PHOTOSYNTHESIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following formulas represents photosynthesis?
A
6 H2O + 6 O2 = C6H12O6 + 6 CO2
B
6 H2O + 6 CO2 = C6H12O6 + 6 O2
C
C6H12O6 + + 6 O2 = 6 H2O + 6 CO2
D
None of the above
Explanation: 

Detailed explanation-1: -The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Detailed explanation-2: -The equation represent the process of aerobic respiration.

Detailed explanation-3: -Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.

Detailed explanation-4: -The chemical reaction for photosynthesis is:6CO2 + 6H2O → C6H12O6 + 6O2. The chemical reaction for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O.

Detailed explanation-5: -oxidation reaction is : C6H12O6 + 6O2-> 6CO2 + 6H2O. Yields 2755 kJ/mole of glucose. The reverse of this reaction – combing carbon dioxide and water to make sugar – is known as photosynthesis. Photosynthesis is the process responsible for storing all the energy we extract from fossil fuels, crops, and all of our food.
