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

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, 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?
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.
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
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.
Put the following terms in their correct order from the simplest to the most complex. Skin cell, Integumentary system , Epithelial tissue, Stem cell , Skin, Organism The stomach produces hydrochloric acid which increases the acidity of the stomach to digest the food. However, the small intestine are not damaged by strongly acidic food coming from the stomach. How does our body avoids damaging the small intestine with this strongly acidic food passes out of the stomach?
Which of the following cell types leads to a decrease in pH in the stomach? Schwann cells O Parietal cells Chief cells O Neck cells O Enterokinase cells
Describe how chief cells and parietal cells work together to ensure efficient protein digestion in the stomach.
Food digestion occurs in much the same way in all vertebrates and many invertebrates. Which describes this common process?
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.
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
Experiments have been done on mice where they take away nucleic acids from their diets. Their findings showed that the mice without nucleic acids in their diet grew more slowly and also has shorter villi in their small intestines. Why might it make sense that a mouse with shorter intestinal villi would have slower growth? 1-Shorter villi in the small intestine would mean a reduced ability to absorb food only. 2-Shorter villiv inthe small intestine would mean a reduced aboilty to dihgest food and a reduced ability to absorb food. 3-Shorter villi in the small intestine would mean a reduced ability to digest food only. 4-shorter villi in the small intestine would mean a reduced ability to digest food and an increased ability to absorb food.
