Question

How do biological organisms use energy worksheet answer key?

Answer 1

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 more usable for 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.

Answer 2

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