light and water.

energy from the sun (light) is absorbed by photosystems I and II and used to energize the electrons whose energy is later used to make the molecules that act as energy carriers ATP (adenosine triphosphate) and the electron carrier NADPH.

Water molecules (H20) are used in photosystem II (note that photosystem II comes first in the process then photosystem I because they were named according to the order by which they were discovered). Enzymes break down water into hydrogen ions (H+), electrons (that replace those that left photosystem II-chlorophyll and other light-absorbing molecules- when energy from sunlight was absorbed), and oxygen molecules (which are given off as a waste product).

What is the difference between the light dependent reactions and the light independent reactions?

light dependent reactions only occur in light this means thier reations increases with light intensity while light independent can occur in the dark

What are light independent and dependent reactions?

Light dependent reactions are reactions the capture light energy and convert it into chemical energy(ATP). It occur in the chloroplast of plant cells Light independent reactions are reactions capture energy and use it to produce food . It does not need sunlight


What is another name for the dark reactions of photosynthesis?

Calvin cycle or light independent reaction


What light-independent reactions do plants produce?

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.


Can the light dependant reactions occur without the light independent reactions?

No, the light-dependent reactions in photosynthesis cannot occur without the light-independent reactions. The light-dependent reactions, which take place in the thylakoid membranes of chloroplasts, require light energy to produce ATP and NADPH. These molecules are then used in the light-independent reactions (Calvin cycle) to convert carbon dioxide into glucose. Thus, both sets of reactions are interdependent and necessary for the complete process of photosynthesis.


Are the reactions of photosynthesis?

What are the products in the independent reactions?

The light independent reaction produces Glucose
