Question

4. What energy is needed by organisms during cell respiration?​

Answer 1

Adenosine Triphosphate(ATP) energy is needed by organisms during cell respiration.      

Explanation:  

Adenosine Triphosphate(ATP):

• Adenosine Triphosphate (ATP) is the primary energy carrier in all living organisms on earth. Microorganisms capture and store energy metabolized from food and light sources in the form of ATP.

• When the cell requires energy, ATP is broken down through hydrolysis. The high-energy bond is broken and a phosphoryl group is removed.

• The energy released from this process is used to drive various cellular processes.

• ATP is constantly formed and broken down as it participates in biological reactions and it is central to the health and growth of all life. Without it, cells could not transfer energy from one location to another, making it impossible for organisms to grow and reproduce!

Cell respiration:

• Heat and light are two forms of energy that are released when a fuel like wood is burned. The cells of living things also get energy by "burning." They "burn" glucose in the process called cellular respiration.

• Inside every cell of all living things, energy is needed to carry out life processes. Energy is required to break down and build up molecules and to transport many molecules across plasma membranes. All of life's work needs energy.
• A lot of energy is also simply lost to the environment as heat. The story of life is a story of energy flow - its capture, its change of form, its use for work, and its loss as heat.
• Energy, unlike matter, cannot be recycled, so organisms require a constant input of energy. Life runs on chemical energy.
