1.) what is the optimal pH for pepsin? where is pepsin found?

Biology

guajiro [1.7K]2 years ago

Answer: 1. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). 1.0–2.0

The optimum pH for pepsin activity of 1.0–2.0 is maintained in the stomach by HCl. When the pH of the medium increases to values greater than 3.0, pepsin is almost completely inactivated. 2.  The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denatured. The enzyme salivary amylase is most active at pH 6.8.  around 7

Salivary α‐amylase has a short‐lived action. In fact, it is swallowed with chewed food and subsequently inactivated by extremely low gastric pH; amylase in fact has an optimal pH around 7, and the pH of saliva is generally between 6.4 and 7.0.

Answer:

What Keene High school students are you reading about? And what scientist are you talking about? If you had given more information I would have helped. Anyways, just look at what it says in the book that the scientist did, and what the Keene high school students did. And see what they both have in common.

What are frankenfoods? Are Genetically Modefied foods safe?
barxatty [35]

Opponents of GMOs have been unceasing in their campaign to vilify genetically modified foods by describing them as “Frankenfoods,” thus implying they are not natural and are potentially harmful.

“The practice of introducing new DNA and chemicals to seeds or animals (Aqua Advantage has developed a GMO fish) is similar to how Mary Shelly’s Frankenstein created his monster–—through piecing together lots of different organisms,” wrote the Organic Authority on its website—a common allusion in the anti-GMO world. “We all know what happened when the monster turned on Frankenstein, and many critics of genetic engineering have likened the inevitable backlash of GMO technology to the destruction and murderous rampage of Frankenstein’s monster.”

Many anti-GMO articles that warn of the dangers GM crops are often accompanied by an image of a tomato fruit or vegetable with syringes sticking out of them. Very often it is a fruit or vegetable for which there is no current GM equivalent such as a tomato. This depiction is used to reinforce the notion that GM foods are created in laboratories and not by nature and therefore are dangerous to consume.

With the constant barrage of scare-based imagery, it is not surprising that there is widespread public suspicion that GMOs are dangerous to human health. But there is little controversy surrounding GMOs within the scientific community with 88 percent of the members of the American Association for the Advancement of Science believing GMOs are “generally safe.” The safety of GMOs were once again reinforced by the May 2016 report by the U.S. National Academy of Sciences, Engineering and Medicine, which concluded, there was “reasonable evidence that animals were not harmed by eating food derived from genetically engineered crops”, and epidemiological data indicated there was no increase in cancer or other health related problems associated with these crops entering our food supply.

David Zilberman, a professor of agriculture and resource economics at the University of California, Berkley, has noted that Frankenfood was “a terrible word, a stigmatization word, one that’s used to scare people… People are afraid of GMOs for little or no reason. GM is simply a tool. Because it allows us to modify plants with far greater precision and control then before, it will be very valuable.”

The reality is that the vast bulk of the foods we consume whether organic or conventionally grown have had their genetics altered in the field or in a laboratory via a process of selective breeding or advanced biotechnology techniques, and all such foods are safe to eat. The altering of genes in plants is even known to occur naturally as highlighted by the sweet potato.

densk [106]

The anterior rami of the brachial plexus are the continuations of the anterior rami of spinal nerves  C5-T1 . These rami emerge from the intervertebral foramina and travel through the neck. The five rami unite to form the superior, middle, and inferior trunks  in the posterior triangle of the neck. Nerves C5, C6 unite to form the superior trunk; nerve C7 remains as the middle trunk; and nerves C8,T1 unite to form the inferior trunk. Portions of each trunk divide deep to the clavicle into an anterior and a posterior division. These primarily contain axons that innervate the anterior and posterior parts of the upper limb. Upon reaching the axilla, they converge to form three cords.
