BCH 3023 – Fall 2008 Final Exam‚ 12/8/2008 Name: _________________________________ 1. The GTP analog‚ ‚-imidoguanosine 5’-triphosphate (Gpp(NH)p)‚ shown below‚ cannot be hydrolyzed between the and phosphates. Predict the effect of microinjection of Gpp(NH)p of G-protein coupled signaling. O N NH O O H N P OO O P OH OH OH O H N N NH2 - O P O- O H H a. Gpp(NH)p is a substrate for adenylate cyclase and‚ thus‚ will decrease the intracellular concentration of

specific substrate acted on by Aldolase B is fructose-1-phosphate (F1P). This then is converted into DHAP and glyceraldehyde. Once the conversion is finished the product can enter the glycolysis cycle to from ATP or energy used for the body. “In normal cellular conditions‚ the primary enzymatic activity of aldolase B is to cleave fructose diphosphate (FDP).” (Roth‚ 2012) A5. Role of Aldolase B Aldolase B is the substance needed to breakdown fructose. Its specific role is to speed up the

The effect of nutrition on the activity of Artemia franciscana Intro: In most ecosystems‚ the availability of nutrition is the most limiting factor of population growth and activity (Fábregas‚ 1997). If there is a lack of food resources in a community or a lack of certain specific dietary requirements‚ then the physiology of that community and it’s fecundity should be noticeably affected. Nutrients like carbohydrates‚ proteins and fats are carried around the body‚ along with oxygen from the

MDP10508 ENDOCRINE AND NUTRITION BIOCHEMISTRY ASSIGNMENT ANSWER ALL OF THE QUESTIONS BELOW. (70 marks) 1. Comment on the statement below: ‘Glycolysis and Gluconeogenesis are reciprocally regulated’ Reciprocally regulated means when one process takes place in a cell‚ the other process will essentially inactivated. This regulation ensures that either glycolysis or gluconeogenesis predominate as to prevent concurrent activity in two closely parallel pathways‚ where if both Glycolysis and Gluconeogenesis

Enzymology‚ Catalytic Mechanism‚ Carbohydrate Metabolism‚ Adenosine Triphosphate Enzymes are proteins and their function is to act as catalysts to speed up certain chemical reactions in the cell that would be slower without them. This process occurs as steps in a cycle with separate reactions in each step. If there is a missing product the step in the cycle will be incomplete and the normal function of the organism cannot be accomplished causing negative effects on the organism. The biological

semi-permeable and possesses the ability to control the movement of diffusion. Within the centre of a cell‚ the vacuole that is responsible for storage and the maintenance of osmotic balance can be located. In this study‚ we are using beets to study these cellular structures. Beet is a plant whose cells contain a characteristic red pigment‚ called betacyanin. It is located in the vacuole‚ which is surrounded by the tonoplast membrane (Biology 107 Lab Manual 2010-2011). In order for the betacyanin to remain

Human bioenergetics has dependably been an exceptionally intriguing‚ yet complex point. In any case‚ knowing the fundamentals on how our bodies create vitality can be exceptionally valuable when additionally talking about weakness. A basic thought to recollect is that muscle compression is because of a particle called ATP (adenosine triphosphate). ATP must be available for muscles to contract. There are three frameworks of energy that create ATP: Phosphocreatine system‚ the glycolytic system‚ or

Oxygen Requirements of Bacteria BACKGROUND The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms. A candle jar is useful
