If red blood cells are placed in a solution that is hypotonic the cells will: a. shrink b. swell c. remain the same d. change depends on type of solutes 3. Using the information presented in lecture which of the following is most likely to be the source for the keto acid necessary for the production

Different assumptions which make a custom look to the person consuming sweets is bad‚ one of the most mistake is belief that eating too many sweets causes diabetes‚ but if you are a healthy person‚ your body releases insulin to glucose level what you eat candy. Another of these assumptions is what

D.There is no direct contact between the urinary and reproductive tracts. 1 6. Which substance is found in plasma but NOT in filtrate? A.protein B.urea C.water D.glucose 7.

LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood

process of digestion breaks down carbohydrates into sugar molecules (including glucose) and proteins into amino acids. Right after a meal‚ glucose and amino acids are absorbed directly into the bloodstream‚ and blood glucose levels rise sharply. The rise in the blood glucose levels signals important cells in the pancreas‚ called beta cells‚ to secrete insulin‚ which pours into the bloodstream. Insulin enables glucose and amino acids to enter cells in the body‚ particularly muscle and liver cells

in which IDDM‚ and NIDDM are the major types. Insulin-dependent diabetes mellitus (IDDM‚ type 1) is frequently arisen when the immune system recognizes β-cells of pancreatic islet and destroys them. As a result‚ the body is not able to metabolize glucose properly due to lack of insulin production. It is usually affected young adults who are less than forty years old‚ and characterized by polyuria‚ polydipsia‚ polyphagia‚ weight loss‚ nausea and vomiting. On the other hand‚ non insulin-dependent diabetes

Aldehyde and Ketone 1. ALDEHYDE Definition: An aldehyde is an organic compound containing a formyl group. This functional group‚ with the structure R-CHO‚ consists of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group‚ which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group. Aldehydes differ from ketones in that the carbonyl is placed at the end of a carbon skeleton rather than between two carbon atoms

in his heart struggled to work‚ the blood flow slowed down along with oxygen‚ glucose and ions that were required for the heart to pump‚ the cells received more carbon dioxide causing his pH level to drop. The cells had to work twice as hard and fast‚ using more energy and oxygen than normal‚ eventually beginning to cause the cells to die. Both intracellular organelles have membranes. The lack of ATP affects the plasma membrane and that special calcium ATPases had stopped moving calcium from cytosol

first discovered the concept of homeostasis. But it was Walter Cannon‚ a 20th century American physiologist who devised the word “homeostasis” (Marieb and Hoehn 2007). Temperature‚ pH‚ blood pressure‚ water and electrolyte concentration and blood glucose levels are the most important physiological variables maintained by homeostatic mechanisms (Waugh and Grant 2010).). Homeostasis is regulated by the nervous and endocrine system and there are three mechanisms involved in homeostatic regulation; receptor

carbohydrates which are consumed through starchy foods such as potatoes‚ pasta and chips‚ this is stored in the cells of the liver. Food is converted into glucose within the body; some which are burnt immediately to fulfil the needs of the body there and then‚ others are stored in short term stores and is stored in the form of glycogen. Glucose is the only fuel used by the Central Nerve System. Short term stores feed the brain. Long term reservoirs usually built up of fat cells which have the capability
