explain how the metabolic processes of cellular respiration and photosythesis recycle oxygen?

Question

if u could reccomend a website with this information it would be great too

Answer 1

Cellular respiration is a process that describes the metabolic reactions and processes that take place in a cell to obtain chemical energy from fuel molecules. Energy is released by the oxidation of fuel molecules and is stored as "high-energy" carriers. The reactions involved in respiration are catabolic reactions in metabolism.

Fuel molecules commonly used by cells in respiration include glucose, amino acids and fatty acids, and a common oxidizing agent (electron acceptor) is molecular oxygen (O2). There are organisms, however, that can respire using other organic molecules as electron acceptors instead of oxygen. Organisms that use oxygen as a final electron acceptor in respiration are described as aerobic, while those that do not are referred to as anaerobic.

The energy released in respiration is used to synthesise molecules that act as a chemical storage of this energy. One of the most widely used compounds in a cell is adenosine triphosphate (ATP) and its stored chemical energy can be used for many processes requiring energy, including biosynthesis, locomotion or transportation of molecules across cell membranes. Because of its ubiquitous nature, ATP is also known as the "universal energy currency", since the amount of it in a cell indicates how much energy is available for energy-consuming processes.

Now, do your own homework!!!

Answer 2

In photosynthesis, oxygen is a waste product. That is, when carbon dioxide is converted into carbohydrates by photosynthetic organisms, oxygen is released.

Aerobic organisms then convert carbohydrates back into carbon dioxide by reacting them with oxygen to produce CO2 and water.

I think if you just google "photosynthesis respiration oxygen" you'll probably find some diagrams that would illustrate this.
