The Light Independent Reactions (aka the Calvin Cycle)

Section Summary. Using the energy carriers formed in the first steps of photosynthesis, the light-independent reactions, or the Calvin cycle, take in CO 2 from the environment. An enzyme, RuBisCO, catalyzes a reaction with CO 2 and another molecule, RuBP. After three cycles, a three-carbon molecule of G3P leaves the cycle to become part of a carbohydrate molecule.

8.2 The Light-Dependent Reaction of Photosynthesis

The actual step that converts light energy into chemical energy takes place in a multiprotein complex called a photosystem, two types of which are found embedded in the thylakoid membrane, photosystem II (PSII) and photosystem I (PSI) (Figure 8.16). The two complexes differ on the basis of what they oxidize (that is, the source of the low

Light-Independent Reactions. After the energy from the sun is converted into chemical energy and temporarily stored in ATP and NADPH molecules (having lifespans of millionths of a second), photoautotrophs have the fuel needed to build multicarbon carbohydrate molecules, which can survive for hundreds of millions of years, for long-term energy storage.

2.5.3: The Light-Dependent Reactions of Photosynthesis

When a person turns on a lamp, electrical energy becomes light energy. Like all other forms of kinetic energy, light can travel, change form, and be harnessed to do work. In the case of photosynthesis, light energy is converted into chemical energy, which photoautotrophs use to build carbohydrate molecules (Figure (PageIndex{1})).

An average round trip energy efficiency of 22.6% was achieved.

5.2: The Light-Dependent Reactions of Photosynthesis

The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.

6 FAQs about [Summary of the light energy storage experiment]

How did Lenard explain the photoelectric effect?

1. Lenard's trigger hypothesis to explain the photoelectric effect (C1). Lenard made the important experimental determination that in photoelectric phenomena the velocity of the ejected electrons is independent of the intensity of light.

How long can a solid state device store light coherently?

A solid-state device can now store light coherently for up to one minute. Figure 1:(a) Energy-level scheme for EIT experiments: two ground states ( | g 〉 and | s 〉) are connected to one excited state ( | e 〉) by an optical transition. To reach the EIT condition, the frequency difference between the input and control beams must be equal to

What were Millikan's presuppositions about the nature of light?

5. Millikan's presuppositions about the nature of light (C5). Although Millikan provided the first experimental proof of Einstein's equation, he considered Einstein's interpretation of the photoelectric effect, based on the quantum hypothesis, as “the reckless, hypothesis” (Millikan, 1916b, p. 355).

How does light affect biochemistry?

As light increases, downstream biochemistry should become increasingly limiting. Because downstream energy storage and metabolic processes are likely to be more temperature dependent than photochemistry, this shift may allow us to distinguish between these types of limitations.

What are the limitations to the storage time in atomic gases?

The main limitation to the storage time in atomic gases is the random motion of the atoms, which causes dephasing of the spin waves. In 2013, the limitation was mitigated by placing the atoms in an optical lattice, limiting the atomic motion and allowing a storage time of 16 seconds (s) for classical pulses .

Are there any textbooks based on the photoelectric effect?

The analysis reveals that very few textbooks have the section on the photoelectric effect written from an overall HPS perspective. The two Hecht editions (1998 and 2003) come closest to the requirements. These editions include significant and accurate historical details that are accurately portrayed from the HPS perspective.
