Why did scientists originally hypothesize that proteolytic enzymes such as pepsin and trypsin are secreted in inactive form?.
Scientists originally hypothesize that proteolytic enzymes such as pepsin and trypsin are secreted in an inactive form because these proteolytic enzymes, in active form, would digest the very tissues that synthesize them.
Both pepsin and trypsin are proteolytic enzymes, which means that they are involved in the breakdown of proteins.
Pepsinogen is the inactive form of pepsin. The chief cells of the stomach originally secrete pepsinogen which is then converted into pepsin only when the food arrives in the stomach. Trypsinogen is the inactive form of trypsin, that is secreted by the pancreas. The trypsinogen is converted into trypsin only when it has been transported to the small intestine and when the process of digestion is occurring.
Both these enzymes are secreted in inactive forms because if secreted in their active forms they would digest all the other important proteins of the very cells that are making them. Hence, scientists originally hypothesized that proteolytic enzymes such as pepsin and trypsin are secreted in an inactive form.

What path does a protein in the secretory pathway take, starting from its site of synthesis?.
Every protein starts its production in the cytoplasm. However, some are moved to other cellular locations while the majority remain there permanently. Post-translational transport may be used to import them into the mitochondrion, peroxisome, chloroplast, and nucleus.
Beginning with the intake of amino acids, which are utilized by the rough endoplasmic reticulum to create freshly produced proteins, the secretory route proceeds in a vectorial fashion. The Golgi complex receives these new proteins and processes and sorts them there. Protein cargo is transported from the ER to the Golgi, where it is altered before being transferred to various locations inside the cell, such as the lysosomes and the cell surface. Proteins produced by the endoplasmic reticulum (ER) are processed in the Golgi before being sent to the cell.learn more about protein here: https://brainly.com/question/10058019

Imagine you are the uta for the freshman biology course. how would you explain to miguel's roommate what hyperthermia is and how dnp use causes hyperthermia?
I would make an effort to explain to my roommate, Miguel that ingesting DNP results in the release of calcium reserves from mitochondria and hinders re-uptake, which in turn leads to unopposed muscular contraction and hyperthermia in muscle cells that have free intracellular calcium.
2,4-Dinitrophenol (DNP) C₆H₄N₂O₅ is a weight loss supplement. However, because of its lethal side effects, it was considered to be unsafe for human consumption and was banned by the FDA in 1938.
DNP causes a rise in metabolic rate and heat by decoupling oxidative phosphorylation and limiting ATP synthesis. DNP inhibits the uptake of phosphorus into the mitochondria. Additionally, DNP makes it possible for hydrogen ions to sneak past the mitochondrial membrane and avoid ATP synthase. As cells try to produce more ATP, the potential energy that is typically retained during ATP creation is released as heat, leading to hyperthermia and increased calorie consumption through more carbohydrate and fat breakdown. It was because of this quality that it gained popularity as a weight-loss medicine in the 1930s and remains so today.

To isolate the the serum, and not the plasma, from the blood if you just withdrew a fresh vial of blood from the sheep without adding any anticoagulant, you should let the blood sit for 10 minutes, then withdraw the top layer (serum). Hence, option b is correct.
Without using a centrifuge, whole blood can be separated from plasma or serum by simply letting it stand or just sit for about 10 minutes . All of the cells will eventually settle down due to gravity (if time is not the question). The supernatant is the plasma if citrated blood is allowed to stand in a tube.
The serum will eventually separate, though, if you leave the undiluted whole blood to stand. This might not be as useful if you are working with small amounts of blood, but you could still try it.

Richard feels that the increasing use of fuels such a coal or diesel to generate electricity are leading to pollution in his neighborhood. He therefore decides to use solar energy as a source for generating electricity. Which device should Richard use?
The potential for solar energy is the highest of all the available renewable energy sources. The two main solar energy technologies are concentrated solar-thermal power (CSP) and photovoltaics (PV) (CSP).
Unlike fossil fuels, which will eventually run out, the sun has more than enough energy to supply the demands of the entire planet. The sole constraint on solar energy as a renewable resource is our capacity to efficiently and economically convert it to electricity. Some energy sources, as opposed to fossil fuels, are entirely renewable and don't release greenhouse gases. Solar energy, hydropower, wind, geothermal, and biomass energy are some of these green and sustainable alternative energy sources. The energy sources that are now available are quickly running out due to the rising demand for energy. Large-scale fuel use results in the release of many gases and undesirable airborne particulates.
