what is another name for the light independent phase of photosynthesis?
30488
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.

Photosynthesis occurs only in the light, and cellular respiration occurs only in the dark.

Photosynthesis in the leaves of plants involves many steps, but it can be divided into two stages: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy.

Photosynthesis is a multi-step process that requires sunlight, carbon dioxide, and water as substrates. It produces oxygen and glyceraldehyde-3-phosphate (G3P or GA3P), simple carbohydrate molecules that are high in energy and can subsequently be converted into glucose, sucrose, or other sugar molecules.

NADPH formation. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.

Photosynthesis in plants can be described in four stages, which occur in specific parts of the chloroplast. In stage 1, light is absorbed by chlorophyll a molecules bound to reaction-center proteins in the thylakoid membrane.

The dark reaction of photosynthesis is not dependent on sunlight but it does not mean it does not occur in its presence. The dark reaction occurs both in the presence and absence of sunlight. This reaction occurs in the stroma of the chloroplasts which are cell organelles known as the kitchen of the cells.

The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.

1) There are two major phases found in photosynthesis. They are light reaction and dark reaction. 2) Light reaction : The light reaction takes place in chlorophyll containing thylakoids called grana of chloroplasts. 3) The chlorophyll on exposure to light energy becomes activated by absorbing photons.

Answer 1: Photosynthesis is light dependent. At low light intensities, light is a limiting factor for photosynthesis. The rate of photosynthesis to the light intensity is inversely proportional, so it will increase rapidly at first the levels off until it reaches its optimum speed.

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2. ... During this process, organisms such as plants go through the light-dependent and light-independent reactions to convert carbon dioxide and water into sugars and oxygen.
1253626
The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP.
325206
In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide. ... Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
380095
The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

And when the response is away from the source of light, it is called negative phototropism. For example, we see plants bending towards sunlight. It is actually their response towards light and is called positive phototropism. While, the response of plants towards gravity is called gravitropism or geotropism.
