Chemical Reactions And Gas Laws

Beano’s chemistry, enzymes, and flatulence. During the project it stated that enzymes act like a key and lock mechanism. Enzymes can target specific molecules and only allow certain reactions to take place. There are also rate-determining factors that determine the speed of the enzyme reactions. Since enzymes are catalysts, they are not used up in a reaction; this means that other factors determine the rate of catalytic reactions. Rate of diffusion is a factor that can govern the rate of enzyme activity. Another factor that determines the rate of these reactions is the concentration of the substrate. The principle behind this is that more substrate molecules will increase the frequency of enzyme-substrate interactions. This will eventually

There are many types of enzymes and each has a specific job. Enzymes are particular types of proteins that help to speed up some reactions, such as reactants going to products. One of them is the amylase enzyme. Amylases are found in saliva, and pancreatic secretions of the small intestine. The function of amylase is to break down big molecules of starch into small molecules like glucose; this process is called hydrolysis. Enzymes are very specific; for example, amylase is the only enzyme that will break down starch. It is similar to the theory of the lock

Healthy digestive system is needed to have a proper elimination. This family suffered from chronic constipation, irregular bowl patterns, gas and heart burns. High stress and taking multiple over the counter medications contributed to this families altered elimination patterns. Their diet consists of foods that have low fiber, high starch and high fat, resulting in the constipation. Father suffered from prostate problems, which made him wake up multiple times middle of the night to urinate.

Most organisms rely on enzymes to digest their food. In all reactions, there is an activation energy barrier. During digestion, foods must be broken down quickly so that the organism can get the nutrients it needs. In order for the food to be broken down, the activation barrier must be lowered. Without enzymes, many organisms would no longer be able to obtain the nutrients and energy they need to live. In this experiment, the goal was to understand how and why enzymes work in such specific ways, and to discover how enzymes function under different conditions.

Enzymes are catalysts that help promote chemical reactions by integrating or breaking apart biological molecules. Most metabolic processes in the cell need enzymes to occur at rates quick enough to sustain life. Because enzymes are particular with what substances they choose to speed up, they only affect a tiny percentage of all the possible reactions. The group of enzymes made in a cell determine which metabolic pathway is selected. Enzymes are critical to the human body, specifically the body’s metabolism system. The metabolic system is a long series of continuous chemical reactions, and these catalysts boost efficiency and effect (Audesirk, Byers 99-102). Every enzyme affects a particular and specific part of the system, and

Chemical reactions are important.Without a freezer coud ylou have nice cold ice cream and without an oven could you have roast chicken or oven fries and the answer is no. Ovens and freezers are very similar as inside heaps of chemicals are reacting to the food so it is either hot or cold.

Enzymes are important in digestion. Enzymes are important molecules; which are particularly important to digestion since they help break down large, insoluble food molecules into the opposite; to small, soluble molecules which can be easily absorbed. Enzymes work best at their ideal pH. For example, if the stomach was to not to produce enough HCL (hydrochloric acid), the enzyme pepsin would not work properly, since the ideal pH for pepsin is 2. The three main enzymes of our gut are; protease, carbohydrase and lipase.

Peristalsis is one the most significant mechanical motions of the gastro-intestinal tract. The longitudinal and circular muscle fibres that form part of the oesophagus, stomach, intestines and colon trigger involuntary contractions that are strong enough to propel food matter through their tract. Once the bolus enters the oesophagus peristalsis is the predominant means of mechanically transporting food throughout the remainder of the digestive tract. Peristaltic waves move the bolus through the oesophagus to the stomach, any remaining food in the oesphagus is then propelled by secondary peristaltic waves. ‘One wave travels the full length of the tube in about 9 seconds’ (Britannia.com,2015).

Gastro-esophageal reflux disease (GERD) is a medical condition where abnormal distal esophageal acid exposure caused by reflux of acid contents results in troublesome symptoms1, 2. It is caused by the failure of endogenous anti-reflux barriers such as the lower esophageal sphincter1. Small amounts of reflux occur naturally throughout the day in everyone but normal anatomy and physiology of the esophagus, lower esophageal sphincter, diaphragm muscles at the hiatus and stomach prevent pathological GERD3. The worldwide prevalence of GERD is estimated to be 13-19%, with 35% suffering symptoms at least monthly, 12% at least weekly and 5% daily4 though different sources have

During lunch, I felt a burp coming on. I let loose with it and took my hands and pushed on my stomach as the burp happened. The issue with this is that the burp kept coming and the volume seemed to increase exponentially with the length of the burp. All I can remember is that the burp was almost inhuman and at the time, the crew was in the back of the restaruant in the kitchen. If you’re ever seen the movie Revenge of the Nerds II, think of the scene where Booger meets Snotty and Snotty burps and shatters the mirror in his room. This was one of those

Gastroesophageal Reflux Disease, or GERD, occurs when there is a backflow of stomach contents, also known as chyme, from the stomach to the esophagus causing irritation and damage to the esophageal lining. When things are consumed by mouth, contractile motions in the esophagus move substances down the esophageal tract and into the stomach.  The lower esophageal sphincter is an area of smooth muscle at the end of the esophagus that works with the diaphragm to let the food, liquid or medication into the stomach. The stomach produces acid and is constructed to withstand this acid, but the esophagus is not.  Normally,  the lower esophageal sphincter keeps stomach contents, including food,

This year in Science I have grown in a variety of topics. In Science we do many labs and other activities that help me understand the content. The thing I have grown the most in, however, is understanding what happens to atoms and molecules during a chemical reaction. After learning, expanding upon, and deepening my understanding of what happens to atoms and molecules during a chemical reaction, I was able to show my knowledge and skills during tests and quizzes. In this reflection I will be sharing artifacts that display my moments of growth including accomplishments and obstacles.

Those results may have stemmed from the widespread belief that the bowels should be open daily and that failure to do so will cause any umber of complaints ranging from headaches to depression. In fact, one medical study has shown that the average person may pass faeces as little as twice a week or as often as three times every day.

“Aspiration is defined as the inhalation of either oropharyngeal or gastric contents into the lower airways, that is, the act of taking foreign material into the lungs” (Stearns, Swaminathan, Varkey, Varkey, 2015). Ordinarily the body has structures and defenses to prevent aspiration of foreign matter into the lungs. The epiglottis is a leaf like structure that closes off the glottis to divert food, particles, and liquids to the stomach and prevents entry into the lungs. In cases that the epiglottis fails to function properly, entry of the particles enters, or is aspirated, into the upper airways and lung tissues. Gastric fluid entering the lung tissues can cause damage to the alveoli in the lungs by washing out the surfactant and causing the

Gas go into the body through the pair opening in the body called spiracles. Filtering devices prevent small particles from dogging the system and valves control the degree to which
