Which of these equations best summarizes photosynthesis?

A: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy

B: C6H12O6 + 6 O2 → 6 CO2 + 12 H2O

C: 6 CO2 + 6 H2O → C6H12O6 + 6 O2

D: 6 CO2 + 6 O2 → C6H12O6 + 6 H2O

E: H2O → 2 H+ + 1/2 O2 + 2e-

Answer:

C: 6 CO2 + 6 H2O → C6H12O6 + 6 O2

Photosynthesis:

The process in which green plants and other organisms convert sunlight into chemical energy is called photosynthesis.

In photosynthesis, green plants absorb light energy and convert it into carbon dioxide, water. It turns minerals into oxygen and energy-rich organic compounds.

The reaction of photosynthesis:

Photosynthesis is an oxidation-reduction process. In plants, light energy is used for the oxidation of water from which hydrogen ion (H+), oxygen gas (O2), and electrons are produced.

Which of these equations best summarizes photosynthesis?

Most of the hydrogen ions and electrons are converted into carbon dioxide, which is reduced to organic products. Other hydrogen ions and electrons are used to convert sulfate and nitrate into amino acids and sulfhydryl groups in amino acids. These are building blocks of proteins.

In green plants, carbohydrates such as starch, sugar, and sucrose are the direct product of photosynthesis.

The following equation can represent the overall reaction of photosynthesis in which carbohydrates (CH2O) are formed:

As it is stated above that carbohydrates are the essential organic product of photosynthesis, the formation of glucose can be expressed in the following chemical reaction.

The above chemical reaction indicated that six molecules o carbon dioxide and 12 molecules of water combine in the presence of sunlight and produces six molecules of oxygen and water, and one molecule of glucose.
