Question

Photosynthesis is an example of
A. Anabolism
B. Endergonic reactions
C. Both A and B
D. Exergonic reactions

Answer 1

Hint: Plants are experimentally known as autotrophs because they are converting energy into chemical energy. The word photosynthesis is a combination of two words that is photo means light and synthesis means combining. The plants make glucose by utilizing water, light, and the gases present in the air. In this process, oxygen is produced as a byproduct.

Complete answer: Photosynthesis is the cycle by which green plants and certain different life forms produce light energy into chemical energy. Photosynthesis is done differently by different species, the process always initiates when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are carried by chloroplasts inside organelles called chloroplasts, which are most extensive in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to extract electrons from appropriate substances, such as water, which creates oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to operate other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), the “energy currency” of cells.
In plants, algae, and cyanobacteria, long term energy storage in the form of sugars is produced by a sequence of light-independent reactions called the Calvin cycle; some bacteria use different mechanisms, such as the Krebs loop inverted, to match the same goal. Atmospheric carbon dioxide is interspersed with existing organic carbon compounds, such as ribulose bisphosphate, in the Calvin Cycle (RuBP). Using ATP and NADH produced by light-dependent reactions, the remnants of carbon dioxide are interspersed.
Thus, the answer is option C: Both A and B

Note: Photosynthesis happens in the carbon dioxide created by every single breathing living being also, once again introduces oxygen into the air. Photosynthesis is the cycle that is utilized by plants, green growth, and certain microbes to tie energy from daylight and transform it into synthetic energy.
