The Balanced chemical equation for above reaction will be :

The Coefficients will be :
So, Correct option is :
A. 3, 1, 1, 3
_____________________________

There are several units for expressing energy, Most common are joules and kilocalories.
The conversion factor of joule to kilocalories is
1 kilo calorie = 4184 J
∴ x kilo calorie = 256 J
x =

kilo calories
Thus, 256 J = 0.0611 kilocalories

Answer:
The enzyme's active site must be the mold shape of the substrate.
Explanation:
An enzyme and a substrate bind together in order to work. If the shapes of the 2 are different, they will not be able to bond together. If the shapes of the 2 fit glove-in-hand, then they will be able to bond together.
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom(which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. Most of an atom is empty space.
