What are we supposed to do?

Answer 5

i dont know how to explain it any deeper thats what it says on my assignment

Answer 6

Are you writing an essay or...?

Answer 7

its gunna be a power point

Answer 8

Light-dependent reaction
The exergonic (energy-releasing) light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the grana (stacks of thylakoids) of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic (energy-requiring) light-independent reactions.

Light-independent reaction
The endergonic (energy-requiring) light-independent reactions of photosynthesis use the ATP and NADPH synthesized during the exergonic (energy-releasing) light-dependent reactions to provide the energy for the synthesis of glucose and other organic molecules from inorganic carbon dioxide and water. This is done by "fixing" carbon atoms from CO2 to the carbon skeletons of existing organic molecules. These reactions occur in the stroma of the chloroplasts.

Answer 9

thx so much

Answer 10

sorry!

Answer 11

what

Answer 12

???

Answer 13

the carbon dioxide that is,CO2 is split into carbon and oxygen ,the some of the oxygen is released and the carbon is mixed with water that is H20,if you construct and equation for the reaction between carbon and water you will see that the product is glucose(sugar)
that is why we say that during photosynthesis plants take in water and carbon dioxide in order to manufacture their food(which is glucose) and to release oxygen
