Question

The ________ photosynthetic reactions convert light energy into chemical energy, which is stored in molecules like atp. in the _________ photosynthetic reactions, this energy is used to convert co2 into carbon sugars.
a.light dependent; chloroplast
b.chloroplast; light independent
c.light dependent; light independent
d.light independent; light dependent

Answer 1

Answer: Option C.light dependent; light independent

Explanation:

Photosynthesis is the process by which plants make there own food in the presence of sunlight by utilizing carbon-dioxide and water and produce energy in the form of glucose.

The photosynthesis process takes place in two sequential stages called light dependent reactions and light-independent reactions.

The light dependent reaction takes place in the grana, in which light is directly trapped from sun and make energy stored in the form ATP and water molecule split into oxygen, hydrogen ions and free electrons. these free electrons further reduced to NADPH fromnicotinamide adenine dinucleotide phosphate (NADP).

The light-independent reactions occurs in the stroma of the chloroplasts, where ATP and NADPH, are utilised and produces carbohydrates from carbon dioxide.

Hence, the correct option C.

Answer 2

The _light dependent_ photosynthetic reactions convert light energy into chemical energy, which is stored in molecules like ATP.
In the _light independent_ photosynthetic reactions, this energy is used to convert CO2 into carbon sugars.

C. light dependent; light independent
