Question

Which of the following is the primary product of photosynthesis?

• A. Proteins
• B. Lipids
• C. Vitamins
• D. Carbohydrates

Hint:

Remember: Glucose (a carbohydrate) is the main output of photosynthesis — not proteins, lipids, or vitamins.

Answer 1

The Correct Option is D

Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy, usually from the sun, into chemical energy that can be used to fuel the organism's activities. The primary product formed through this process is carbohydrates.

The general equation for photosynthesis is:

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

In this reaction:

• Carbon dioxide (CO₂) and water (H₂O) are transformed into glucose (C₆H₁₂O₆), which is a simple carbohydrate.
• Oxygen (O₂) is released as a byproduct.

Among the options provided:

• Proteins are not primary products of photosynthesis; they are synthesized later using amino acids.
• Lipids are not directly produced through photosynthesis.
• Vitamins are not synthesized as a direct product of photosynthesis.
• Carbohydrates, specifically glucose, are the main initial product of photosynthesis, serving as an energy source for plants and other organisms.

Thus, the correct answer is Carbohydrates.
