Summary Introduction

Introduction: The process of conversion of light energy to chemical energy occurs in two phases of reactions, that is light-dependent reaction and light-independent reaction. In photosynthesis, the two photosystems absorb the light which in turn stimulates an electron molecule to a higher energy state, by transforming the energy of sunlight to chemical energy.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: The chemical that functions as an energy-carrying molecule in all organisms is ATP.

Hence the correct answer is option d.

Explanation of Solution

Reason for correct answer:

Adenosine triphosphate (ATP) is the energy-carrying molecule present in the cells of all living organisms. It is produced from the light reaction, which is utilized in the Calvin–Benson cycle. It provides chemical energy for the production of sugar. ATP captures the chemical energy acquired from the breakdown of food molecules and releases it to fuel other cellular processes.

Option d. is given as “ATP”.

ATP is the energy-carrying molecule in all organisms.

Hence, the correct answer is option d.

Reason for incorrect answer:

Option a. is given as “carbon dioxide”.

In photosynthesis process, carbon dioxide (CO₂) and water (H₂O) in the presence of light energy give sugar and oxygen (O₂). CO₂is not the energy source in photosynthesis.

Hence, option a. is incorrect.

Option b. is given as “water”.

In photosynthesis process, carbon dioxide (CO₂) and water (H₂O) in the presence of light energy give sugar and oxygen (O₂). H₂O is not the energy source in photosynthesis.

Hence, option c. is incorrect.

Option c. is given as “RuBP”.

During the carbon fixation step of the Calvin–Benson cycle, the atmospheric carbon dioxide molecule combines with three molecules of a five-carbon compound Ribulose 1, 5-bisphosphate (RuBP) to form six molecules of a three-carbon compound 3-Phosphoglycerate that is catalyzed by the enzyme RuBisCO (Ribulose-1, 5-bisphosphate carboxylase/oxygenase). RuBP is not the energy source in photosynthesis.

Hence, option c. is incorrect.

Hence, options a., b., and c. are incorrect.

Conclusion

ATP is the energy-carrying molecule which is found in all living organisms.
