Lactase

Although it varies from country to country, "Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy. ("Lactose Intolerance ")" Lactose intolerance is caused from an inability to properly digest lactose. Lactase is the enzyme that breaks down lactose and those who do not produce enouh of it are lactose intolerant. The symptoms of lactose intolerance are "abdominal pain, bloating, flatulence, nausea, and diarrhea beginning 30 minutes to 2 hours…

community, the reason for avoiding milk is quite different, but is closely related the belief in India. The context under discussion here is not from a religious perspective, but rather is from a biological perspective. This community is deficient of lactase, responsible for digestion of milk. It is a genetic aspect associated with early nomads and this speaks of the Pima Indian community being originally nomads. It is important to understand the digestive malfunctioning of different people…

A chemical reaction is the change of a molecule from one arrangement to another. Our whole bodies are made up of cells, which are chemical systems. To sustain life there must be chemical reactions all throughout the body (Barnhart and Hopper 2011). At what rate the reaction can occur is dependent on the activation energy. Activation energy is the amount of energy the reactant molecules must surpass for the reaction to occur (Mathew Bui et al. 2006). Temperature and catalysts are the most basic…

Summary: Barry James, a 67-year-old man presents to the hospital with a recent onset of diarrhea and weight loss; patient has a history of lactose intolerance, vitamin B12 deficiency and intermittent diarrheal episodes that last 1-2 days. Peripheral edema was noted on the physical examination, and the abdominal examination was negative for distention and organomegaly. Question: Describe the pathophysiology and clinical presentations associated with small intestine malabsorption. Generate:…

Cultural Anthropology involves a number of different issues that play a role in our daily ways of life. These include power, subsistence, relationships, and globalization. As we’ve already learned, location plays a huge role in how culture helps shape our lives. Power generally means the same thing around the world; it is the ability to influence someone’e decision and have direction over them. However, the amount of power that individuals hold can vary depending on their rank in their society…

The Electron Transport Chain (ETC) and Oxidative phosphorylation [VII] These processes are the last stages of cellular respiration. NADH and FADH will be transferred into the mitochondria. Oxidation takes place here. The electrons are freed. The electrons will travel through a system of four protein complex structures, known as the Electron Transport Chain. ATP are produced as a result of this transport chain as the electrons are the fuel that drive the oxidative phosphorylation. The presence…

While a genetic link to osteoporosis has been discovered, the gene itself has not yet been isolated. Despite this genetic link, scientists have discovered that osteoporosis has a nutritional component. Calcium deficiencies and hormonal deficiencies have also been linked to osteoporosis. Some people who have no genetic link to osteoporosis find themselves dealing with this condition due to other factors. For example, osteoporosis can be caused by extended treatment with steroids, kidney…

reacting with water. Dehydration synthesis only takes place inside cells. Carbohydrates, it occurs mostly in liver and muscle cells, to make glycogen from glucose molecules. Hydrolysis of carbohydrates occurs in the mouth and small intestine. Sucrase, lactase, and maltase catalyze the hydrolysis of disaccharides…

was my favorite part. I will express what I like and disliked in this paper, give a small summary or the article, and see how Bogin could have expanded on his article in the paper. The first example he explains is the difference of the lactase enzyme, the enzyme which helps break down sugar lactose, in different cultures. Native Americans, Asians, Mediterranean…

Lactase deficiency, or lactose intolerance, birth defects, diseases of the gallbladder, liver, or pancreas, Furthermore, damage to the intestine from either trauma, surgery, infection, or inflammation, and parasitic diseases (Cafasso & Kerr, 2015). The specific…
