Answer:

C. 11 protons, 11 electrons, 12 neutrons

Explanation:

Sodium is an alkali metal whose symbol is Na and atomic number 11. It is highly reactive metal as it is ready to donate a single electron which is present in its outer shell. In each sodium (Na) atom there is 11 protons and 12 neutrons as its atomic mass is 23 (11+12) and number of electrons will be 11 in a neutal sodium atom.

Which statement best describes enzymes?
Nuetrik [128]

Answer:

The rate of activity of an enzyme might change as pH changes

Explanation:

Enzymes are organic catalysts that controls the rate of a specific chemical reaction.

These materials combines substrates in order to lower the activation energy which might serves as a barrier to chemical action.

  • Enzymes have specific reactions which they control.
  • Temperature and PH conditions control the rate at which enzymes work.
  • They are not all produced from the building block of carbohydrates.
