After doing a body check-up, Sam found out he had an extremely low level of trypsinogen. Discuss what will happen after Sam eat a meal high in protein and fat.
(Your answer should mention location of secretion, location of activation, negative consequence if the enzyme does not function properly.)
If Sam had an extremely low level of trypsinogen, then he couldn't break down proteins from foods into their basic subunits, while fats were normally metabolized.
What is trypsinogen?Trypsinogen is a precursor of the trypsin enzyme which is used by the body to degrade proteins into their amino acids. All proteins are composed of amino acids, which represent the building blocks of these biomolecules.
Therefore, with this data, we can see that trypsinogen is fundamental to degrading proteins onto their subunits (i.e., their amino acids), thereby the absence of normal levels of this precursor enzyme would be dangerous for the health of the organism.

What happens during radioactive decay?
answer: Parent isotopes turn into daughter isotopes
Answer: I hope this helps. Let know if this right or wrong. Have a good day
Explanation:
When radioactive atoms decay, they release energy in the form of ionizing radiation (alpha particles, beta particles and/or gamma rays). The energy is called ionizing radiation because it has enough energy to knock tightly bound electrons from an atom's orbit. This causes the atom to become a charged ion.During radioactive decay, an unstable nucleus emits subatomic particles to attain stability. It may undergo transmutation to change to some other nucleus or may achieve a stable state by giving off energy in the form of photons. Radioactive decaya radioactive process in which a nucleus undergoes spontaneous transformation into one or more different nuclei and simultaneously emits radiation, loses electrons, or undergoes fission.
which organisms do not use nadh to feed electrons into mitochondrial electron transport chains? group of answer choices animals that do not maintain a constant body temperature plants animals that maintain a constant body temperature eukaryotic algae bacteria and archaea
The statement "animals that do not maintain a constant body temperature" is correct, they are the organisms that do not use NADH to feed electrons into mitochondrial electron transport chains.
Animals that do not keep a constant body temperature do not need NADH and do not consume NADH during respiration, as NADH is needed for maintaining a constant body temperature and is thus required by the organism.
The second method uses the respiration process used by bacteria and archaea, which uses NADH. The eukaryotic algae in the third option employ NADH in respiration since eukaryotes often do so. In the fourth option, animals must use NADH for respiration in order to keep their body temperatures constant.
If NADH is not available, oxidative phosphorylation reactions uncouple, which maintains the body temperature. This type of reaction is seen in animals that are hibernating as well as in newborn animals and people.

Esters of glycerol, fatty acids, phosphoric acid, and other alcohols make up phospholipids.Phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylserine are the four most prevalent phospholipids.
Where are phospholipids found in food?
The plasma membrane, the top layer of animal cells, is largely made up of phospholipids.They are made up of fatty acid chains joined to a glycerol backbone, just like fats.Phospholipids have two fatty acids that contribute to the formation of a diacylglycerol, as opposed to triglycerides, which have three fatty acidsPhospholipids are amphiphilic lipids consisting of a glycerol backbone or an amino-alcohol sphingosine backbone, which is esterified to one or two fatty acids, a phosphate group and a hydrophilic residue.Good sources of phospholipids include eggs, organ meats, lean meats, fish, shellfish, cereal grains, and oilseeds, particularly the choline phosphatides phosphatidylcholine, sphingomyelin, and lysophosphatidylcholine. Glycerophospholipids and sphingolipids are two kinds of lipids that make up the significant class of membrane lipids known as phospholipids. The cell membrane is composed of phospholipids, which are created when glycerol interacts with two fatty acids and a phosphate group.One phosphorus atom and four oxygen atoms combine to generate the complex ions known as phosphotes.Another form of lipid that does not contain glycerol is steroids. A phospholipid is a molecule made composed of a glycerol backbone, two fatty acids, and a modified phosphate group.The phosphate can change by having polar or charged chemical groups added to it. These hydrophilic and hydrophobic characteristics of phospholipids lead them to group into two layers when cellular membranes are formed.Because they are hydrophobic, the phosphate tails in between the layers of heads avoid contact with the water while the heads in each layer face the aqueous or watery environment on either side.

If you pinch your nose while you are putting a piece of food into your mouth, what are you going to experience?.
If you pinch your nose while putting food in your mouth, you may experience lack of taste in the food.
It did appear that smell had an impact. However, the ability to taste was not completely impaired by nose plugs. Chewing certain foods allows aromas to reach the nose through the back of the mouth even when the nostrils are closed because the nose and throat share essentially the same airway.
Molecules from your food travel up your throat to the olfactory epithelium, where they activate odor receptors, when you eat.
Retronasal olfaction, as opposed to orthonasal olfaction, which occurs when you sniff through your nose, is prevented by pinching your nose. Retronasal olfaction is very important to your sense of flavor, which many other people mistake for "taste.", we can demonstrate this with jelly beans: you can still taste the sweetness of the jelly bean by pinching your nose, but you can't tell the difference between a strawberry and a grape.
