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 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.
The stomach has two types of exocrine cells: the chief cells, which secrete an inactive form of the protein-digesting enzyme pepsinogen, and the parietal cells, which secrete hydrochloric acid (HCl) that activates pepsinogen. Both cell types have an abundance of mitochondria for ATP production- the chief cells need energy to synthesize pepsinogen, and the parietal cells need energy to transport hydrogen ions. (H+) and chloride ions (Cl-) from the blood into the stomach lumen. Only one of these cell types has an extensive rough endoplasmic reticulum and abundant Golgi stacks. Would this be the chief cells or the parietal cell? parietal cells.
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.
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
Carnitine shuttle is used to Transport FA chains from the adipose tissue to the liver. Transport FA chains from the blood-stream to the cytosol. Transport FA chains from the cytosol to the mitochondrial matrix. Transport FA chains from the mitochondrial matrix to the cytosol.
Enzymes that digest dietary proteins in the stomach and intestine are synthesized as proenzymes or zymogens. Which of the following is the proenzyme form of a proteolytic enzyme of the digestive tract? elastase O carboxypeptidase chymotrypsin
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?
Which is a correct statement about the Na+/K+ transporter (pump), and its cytology and cellular role? It is found the basal side of intestinal epithelial cells, pumping Na+ out of the cell into the blood. It is found on the plasma membrane of neurons, pumping Na+ into axons from the blood. It is found on the membrane of the lysosome, pumping K+ into the lumen of the lysosome. It is found on the apical side of intestinal epithelia, pumping K+ into the lumen of the intestine.
Drag and drop each event of nutrient use and storage to the correct state of digestion in which the event occurs. Triglycerides are broken down to fatty acids and glycerol and then converted to glucose Nutrients are taken up from the intestinal lumen Amino acids are Glycogen is broken down to glucose Gluconeogenesis transported into muscle and used to form protein and enter the blood Excess glucose is stored as glycogen Glucose or fatty acids are used for cellular ATP production to meet energy needs Triglycerides are stored in fat cells Glycogenolysis Absorptive and postabsorptive Absorptive Postabsorptive Reset
Actions of Digestive Secretions The breakdown of food into nutrients requires secretions from different organs or glands. Many of these secretions contain enzymes or other compounds that break down one or more of the macronutrients. Five secretions involved in the digestive process are listed below. Choose the macronutrient(s) that each secretion either breaks down or facilitates the breakdown of. Note that some secretions may support the breakdown of more than one macronutrient. Secretion Intestinal juice Gastric juice Pancreatic juice Saliva Bile Proteins Carbohydrates Lipids □
Describe the two fates of glycerol after it has been converted to an intermediate of glycolysis. Describe what happens to the level of blood lipids after a meal rich in fat. What happens to the products of triglyceride digestion as they pass into the cells of the intestinal mucosa?
It's halloween and you just ate 27 Reese's peanut butter cups. Describe the ENTIRE process of both chemical AND mechanical digestion from mouth to anus of all of the nutrients in this candy (hint: there are carbs/fats/and proteins present). Your response must include the passing of the candy through all major organs and the role of accessory organs. You must also include key enzymes involved in breaking down each nutrient type AND include key words like bile, chyme, bolus, etc.
