it is broken down to fuel chemical reactions & is created by chemical reactions.
The valence electrons are the part that takes place in a chemical reaction.
No, absolutely not. There are much smaller particles, first Electrons (which are part of reactions), Then Quarks that neutrons and protons are made of (and are part of reactions), and much, much smaller particles after that also are involved in chemical reactions.

It takes place in middle part. It is called stroma
Covalent bonds can be formed because of chemical reactions.

Most chemical reactions take place in the cytoplasm.

ENZYMES!!
enzymes
Cells need water to dissolve many of the chemical components of the cell. They need to have a precise range of concentration in order to function properly. They also need water in chemical reactions called hydrolysis reactions. In these reactions, chemical compounds are broken down by the addition of water.
The electrons
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
