Describe photosynthesis like the reactants involves and what

Describe photosynthesis (like the reactants involves and what happens to the energy and oxygen produced) Do the same for cellular respiration (reactants involved and how they get into the animal and what happens to the energy and carbon dioxide produced). If one of these process stopped occurring what would happen?

Solution

Photosynthesis is a process in which plants and other living organisms convert light energy into chemical energy and prepare their own food materials. This chemical energy is stored in carbohydrate molecules, such as sugars synthesized from carbon dioxide and water, oxygen is released as a waste product.

6CO₂   + 6H₂0 ----------------> C₆H₁₂O₆ + 6O₂

Carbondioxide. Water. Light. Sugar. Oxygen

Splitting of water molecules leads to the production of two compounds that act as an intermediate energy storage means - NADPH & ATP termed as energy currency of cells. Using these ATP and NADPH produced the compounds are reduced and removed to form further carbohydrates, like glucose.

Cellular respiration is the process of oxidizing food molecules like glucose to carbon dioxide and water. The energy released is trapped in the form of ATP for the use of all energy consuming activities of the cell. This process occurs in 2 phases: glycolysis ( breakdown of glucose to Pyruvic acid)

Oxidation of pyruvic acid to carbon dioxide and water.

C₆H₁₂O_6.   +. 6O₂ ------------>. 6CO₂. +. 6 H₂O +. 38 ATP

If photosynthesis stops happening, all the organisms that require oxygen for aerobic cellular respiration cannot survive. Only anaerobic organisms survive. Cellular respiration stops after glycolysis when no oxygen is present.
