Answer:

d. Electrons have a negative charge and are lighter than protons

Explanation:

The best statement that describes electrons is that electrons are negatively charged and are lighter than protons.

There are three known subatomic particles which are:

  • Protons which are the positively charged particles within an atom.
  • Electrons are the negatively charged particles
  • Neutrons do not carry any charges.

The mass of the protons and neutrons are similar.

Electrons are lighter than both protons and neutrons.

zloy xaker [14]

Answer:

Explanation:

In one of the process, energy is built up from scratch, in the other one, energy is liberated for use by an organism or body.

The first process deals with a metabolic reaction in which energy is liberated:

         C₆H₁₂O₆ + 6O₂  → 6CO₂ + 6H₂O + energy

In the above process, energy is liberated when glucose combines with oxygen. The waste products are carbon dioxide and water. This process liberates heat energy which can be used to do work.

   In the reverse process:

             6CO₂ + 6H₂O   →  C₆H₁₂O₆ + 6O₂

    This process stores energy in carbon chains as chemical energy. It is this energy that is released in the first process.

Therefore, we can see that the first process liberates energy and the reverse process stores energy.
