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.

∙ 12y agolight 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

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 inputs are needed for and what products are made by the light dependent phase of photosynthesis?
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.
Is Calvin cycle light dependent or light independent?
light independent It does not need light energy directly.It uses light energy captured in light reaction
During the first stage of photosynthesis what is absorbed by chlorophyll?
light dependent
What is photoactivation of chlorophyll?
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-).
Photosynthesis occurs in two steps which are?
light independent phase and light dependent phase
What is the primary reaction in photosynthesis?
It is the first phase. The light dependent reaction.
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
How many reactions take place in photosynthesis?
2 the light dependent phase and the Calvin Cycle
What are the materials needed to be performed in the light dependent phase of photosynthesis so that product during the same phase will be performed?
oxygen, glucose, and carbon monoxide.
Phase of photosynthesis where light energy is converted to chemical in form of ATP?
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.
Can chemotherapy be cell cycle dependent but not phase specific (ex. pls)?
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?
Which is the process by which plants convert light into chemical energy?
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.
What are light light dependent reactions?
Light-dependent reactions are those that require light to proceed.
The energy acquired in the light-dependent reaction is used in the light-independent reaction to build glucose molecule show is this energy transferred from light-dependent to light-independent react?
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.
How does sunlight affect plant reproduction?
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.
What phase of the hydrologic cycle is dependent on plants?
transpiration
