Lactase Buffer solutions 4,7,9 Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently altered themselves. In general, enzymes speed up the rate of reaction by lowering the activation energy required to start reactions. Lactase is an enzyme used by the body to hydrolyze lactose, a disaccharide unique to mammalian milk, into the monosaccharaides, glucose and galactose. Lactose has been shown to aid in the absorption of several minerals, including calcium, magnesium, and zinc. .
Your answer : c. [H+ ] will increase and [HCO3- ] will decrease. Stop & Think Questions: The condition you just simulated is Your answer : a. respiratory acidosis caused by hypoventilation. Correct answer: b. respiratory alkalosis caused by hyperventilation. Can the renal system fully compensate for acidosis or alkalosis? Your answer : c. Yes, both for respiratory alkalosis and respiratory acidosis.
Glucose travels in the plasma or liquid part of your blood but cholesterol (triglycerides) travel bound to protein carriers in the blood. Based on their respective chemical properties, explain the reason for this difference. (2 marks) Cholesterol is an amphipathic molecule, since it has polar and non – polar regions. Even though the cholesterol has polar group (OH) it dissolves fats than in aqueous
Controlled Variables. temperature; pH; sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. The amount of product produced is an indicator of sucrase activity. This is an indicatore because sucrase is an enzyme found in the small intestine that catalyzes the splitting of the disaccharide sucrose into the monosaccharides glucos and fructose.
This amylase converts the remaining starch into maltose. Maltose and lactose are absorbed into the small intestine. Multiple enzymes reside in the microvilli that lines the small intestine: maltase, lactase and sucrose. They’re called brush border enzymes The brush border enzymes convert the disaccharides into monosaccharides: glucose, fructose, and galactose. The monosaccharides are them absorbed into the bloodstream.
Renal Calculi, more commonly known as Kidney Stones, is a common diagnosis pertaining to the urinary system. These stones are formed by small salts and minerals in the urine and are unable to travel to the urethra which can cause extreme discomfort. Some symptoms of kidney stones are frequent urge to urinate, vomiting, blood in the urine, and back/abdomen pain. The kidneys are a major organ in our body that continually filter and balance the fluids, although when minerals and electrolytes in the body become unbalanced a kidney stone will typically occur. Hypernatremia- is a high amount of sodium.
Kidney failure and its scientific solutions Figure 1: ALL ABOUT OUR KIDNEYS, 2015 Kidneys are bean- shaped excretory organs found in the body. There are two of them in the body. They are positioned against the back muscles in the upper abdominal cavity, one on the left and the other on the right. The right kidney is lower than the left one because it needs to accommodate or provide space for the liver. The kidneys remove waste products like excess salts, toxins and urea (a nitrogenous based compound that is produced after deamination) from the blood and they balance water and the body fluids.
Secretes pancreatic juice, insulin, glucagon, duodenum, and somatostatin into the bloodstream. Regulates blood sugar and completes the breakdown of protein, carbohydrates and fats 17. Responsible for the production and maintenance of the protective mucous blanket by synthesizing and secreting glycoproteins known as mucins. 18. Stores and concentrates bile 19.
Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
Even though there is not one test that can diagnosis lupus but with every test that you take will help pin point the severity of the illness. Routine blood test are taken to check you complete blood count levels in lupus the blood tests are low. Urine test are taken because lupus attacks the kidneys. The most common urine tests look for cell casts which is bits of cells that normally would be removed when your blood is filtered through your kidneys, and proteinuria which is a protein being spilled into your body because your kidneys are not filtering the waste properly. Erythrocyte sedimentation rate are taken to determine the rate at which the red blood cells settle to the bottom of a tube in an hour.
