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.
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 main energy-storing product of the light-dependent phase of photosynthesis is ATP (adenosine triphosphate) and NADPH. In the light-independent phase, the main energy-storing product is glucose.
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.
In the second phase of photosynthesis, known as the light-independent reactions or the Calvin cycle, carbon dioxide is converted into glucose using the energy stored from the light-dependent reactions. This process takes place in the stroma of the chloroplasts and does not require light to occur.
The light-independent reactions occur in the storm of the chloroplast. The light- independent reactions are "independent" from light so they can happen else where. The light-dependent reactions happen in the thylakoid membrane of the chloroplast where the light is absorbed, and the reactions depend on the light.
It is the first phase. The light dependent reaction.
Photosynthesis occurs in two main steps: light-dependent reactions and light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to split water and produce ATP and NADPH. In the light-independent reactions, ATP and NADPH are used to convert carbon dioxide into glucose.
The light-dependent phase of photosynthesis occurs in the thylakoid membranes of the chloroplasts in plant cells. During this phase, light energy is absorbed by chlorophyll and used to convert water and sunlight into ATP and NADPH, while releasing oxygen as a byproduct. This process is essential for capturing energy that will be used in the subsequent light-independent phase, or Calvin cycle, which takes place in the stroma of the chloroplasts.

No, chlorophyll is not needed during the dark phase of photosynthesis. Chlorophyll is a pigment that absorbs light energy to drive the light-dependent reactions of photosynthesis, which only occur during the light phase. In the dark phase (or light-independent phase), known as the Calvin cycle, chemical reactions use ATP and NADPH produced during the light phase to convert carbon dioxide into glucose.
In the second phase of photosynthesis, known as the light-independent reactions or the Calvin cycle, carbon dioxide is converted into glucose using the energy stored from the light-dependent reactions. This process takes place in the stroma of the chloroplasts and does not require light to occur.
The first phase of photosynthesis is the light-dependent reactions, which occur in the thylakoid membranes of chloroplasts. In this phase, light energy is captured and used to split water molecules into oxygen, protons, and electrons.
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?
