Photosynthesis occurs in two sets of reactions within the chloroplast: light-dependent reactions
and light-independent (dark) reactions.
Light-dependent reactions occur inside grana, which are stacks of membrane-bound disks
found within chloroplasts. What is the main purpose of the light-dependent reactions?
A.
to produce sugar molecules using ATP, NADPH, and CO2
B. to convert light energy into the chemical energy of ATP and NADPH
C. to produce water using oxygen from the air
D. to convert light energy directly into glucose molecules

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
