"Replication" MUST occur before mitosis and meiosis can occur. :)
Carbohydrates are an important type of FOOD MACRO MOLECULES.
Food macro molecules refers to the small chemical sub units of molecules which are found in food. There are four major food macro molecules, they are carbohydrates, proteins. lipids and nucleic acids.
Carbohydrate is an important source of fuel for the biological system.
Because the charge of electrons is opposite in sign than protons, the two types of particles attract each other, and this force, known as the Coulomb force, holds the atom together. Electrons travel around the nucleus in orbitals, but it is impossible to know both the speed and location of an electron at the same time.:) let me know if this helped
Answer:
Having a repetitive enzyme system would allow more than one enzyme to catalyze a particular reaction. If one of the types of enzyme is not able to perform its function due to temperature or any other factor, then another kind of enzyme would be able to catalyze the reaction. Hence, having repetitive enzyme systems is very effective in carrying out the metabolic functions of the body even when conditions are not favourable.
