What happens to your enzymes when they get too hot? The enzymes denature and the active site alters, so the substrate can't fit in there properly and chemical reactions don't happen as fast.

The enzyme changes shape, but the substrate still fits in and the chemical reaction can still take place.

The enzyme dissolves and the pieces then need to be rebuilt before they can be used again.

Nothing, the enzyme can handle temperature changes in the body.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
