What is the primary function of the light reactions of photosynthesis?
a) to produce energy-rich glucose from carbon dioxide and water
b) to produce atp and nadph
c) to produce nadph used in respiration
d) to convert light energy to the chemical energy of pgal
e) to use atp to make glucose

The correct answer will be option-B.

Explanation:

Photosynthesis occurs in two stages: light-dependent and light-independent reaction.  The light-dependent reaction is the reaction which takes place in the sunlight and converts light energy to chemical energy.

The reaction stores chemical energy in the form of energy equivalents mainly ATP through chemiosmosis and NADPH. These molecules are used in the second phase of the photosynthesis that is light-independent reactions where glucose is synthesized.

Thus, Option-B is the correct answer.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
