The activity of the cell that is not powered by the energy produced through cellular respiration is passive transport.
The cell is the smallest unit of an organism. A cell is self sufficient. Cells obtain energy for their activities via cellular respiration. This is the breakdown of glucose to produce energy.
Passive transport is the movement of solute across the cell membrane without requiring energy for the process. Therefore, it does not require energy produced during cellular respiration.
Absolute brightness represents
the total amount of energy emitted from a celestial object. It is the measure
of the true brightness of a star or other celestial object as it would be as
seen from a standard distance<span> of
exactly 10 parsecs (32.6 light-yea</span>rs). The more luminous an object, the smaller the
numerical value of its absolute magnitude or brightness.
