Biology: A Case Study Of Diabetes

For instance, after ingestion of a meal, the blood glucose level rises, which causes the beta cells of pancreas to secrete insulin. There are many effects of insulin such as increases the cellular rate of glucose utilization as an energy source, it stimulates most body cells to increase their rate of glucose uptake (transport) from the blood, it stimulates fat synthesis (from glucose) in liver cells and adipose (fat) tissue and accelerates the formation of glycogen from glucose in liver and skeletal muscle cells. This affects will later then decrease the blood glucose level to normal

Independent Variable amount of substrate (sucrose) present 3. 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. I believe glucose and fructose was used as an indicator because they are what produces sucrose and sucrose creates more sucrase activity.

Similarly, as blood glucose falls, the amount of insulin secreted by the pancreatic islets goes down. Insulin has an effect on a number of cells, including muscle, red blood cells, and fat cells. In response to insulin, these cells absorb glucose out of the blood, having the net effect of lowering the high blood glucose levels into the normal range.

Insulin is a hormone produced by the pancreas. Insulin works in the body by acting as a key to bring glucose levels to normal. So when the stomach breaks down food, some of it is broken down to sugars called

INTRODUCTION Metabolic syndrome (syndrome X, insulin resistance syndrome) consists of constellation of metabolic abnormalities which include central obesity, hyperglycemia plus insulin resistance, high triglycerides plus low HDL cholesterol, and hypertension.1 NCEP:ATP III 2001 Criteria for the Metabolic Syndrome2 :- Three or more of the following: . Central obesity: Waist circumference ≥102 cm in males or ≥ 88 cm in females .Hypertriglyceridemia: triglycerides ≥ 150mg/dl .Low HDL cholesterol < 40 mg/dL (males) or < 50 mg/dL (females) .Hypertension : blood pressure ≥ 130mm systolic or ≥85mm diastolic .Fasting

Hormones are chemicals emitted by organs. Hormones are chemicals emitted by organs. They go through the circulatory system and influence target organs. Sexual advancement, the menstrual cycle and ripeness in women, and glucose levels, are altogether controlled by hormones. Homeostasis it is critical that the body 's inner surroundings are controlled.

• Question 27 1 out of 2 points Which of the following is true of insulin? Select all that apply. Selected Answers: A. it is secreted when serum glucose levels are elevated B. it acts as the primary catabolic hormone C. it stimulates gluconeogenesis D. it binds to GLUT 4 receptors on the cell membrane Answers: A. it is secreted when serum glucose levels are elevated B. it acts as the primary catabolic hormone C. it stimulates gluconeogenesis D. it binds to GLUT 4 receptors on the cell membrane Response Feedback: CHO PPT Part 1 Slides 34-7 • Question 28 1 out of 1 points Gluconeogenesis is sometimes referred to as the reverse of which pathway?

The pyruvate molecules that were created in glycolysis are then sometimes fermented into lactic acid. Lactic acid can be used to transform lactose into lactic acid, for example in the making of yoghurt. This process is also used in animal muscles when they require extra energy in their tissue in order to run faster than oxygen can be given. C6H12O6 (glucose) > 2CH3CHOHCOOHc*lactic acid) is the net equation for glucose to lactic acid.

The adrenals are known for making the hormone adrenaline but also, they make the corticosteroids which affect your metabolism and sexual function. The pancreas is part of the the digestive system and the endocrine system. It makes the hormones insulin and glucagon. These help ensure you have the right amount of sugar in your bloodstream and your cells. If you don 't make any insulin, which is the case for people with type one diabetes, your blood sugar levels can get dangerously high and if the body makes some insulin but not enough, that is type two diabetes.

An investigation of the relationship between different concentrations of Sodium Chloride and the rate of reaction of Amylase Marjolijn Hoogevoorst Yeshvanth Prabakar IS12 Word count: 2222 words Introduction: Enzymes are biological catalysts that speed up reactions by lowering the activation energy. Amylase is a type of digestive enzyme found in the pancreases and saliva of humans. Amylase breaks down starch into sugar, allowing large molecules to be digested easily.

By blocking alpha receptors, this adds to the blood vessel dilating effects. Some of the beta blockers have intrinsic sympathomimetic activity (ISA), which means they mimic the effects of norepinephrine and epinephrine and cause an increase in blood pressure and heart rate. (Ogbru & Marks,
