Question

Put the following compounds in order from the first made during calvin

Answer 1

In the Calvin cycle, RuBP is first, followed by 3-PGA, then G3P. This cycle converts CO2 into glucose and other carbohydrates.

The Calvin cycle, also known as the light-independent reactions of photosynthesis, is a crucial process for converting carbon dioxide into glucose. It involves three main stages:

1. Carbon fixation: RuBP (ribulose 1,5-bisphosphate) is the first molecule involved in the Calvin cycle. It combines with CO2 to form two molecules of 3-PGA (3-phosphoglyceric acid). This reaction is catalyzed by the enzyme RuBisCO.
2. Reduction: 3-PGA is then converted to G3P (glyceraldehyde 3-phosphate) using ATP and NADPH. This reduction process requires energy from the light-dependent reactions of photosynthesis.
3. Regeneration: Some of the G3P molecules are used to synthesize glucose and other carbohydrates. However, some G3P molecules are also used to regenerate RuBP, ensuring that the cycle can continue.

Therefore, the order of the compounds made during the Calvin cycle is RuBP, 3-PGA, G3P.
