Answer:

The independent reactions of light can be called dark phase and chemical phase. This phase occurs in the chloroplast stroma.

Explanation:

The Dark Phase is also called the chemical phase and the light independent phase. But, despite receiving these names, it is a phase of photosynthesis that indirectly depends on light. So it happens, therefore, for the Calvin cycle to occur, the chloroplast needs the products released at the end of the clear phase of photosynthesis: ATP and NADPH.

So, don't get confused: the dark phase does not occur without the presence of light, such as during the night. Since ATP and NADPH are very unstable, the dark phase must occur concurrently with the light phase.

During the independent phase of light or chemistry, which happens in the chloroplast stroma, the process that we call carbon fixation will take place. In fixing the carbon, the carbon present in the carbon dioxide molecule (which was captured by the plant's stomata, in the case of the kingdom plants) will be reorganized to form energetic organic molecules, whose bases are carbon chains, such as glucose.

son4ous [18]
The law of entropy, presence of water, physical conditions of earth movement like volcanoes and atmospheric effects, and the stochastic, random interaction of elements on the Earth determined the degree of molecular assembly possible. The simple abiotic chemicals found in the water, on the land or distributed in the air, and deposited from meteors and comets show that at most some elemental biochemicals, including amino acids, simple sugars, lipids and polymers could form.

There are no naturalistic conditions or processes that could produce all the biochemical compounds and molecules required to assemble even the simplest living organism. Even in the lab, highly intelligent design and management of experiment processes and materials is required to produce interesting, but relatively minor, complex assemblies, but nothing  comprehensive.

The statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.

<h3>What is Calvin cycle?</h3>

Calvin cycle of photosynthesis is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms.

The Calvin cycle also called light independent or dark reaction is the second stage of the photosynthetic process. It is so called because it does not require light to occur.

The Calvin cycle makes use of the products of the light stage (ATP and NADPH) to synthesize carbohydrates.

However, the series of reaction is an energy consuming one, which makes use of ATP to occur.

Therefore, the statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.
