To accurately answer your question, I would need to know the specific options you're considering regarding the light-dependent reactions of photosynthesis. Generally, the main steps include photon absorption by chlorophyll, water splitting to release oxygen, electron transport chain activity, and ATP/NADPH formation. Any step that does not pertain to these processes would be considered not part of the light-dependent reactions.
What else can I help you with?
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.
What part of photosynthesis generates no ATP from ADP?
The light-dependent reactions in photosynthesis generate oxygen from water. No ATP is produced during this step.
Second step in photosynthesis?
The second step in photosynthesis is the light-dependent reactions, which take place in the thylakoid membranes of the chloroplasts. During this step, light energy is absorbed by chlorophyll and water molecules are split, releasing oxygen as a byproduct. This process generates ATP and NADPH, which are used in the Calvin cycle to produce glucose.
What happens in the thylakoid membranes?
Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). Grana are connected by intergrana or stroma thylakoids, which join granum stacks together as a single functional compartment.
Where do light reactions happen in the chloroplasts?
It take place on thylakoid membranes.It is the first step.

What part of photosynthesis generates no ATP from ADP?
The light-dependent reactions in photosynthesis generate oxygen from water. No ATP is produced during this step.
How are light reactions and dark reactions similar and different?
Differences: >light reactions occur in the thykaloid membranes, but dark occur in stroma >light reactions are light dependent, or they need light to take place, whereas dark reactions don't > dark reactions use the products of the light reactions >light reactions are the first step of photosynthesis and dark reactions are the second step Similarities: >both in photosynthesis Thats really the only similarity!!! hope this helps :)
Second step in photosynthesis?
The second step in photosynthesis is the light-dependent reactions, which take place in the thylakoid membranes of the chloroplasts. During this step, light energy is absorbed by chlorophyll and water molecules are split, releasing oxygen as a byproduct. This process generates ATP and NADPH, which are used in the Calvin cycle to produce glucose.
What are light dependent reactions of photosynthesis also known as?
Light dependent reactions of photosynthesis are also known as the light reactions. These reactions occur in the thylakoid membranes of chloroplasts and involve the absorption of light energy to produce ATP and NADPH, which are used in the Calvin cycle to generate glucose. Oxygen is also produced as a byproduct of these reactions.
What is the first step to photosynthesis?
Light Dependant Reactions
Why are the reactions of the calvin cycle also called the light independent reaction?
Well, darling, they call it the light-independent reaction because unlike photosynthesis where light is needed, the Calvin Cycle doesn't give a damn about the sun. It's all about using that stored up energy from the light-dependent reactions to fix carbon dioxide and make some sugar. So, in a nutshell, it's like saying, "I don't need no stinkin' light to do my job!"
Where do the two stages of photosynthesis occur?
The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
What are the dark reactions?
It is photosynthesis where light is not needed. It is a nickname for the Calvin-Benson cycle which is the second main step of photosynthesis. It utilizes the ATP and NADPH produced from the light-reactions as well as carbon dioxide from the air in order to produce glucose.
What step of photosynthesis is glucose produced?
Glucose is produced during the Calvin cycle, which is also known as the light-independent reactions of photosynthesis. This process takes place in the stroma of the chloroplasts and requires ATP and NADPH generated during the light-dependent reactions.
