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.

Polyethylene glycol (PEG) is a solute that is consumed in order to "clean out" the digestive tract in preparation for a colonoscopy. PEG cannot enter intestinal cells as there is no transport mechanism for it. How would this affect the absorption of water into the small intestine? (assume that it is taken at the correct dose and you are not actually reversing the concentration gradient across the intestinal cells.) Explain your answer in terms of concentration gradients.
When LDL (low density lipoprotein) is taken up by cells during pinocytosis, all of the following steps in the processing of LDL and its receptor protein occur, with the exception of: LDL is digested in lysosomes, releasing cholesterol to the cytoplasm LDL receptors are digested in the lysosomes along with the LDL LDL attaches to LDL receptors, which form clathrin-coated vesicles the endosomes fuse with lysosomes for digestion of the LDL the vesicles fuse with endosomes, and LDL receptors are recycled
Movement of glucose from one side to the other side of the intestinal epithelium is a major example of transcellular transport. How does the Na+/K+ ATPase power the process? Why are tight junctions essential for the process? Why is localization of the transporters specifically in the apicalor basolateral membrane crucial for transcellular transport? Rehydration supplements such as sport drinks include a sugar and a salt. Why are both important to rehydration?
Which of the following contain a correct first statement and an incorrect second statement? Beta- and gamma-subunits of the G-proteins activates adenylyl cyclase. Phospholipase C is a membrane-bound enzyme that cleaves phospholipids bound to the membrane. Polyols are highly oxidized molecules which makes them impermeable to the intestinal lining. Increasing heat of saccharin solution renders it to degradation. Intestinal microbiota utilizes reduced carbohydrate sweeteners resulting to energy production. Dextrose is a sugar that rotates the plane of polarized light in a counterclockwise manner. All natural sweeteners are nutritive. Theory of sweetness provides information on the interaction of the "sweet molecule" and its corresponding receptor.
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
Cotransport systems of the internal epithelial cells include the _____ in the intestine facing membrane, the energy requiring _____ facing the blood, and the ________ allowing facilitated diffusuon of glucose out of the cell.
Glucose diffuses slowly through artificial phospholipid bilayers. The cells lining the small intestine, however, rapidly move large quantities of glucose from the glucose-rich food into their glucose-poor cytoplasm. Using this information, which transport mechanism is most probably functioning in the intestinal cells? exоcytosis simple diffusion O phagocytosis facilitated diffusion active transport pumps
A normal LDL (low-density lipoprotein) signaling pathway is shown in the image. Familial hypercholesterolemia is a disorder caused by a defect in the LDL receptors on the plasma membrane. What would be the consequence of this defect on the cell? The cell would increase production and exportation of HDL to remove LDL from the bloodstream. Additional LDL receptors without the defect would be formed and added to the plasma membrane. Increased fluidity of the plasma membrane would allow more water-soluble molecules to pass into the cell. The cell would produce greater amounts of ATP so that LDL could enter the cell through active transport instead of receptor-mediated endocytosis.
Acetylcholine is a neurotransmitter that, when bound to its receptor, causes the receptor to open a channel that allows the flow of Na+ ions into neurons. When the Na+ ions begin to flow into the neuron, this change in the net charge across the neuronal cell membrane often triggers Ca2+ ion channels to open. In this scenario, the acetylcholine receptor would be acting as a channel, and the Ca2+ channels would be classified as voltage-gated; leaky ligand gated; voltage-gated symporter; antiporter None of the above. ion
The liver is known for its ability to remove certain toxins from the blood. It can it is made up of hepatocytes that contain large quantities of lysosomes and peroxisomes, as well as having an extensive smooth endoplasmic reticulum. Describe how these three organelles contribute to this major function of the liver (briefly).
is/are functions of the peroxisome. Choose all that apply. There are 3 correct answers. You will LOSE points (from the total correct) for incorrect answers. This is to discourage guessing. oxidation of fatty acids recycling of cellular components autophagy detoxification of harmful compounds hydrogen peroxide metabolism extracellular digestion
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?
