Xeroderma Pigmentosum.
this is a rare pigmentary and atrophic autosomal recessive disease in which extreme cutaneous sensitivity to ultraviolet light results from an enzyme deficiancy in the repair of DNA damaged by ultraviolet light. it begins in childhood, with early development of excessive freckling, telangiectases, keratomas, papillomas, and malignancies in sun-exposed skin, severe opthalmologic abnormalities, and, in some cases, neurological disorders.
What else can I help you with?
What are the reactions of the first stage of the photosynthesis called?
This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions
The two major sets of reactions involved in photosynthesis are?
The two major sets of reactions involved in photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to produce ATP and NADPH, while in the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
Photosynthesis generates ATP and NADPH during what stages?
Photosynthesis generates ATP during the light-dependent reactions (photophosphorylation) and NADPH during the light-dependent reactions (photolysis of water and reduction of NADP+ to NADPH).
How much ATP is produced in the light-dependent reactions of photosynthesis?
In the light-dependent reactions of photosynthesis, approximately 18 molecules of ATP are produced for every 6 molecules of oxygen released.
What is the primary function of the light dependent reactions of photosynthesis?
The primary function of the light-dependent reactions in photosynthesis is to convert light energy into chemical energy in the form of ATP and NADPH, which are used in the light-independent reactions (Calvin cycle) to produce glucose. These reactions occur in the thylakoid membranes of chloroplasts and involve the splitting of water molecules to release oxygen as a byproduct.
What are the reactions of the first stage of the photosynthesis called?
This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions
What are the reactions in which light energy from the sun is converted to chemical energy called?
light-dependent reactions. such as photosynthesis in green plants.
The initial reactions in photosynthesis are know as the?
The initial reactions in photosynthesis are known as the light-dependent reactions. These reactions occur in the thylakoid membranes of the chloroplast and involve the absorption of light energy to drive the conversion of water into oxygen, ATP, and NADPH.
Are the reactions of photosynthesis?
There are two reactions. Those are light dependent and independent.
What are the stage in the process of photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
The two major sets of reactions involved in photosynthesis are?
The two major sets of reactions involved in photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to produce ATP and NADPH, while in the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
What are two stages in the process of of photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
The first process in the light-dependent reactions of photosynthesis is?
light absorption
Where are the light dependent reactions located?
The light-dependent reactions of photosynthesis take place in the thylakoid membranes of the chloroplasts. This is where sunlight is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH.
Photosynthesis generates ATP and NADPH during what stages?
Photosynthesis generates ATP during the light-dependent reactions (photophosphorylation) and NADPH during the light-dependent reactions (photolysis of water and reduction of NADP+ to NADPH).
What are gas of the light dependent reactions in photosynthesis?
Carbon Dioxide
What is released during the light dependent reactions of photosynthesis?
oxygen
