Terminal phosphate linkage means

Posted by Sangeeta Deendayal Tiwari 5 years, 6 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 5 months ago

ATP is made unstable by the three adjacent negative charges in its phosphate tail, which "want" very badly to get further away from each other. The bonds between the phosphate groups are called phosphoanhydride bonds, and you may hear them referred to as “high-energy” bonds. ATP is formed of adenine, ribose and a row of three phosphate radicals attached to ribose. The last two phosphate radicals are attached by bonds of high transfer potential. This bond is also known as terminal phosphate linkage. This bond can be very easily synthesised and broken up. ATP is the higher energy form (the recharged battery) while ADP is the lower energy form (the used battery). When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.

Raman Upadhyay 5 years, 6 months ago

Corrosion can be prevented by removing one of these conditions. Coating a metal surface with paint or enamel provides a barrier between the metal and the moisture in the environment. The process of coating a metal surface with another metal that is more likely to be oxidized is referred to as sacrificial coating.

Tanisha ?? 5 years, 6 months ago

1. There was a regular gradation in physical and chemical properties of elements. 2. The group number of an element indicates highest oxidation state that it can attain. 3. There were many vacant spaces in Mendeleev's periodic table for the elements to be discovered. He named them Eka-Boron, Eka-Aluminium and Eka-silicone He also predicted the properties of these undiscovered elements including atomic masses. These elements were discovered as Sc ,Ga and Ge with same features as he predicted. 4. Mendeleev’s arrangement helped to correct atomic masses of a number of elements.

Why burning of wax is chemical change

Posted by Saba Fatima 5 years, 6 months ago

CBSE > Class 10 > Science

1 answers

Chandrashekhar Bhosle 5 years, 6 months ago

Burning is a chemical change that involves oxidation thus producing heat and light. When a candle is burnt in air, the mass of the product is increased due to atmospheric oxygen which combines with the carbon and hydrogen of the candle wax during burning to produce water vapour and carbon dioxide. Also, the original properties of the reactants are altered. All these factors prove that the burning of a candle is a chemical change.

Interneuron refer to any neuron that acts as an intermediary in passing signals between two other neurons. Interneurons do not have a motor or sensory functions; they just act to pass on information. Interneuron receives information from both external (through the senses) and internal (from muscles, organs and glands) environment. Interneuron. only located in CNS & connect between motor and sensory neurons. -Exist only in the central nervous system (brain and spinal cord). The nerve cells of the central nervous system are all interneurons. The interneurons receive impulses from the sensory neurons. They interpret the information received from other neurons and relay impulses to motor neurons for an appropriate response.

Posted by Kk Kk 5 years, 6 months ago

CBSE > Class 10 > Science

1 answers

Yogita Ingle 5 years, 6 months ago

Calvin cycle is also known as C3 cycle or light-independent or dark reaction of photosynthesis. However, it is most active during the day when NADPH and ATP are abundant. To build organic molecules, the plant cells use raw materials provided by the light reactions:

1. Energy: ATP provided by cyclic and noncyclic photophosphorylation, which drives the endergonic reactions.

2. Reducing power: NADPH provided by photosystem I is the source of hydrogen and the energetic electrons required to bind them to carbon atoms. Much of the light energy captured during photosynthesis ends up in the energy-rich C—H bonds of sugars.
