which of the following Is not a cell activity powered by energy produced through cellular respiration? 1. Division 2. Growth 3.
harina [27]

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.

Why the membrane potential is negative, if there is a higher concentration of positive ions inside the cell than outside (counte
Nina [5.8K]

Answer:

Net membrane potential is equal to the difference of positive charge and negative charge existing at the inner and outer side of the cell respectively. Since outer negative charge is higher in concentration, the net membrane potential is negative

Explanation:

The cell membrane potential defined as the net difference of ion concentration existing at the inner and outer side of a cell membrane at nay instance.  

When the cell is at the resting potential, the positive potassium ion starts accumulating at the inner surface of the cell membrane as it becomes favors positive potassium ion. This leads to development of negative potential at the outer side of cell membrane by the accumulation of negative ions or charges. Hence, a net negative potential membrane develops.
