Question

What is the formula for cellular respiration and photosynthesis?

Answer 1

Hint: A process by which animals take in oxygen and take out carbon dioxide to perform necessary functions essential for living is known as respiration. The process by which plants make their food by using both abiotic and biotic substances present in the environment to obtain energy and perform necessary functions for survival is known as photosynthesis.

Complete answer:
Photosynthesis and respiration are both very essential processes for plants and animals to survive. Photosynthesis is involved in the production of ATP by making glucose from inorganic materials. It uses light from sunlight, Carbon dioxide from the atmosphere, green pigment chlorophyll, and water extracted from the soil. Plants have photosystems I and II that are involved in an electron transport chain. The sunlight activates the photosystems and helps in splitting carbon dioxide and water into molecules of carbon, hydrogen, and oxygen through a series of light and dark reactions. All the molecules combine to form glucose molecules and oxygen is released as a by-product. The equation of photosynthesis is:

In cellular respiration, oxygen and water molecules are required to break down six-carbon glucose molecules into three-carbon pyruvate molecules to provide ATP. This is a ten-step process known as glycolysis. After glycolysis, pyruvate undergoes the Krebs cycle to produce hydrogen atoms and generate ATP. These free electrons establish an electron potential. The proton motive force drives them through is electron potential which generates a high amount of ATP and combines with nascent oxygen molecules to give out water. Cellular respiration releases carbon dioxide into the atmosphere. The equation of cellular respiration is:

Note:
The carbon cycle is defined as the pathways through which carbon is recycled out of the atmosphere. Photosynthesis and cellular respiration are two very essential parts of the carbon cycle. Cellular respiration releases carbon dioxide out in the atmosphere while photosynthesis absorbs this carbon dioxide from the atmosphere.
