1. light energy from the sun hits the thylakoid membrane (of chloroplast), exciting the chlorophyll molecules in photosystem 1 and photosystem 2
2. excited electrons from photosystem 1 drive down the thylakoid membrane and create NADPH from NADP+
3. excited electrons from photosystem 2 drive down the membrane and pull H+ ions into the intermembrane space, these electrons replenish photosystem 1
4. The splitting of H2O forms oxygen gas, which replenishes the electrons from photosystem 2
5. The H+ ions in the intermembrane space have a lot of potential energy, so they go through ATP Synthase- which binds ADP and 1 phosphate to make ATP
The NADPH and ATP formed go on to the Calvin Cycle in the stroma.
What else can I help you with?
What are two phrases in photosynthesis?
There are two steps. Light dependent and light independant reactions
What are the two basic steps to photosynthesis?
The Light Dependent process and then the Light Independent process (known as the Calvin Cycle).
Photosynthesis occurs in two steps which are?
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.
What are the two different reaction of photosynthesis and explain each reaction?
These two reactions are: 1. Light reaction or Hill Reaction- in which the photolysis of water takes place to form energy rich compounds like NADPH2 & ATP and O2 is liberated from water. 2. Dark reaction or Blackman reaction- in which the CO2 is assimilated to form carbohydrates by utilizing the energy from the compounds of Hill reaction. It can also be called photosynthesis in the light-dependent stage and light-independent stage (dark stage).
Steps of dark reaction in photosynthesis?
The dark reaction, also known as the Calvin cycle, is the second stage of photosynthesis. It takes place in the stroma of the chloroplast and involves the conversion of carbon dioxide into glucose. The key steps include carbon fixation, reduction, regeneration of RuBP, and production of glucose. These reactions ultimately use ATP and NADPH generated in the light reaction to produce sugar.

Where does photosythsis occur?
Photosynthesis occurs in the choloroplast, a organelle in the cell. More specifically: photosynthesis is divided into several steps. The first step/steps is the light reaction, or light-independent reaction. This happens to absorb the photons, and with it, the energy, from the sun. This part occurs in the thylakoid membranes of the chloroplast. The second part is the Calvin cycle, or the dark/ light-dependent reaction. This part takes the results of the first reaction, and change that energy that was captured into glucose. This occurs in the grana of the choloroplast.

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.
What are the steps in light-dependent reaction?
Oxygen turns into six part carbon sugars
How does photosynthesis start and what are the initial steps involved in the process?
Photosynthesis begins when sunlight is absorbed by chlorophyll in plant cells. The initial steps involve capturing light energy and converting it into chemical energy in the form of ATP and NADPH. This process is known as the light-dependent reactions, which take place in the thylakoid membranes of chloroplasts.
Is light needed for all the steps of photosynthesis?
no

What is the four steps in photosynthesis?
Four steps of photosynthesis: 1. Light absorption via chlorophyll in the chloroplast and electrons comes from water producing oxygen 2. Electron transport - NADPH is formed 3. Generate ATP 4. Convert carbon dioxide into carbohydrates
What are the two steps in photosynthisis?
The two steps in photosynthesis are the light-dependent reactions, which occur in the thylakoid membranes and require light to produce ATP and NADPH, and the light-independent reactions (Calvin cycle) that occur in the stroma and use ATP and NADPH to convert CO2 into sugar.
