Question

The overall process of photosynthesis involves using sunlight in the conversion of carbon dioxide and water into which products?
A. ATP and oxygen
B. Oxygen and carbon
C. ATP and sugars
D. Sugars and proteins
E. Sugars and oxygen

Answer 1

Hint: Photosynthesis is the process that occurs in chloroplasts by photosynthetic pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll. All green plants and a few other autotrophic organisms use photosynthesis to synthesize nutrients by using carbon dioxide, water and sunlight. It produces and organic molecule with gas as the byproduct.

Complete step by step answer: Green plants capture solar energy and convert it into chemical energy by the process called photosynthesis. It is an anabolic process of manufacturing organic compounds. It is characterized by the reduction of carbon dioxide and oxidation of water. During photosynthesis, carbon dioxide and water molecules are transformed into simple carbohydrates, and oxygen is liberated into the atmosphere. Carbon dioxide + Water = Glucose + oxygen. Photosynthesis also occurs in other organisms besides green plants. These contain several types of prokaryotes such as cyanobacteria, purple bacteria and green sulfur bacteria. These organisms exhibit photosynthesis like green plants. The glucose made during photosynthesis is then used to fuel various types of cellular activities. The by-product of this physio-chemical process is oxygen. Photosynthesis is also utilized by algae to convert solar energy into chemical energy. Oxygen is liberated as a derivative and light is considered as a huge factor to complete the process of photosynthesis.
Hence, the correct answer is option E.

Note: Photosynthesis is considered to be an endothermic reaction. Photosynthesis takes place when plants use light energy to convert carbon dioxide and water into glucose and oxygen. Leaves contain microscopic cellular organelles called chloroplasts where this process occur. It involves light-dependent and light-independent reactions.
