What is ATP and its Function
ATP means Adenosine tri-phosphate. Its uses are as under:
- i) It is used in synthesis of various compounds like carbohydrates, fats and proteins etc.
- ii) It is used in carrying out any physical work like muscle contraction.
Composition:
It is made up of three-phosphate group. Adenosine is formed of nitrogenous base (adenine) and sugar (ribose). In ATP three-phosphate group are attached in series.
Uses:
The bond between phosphate groups contain a large amount of chemical energy. When these bonds are broken down a large amount of energy is released which is used in different activities of organism.
Different Methods of Respiration
There are two types of methods of respiration:
Anaerobic respiration:
Some organisms oxidize their food without using any molecular oxygen. This is known as anaerobic respiration. In this process less energy is produced. It is also called fermentation.
Aerobic respiration:
In higher organisms energy is produced using molecular oxygen. This is known as aerobic respiration. In this method large quantity of energy is produced.
Note: Is it worth it to study abroad or does it make no sense? What do foreign universities give, what opportunities are open to students? And are there any opportunities or is it just a screen to attract more students and advertise? The pros and cons of studying abroad will be discussed in the article. Study abroad is very attractive. Some eminent universities not only invite foreign students, but also provide free education opportunities, which is difficult to achieve even in their native country! Expansion of connections, acquaintances, and in-depth study of another country and its language will not prevent any person who wants to achieve something in life. Today it is not difficult to enter a foreign university, but not all students of foreign institutions respond positively to them. Yet study abroad is associated with many difficulties. Not everyone can cope with such a problem. European education is valued all over the world . If a person graduated from a European university, we can assume that his future is secured. Finding a good job, entering any institution will not be a big deal for him. If desired, he can even work in another country.
