Sir Safar Lecture 2 Finals Pentose Phosphate Pathway (S. 70) Alternative pathway for glucose oxidation. Similar to glycolysis‚ but instead of having pyruvate as the end product it is diverted to other pathways. Supplier of energy to the cell in the form of NADPH (a reducing power for biosynthesis). It is also referred to as hexose monophosphate shunt. *Fate of glucose 6-phosphate (G 6-P) IN THE PPP (S. 71) Taken out from glycolysis and converted into Ribulose 5-phosphate. With the conversion

with varying enhancers added to the luminol. The substances to be compared in this study are as follows: cysteine‚ Cu (II)‚ silver nanoparticles (AgNPs)‚ and zinc sulfide nanoparticles (ZnS-NPs). The first experiment focused on the reaction between alkaline luminol H2O2‚ the most common luminol solution‚ and cysteine‚ one of the twenty essential amino acids. In this experiment‚ 105 g=mL cysteine solution‚ 2.0 105 mol=L Cu(II) solution‚ and the mixture of 1.0 105 g=mL cysteine with 2.0 105 mol=L

value from 0 to 14.Pure water at room temperature (77 Fahrenheit)‚ for example has a pH of 7.0 and is considered as a neutral. Water with a pH below 7 is defined as an acid and above 7 is an alkaline. So a pH measurement of 0 represents the strongest acid‚ and a pH value of 14 represents the strongest alkaline. pH levels is very important in food industry as some of the microorganisms can live within a certain range of pH. Objectives : * To recognize the pH value of most of the household products

(ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest ionization enthalpy in their

Chemistry Midterm Essay Describe a major contribution to science made by each of the following scientists: John Dalton‚ (b) J. J. Thomson‚ (c) Robert Millikan‚ (d) Ernest Rutherford. John Dalton was a chemist and a meteorologist‚ with his notable achievements being leading the study on color blindness and modern atomic theory. Born in 1766‚ his later research on color blindness stemmed from his experience with the condition along with his brother. Along with this‚ what is now known as Dalton’s Law

The Effect of Soil pH on the Living Conditions In Lumbricus terrestris Abstract The difference in soil pH weighs a heavy measure on the appearance of the earthworm Lumbricus terrestris in different areas of soil. A highly acidic or highly alkaline soil may be the underlying reason for the absence of this earthworm in certain areas where pH plays a large role. In this experiment‚ soil pH was altered with Miracida soil acidifier and Agricultural Limestonea soil correctional for acidic soil

Lithium Sodium Potassium Rubidium Cesium Francium Elements classified as Alkaline Earth Metals The 6 elements classified as "Alkaline Earth Metals" are located in Group 2 elements of the Periodic Table. Elements classified as Alkaline Earth Metals are all found in the Earth’s crust‚ but not in the elemental form as they are so reactive. Instead‚ they are widely distributed in rock structures. The Alkaline Earth Metals are: Beryllium Magnesium Calcium Strontium Barium Radium

1. Colour Fastness to Light This method is intended for accessing the resistance of the colour of textiles to the action of daylight. Principle: A specimen of the textile is exposed to the light from a Xenon arc lamp under prescribed conditions‚ along with eight dyed wool standards. The fastness is assessed by compared the fading of the textile with that of the standards. Apparatus and Materials: - Blue standards - Humidity Test Control Fabric - Light fastness test apparatus containing

1.3 C. elegans sensory system C. elegans is a simple multicellular organism‚ and‚ like other animals‚ it constantly perceives environmental cues and elicits appropriate physiological responses. Remarkably‚ this process is achieved with only a small number of neurons. An adult C. elegans hermaphrodite nervous system harbors 302 neurons‚ which have been grouped into 118 distinct classes according to their topology and synaptic connection pattern (Ward‚ 1975 #4;Sulston‚ 1977 #8;Sulston‚ 1983 #9;Ward
