Succinic acid is oxidised to fumaric acid by the removal of 2 hydrogen atoms. The reaction is catalysed by succinic acid dehydrogenase. The hydrogen atoms are accepted by FAD and it forms FADH 2..

John tossed a coin 20 times. The outcomes were: T, H, H, H, T, H, H, T, H, T, H, H, H, T, T, T, H, H, H, T. Which table represents the data? => Table 3 or Table 4 or Table 2 or Ta..

Nitrogen Molecule Nitrogen atom has five electrons in its valence shell. It requires three more electrons to acquire a stable configuration of the nearest noble gas (neon). This is done by mutually sharing three pairs of electrons as shown below. ..

Tracheids are elongated dead cells that have sloping end walls. The cavity is empty as the cells are dead. The walls are thickened with a material called lignin. These thickenings are in different patterns. The cells are arranged end to end. Vessels are also dead cells that have variously patt..

pH is the negative logarithm of H 3 O + ion concentration in moles/litre pH of water = 7 at 298 K pH of acids = less than 7 pH of bases = greater tha..

The pH Scale - The strength of acids and bases can be expressed in terms of the concentration of the hydronium ions or hydroxyl ions in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre of solution. This is expressed by a t..

Basic salts are stronger in their basic nature and show a pH greater than ..

During increased body activity the CO 2 content of blood raises. It combines with water to form carbonic acid in the blood. This lowers the pH, which increases the heart be..

When a substance is placed in an external magnetic field, the substance experiences a torque due to the field and aligns in the same direction as the field. The magnetisation so produced in the substance is called Induced magnetisation and strength of external field is called intensity of magnetis..

2 O) Water is a typical polar compound, which exhibits Hydrogen bonding. In addition to two (O-H) bonds in water, oxygen atoms form two hydrogen bonds. Consequently, four hydrogen atoms, two by covalent bonds and two by hydrogen bonds tetrahedrally surround each oxygen atom. The as..
