Explanation:
Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Answer:
The atomic number is 79 and the atomic mass is 197.
Explanation:
The atomic number (symbol Z) of a chemical element is the number of protons within its nucleus.
Gold (chemical symbol Au) is a chemical element with 79 protons in its nucleus, therefore with atomic number 79.
The atomic mass is the average mass of the atoms of an element (in atomic mass unit). The atomic mass is the weighted average of all the isotopes of a a particular element. For each isotope the atomic mass is approximately the mass of both protons and neutrons since electrons make minor contributions.
The atomic mass of Gold (Au) is 196.9665 but, it can be rounded to 197.
The white bread will mold the slowest because there is less density
Nerve cells communicate by sending an electrical signal through an axon, from this molecules get released into the synapse this then binds itself onto receptor sites. With ion-linked channel receptors, the ligands get binded to a protein. The ion channels are then opened and the proccess gets repeated. Does that help?
