PHOTOSYNTHESIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The chemical reaction of ____ uses carbon dioxide gas from the atmosphere and the energy carried by ATP and NADPH to make simple sugars.
A
light-dependent reaction
B
Krebs cycle
C
Calvin cycle
D
photosynthesis
Explanation: 

Detailed explanation-1: -The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

Detailed explanation-2: -In the Calvin cycle, carbon dioxide (CO2) molecules are fixed to sugar with the help of an enzyme called RuBisCO. RuBisCO is short for ribulose-1, 5-biphosphate carboxylase/oxygenase. It is the most abundant protein on Earth.

Detailed explanation-3: -Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air. Eukaryotic autotrophs, such as plants and algae, have organelles called chloroplasts in which photosynthesis takes place.
