Which reactions require oxygen as a raw material 1 light reactions only 2 dark reactions only 3 both light and dark reactions 4 niether light or dark reactions?
The light reactions of photosynthesis require oxygen as a raw material to produce ATP and NADPH. The dark reactions (Calvin cycle) of photosynthesis do not directly require oxygen as a raw material, but they use the ATP and NADPH produced in the light reactions. Both light and dark reactions are involved in photosynthesis, but only the light reactions require oxygen as a raw material.
Which of the following photosynthetic reactions describe the reactions in which photolysis occurs?
Photolysis occurs in the light-dependent reactions of photosynthesis. These reactions include the light absorption by chlorophyll, splitting of water into oxygen and protons, and the generation of ATP and NADPH.
What two reactions occur in photosynthesis?
There are three carbon dioxide, water, and sunlight.
Does the dark reactions of photosynthesis release oxygen?
Molecular oxygen is formed in the light dependent reaction of photosynthesis. This occurs in the electron transport chain in the protein complexes of the thylakoid membrane. The water splitting complex yields oxygen, hydrogen ions and electrons.
The place where light reactions occur in a plant?
it occurs in the chloroplast / stroma oh and light reactions can only occur in a plant and some protists because only plants and some protists can perform photosynthesis, and it is in this process which light reactions occur. other cells don't have chloroplast and stromas.
What is wrong in saying that dark reaction of photosynthesis occurs at night?
The so-called "dark reactions" are those that occur independently of the absorption of sunlight, but only when the "light reactions" are providing the molecules required. This only occurs when there is sunlight available.
Where do light reactions occur in photosynthesis?
Only when there is the presence of oxygen.

What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
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 :)
The dark reactions of photosynthesis are those that?
The dark reactions of photosynthesis, also known as the Calvin cycle, occur in the stroma of the chloroplast and do not require light energy. They involve the conversion of carbon dioxide into glucose through a series of enzymatic reactions. The dark reactions use the products of the light reactions, ATP and NADPH, as sources of energy and reducing power.
Which of the following photosynthetic reactions describe the reactions in which photolysis occurs?
Photolysis occurs in the light-dependent reactions of photosynthesis. These reactions include the light absorption by chlorophyll, splitting of water into oxygen and protons, and the generation of ATP and NADPH.
When does photosynthesis happen night or day?
Most types of photosynthesis (C3 & C4) occur only during the day, however plants that use CAM photosynthesis open their stomata during the night to take in the gases essential for photosynthesis withoug losing the water in the cells. They then use the CO2 to produce glucose throughout the day.
True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?
False. The light reactions of photosynthesis require light to convert solar energy into chemical energy, while the dark reactions (Calvin cycle) do not directly rely on light and can occur in both light and dark conditions. However, the dark reactions are indirectly dependent on the products of the light reactions.
