How do biological organisms use energy worksheet answer key?

Biological Organisms and Energy Utilization

First, chemical energy from organic molecules is used to make ATP (Adenosine triphosphate) in cellular respiration, after which ATP provides energy for biological processes.

Answer:

Organisms use energy in two steps:

  • Conversion of food into adenosine triphosphate (ATP):

Organisms harness the chemical energy of the food and convert it into a more usable form, that is, ATP. The set of chemical reactions involved in this process is termed as cellular respiration. It may include glycolysis, Krebs cycle, electron transport chain, oxidative phosphorylation.

  • ATP hydrolysis:

Organisms use the energy associated with ATP through a hydrolysis reaction. The hydrolysis of ATP releases ADP, Pi, and energy. ADP is further hydrolyzed to produce AMP, Pi, and energy.

How do biological organisms utilize the chemical energy from organic molecules? Biological organisms utilize the chemical energy from organic molecules by converting them into adenosine triphosphate (ATP) through the process of cellular respiration. ATP then serves as the primary energy source for various biological processes within the organism.
