The "light dependent phase" or "light-dependent reaction" is a phase in photosynthesis in which light is absorbed by the photosystems (PS I and PS II) in the thylakoid membranes and electrons flow through the electron transport chains.
light dependent phase happens as :
When the chloroplasts are exposed to light , some electrons in the atoms of the chlorophyll molecule gain energy , these electrons jump up & light energy is converted into kinetic energy , energy then is stored in form of potential chemical energy , electrons release the stored energy & thus they return to original energy levels part of released energy is stored in the form of ATP , other part is used in splitting H2O into hydrogen & oxygen
A phase in which light is not necessary. Depending on the context it may be for chemical reactions.
why is there a light dependent phase and why is there a light independent (dark) independent phase
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
For the light dependent phase of photosynthesis all you need is sunlight and water as the inputs. The output is pure hydrogen (H+, protons) and oxygen. The protons are in the form of a hydrogen gradient, which is converted to ATP by the ATPase enzyme. Water is important because it provides the electrons lost when the sunlight is converted to chemical energy. The products after water is 'split' are the protons previously mentioned and oxygen.
light independent It does not need light energy directly.It uses light energy captured in light reaction
light dependent
The initial stage of [[photosynthesis in [[chlorophyll Molecules where the presence of [[light Energy raises the energy. It is the first event int he first phase of photosynthesis which is light-dependent reactions.it happens at the thykaloid. Chlorophyll molecules capture light energy and becomes energized electrons(e-).
light independent phase and light dependent phase
It is the first phase. The light dependent reaction.
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
2 the light dependent phase and the Calvin Cycle
oxygen, glucose, and carbon monoxide.
The phases where light energy is converted into ATP are called light reactions. I don't know if you want information on what happens then or not, though.
All phase specific types are by definition cell cycle specific? But does it work the other way around? (i.e. are there any types that are only cell cycle specific but not phase dependent?) Would like to now about the four main types of chemo. Alkylating agents - cell cycle independent Mitotic inhibitors - phase dependent? Topoisomerase inhibitors - both phase dependent and/or cell cycle dependent? Antimetabolites - phase specific?
The process is known as photosynthesis. It is the single most important metabolic reaction in the universe and essential to most living organisms.The reaction comprises two parts. The Light Dependent phase and the Light Independent phase, also known as the Calvin Cycle.
Light-dependent reactions are those that require light to proceed.
Glencoe Science; BIOLOGYLight energy is absorbed and then converted into chemical energy in the form ofATP and NADPH. The ATP and NADPH that were formed in phase one are usedto make glucose.
It is well known that photoperiodism is largely responsible for flowering. The initiation of reproductive phase is a light dependent phenomenon in majority of plants.
