumen of the stomach. the enteroendocrine cells of the stomach the chief cells of the stomach.
In order to use lipids to produce ATP the first step is beta oxidation of fatty acids which occurs in the cytoplasm of the cell TRUE or FALSE If glucose stores are getting low, non-carbohydrate molecules such as lipids and proteins will be used to make ATP. This is referred to as glucose sparing TRUE or FALSE Our dietary source of carbohydrates comes predominantly from plants. TRUE or FALSE Essential nutrients can be produced in the liver by the interconversion of different macromolecules in the liver. TRUE or FALSE The major lipid in the american diet is triglycerides. TRUE or FALSE All proteins from animal products are complete proteins. TRUE or FALSE

Digestion is the first stage in the extraction of energy from food, but no useful energy is acquired during this stage. Why is digestion considered a stage in energy extraction?
Which of the following best describe the function of goblet cells in the digestive tract? A. produce mucus that protects parts of the digestive organs from the effects of powerful enzymes needed for food digestion B. secrete buffers in order to keep the pH of the digestive tract close to neutral C. provide protection against invading bacteria and other disease-causing organisms that enter the digestive tract in food D. absorb nutrients from digested food and store them for future use
