which of the following Is not a cell activity powered by energy produced through cellular respiration? 1. Division 2. Growth 3.
Zarrin [17]

Of the options listed, we can confirm that passive transport is not a cellular activity that is powered by the energy received through cellular respiration.

Cellular respiration is a process that produces much of the energy needed and used by a cell. The production of this energy is in the form of a molecule known as ATP. This ATP molecule is responsible for powering the growth of cells by acting as the substrate for most of the metabolic reactions present, as well as powering cellular division and repair.

The only option listed that is not powered by the use of ATP generated through cellular respiration, <em><u>or any other energy-generating method</u></em>, is passive transport. In order to move substances in and out of a cell, transport methods are used. These methods can be:

  1. Active transports
  2. Passive transports

Active and passive transports differ in one specific way. Passive transports do not consume energy, whereas active transports do. Therefore, since passive transports use chemical gradients which are natural processes that<u> do not use </u><u>energy</u><u>,</u> it will have no need for the ATP of the cell, and therefore the <u>correct answer</u> is "<em><u>4. Passive Transport</u></em>"
