PLEASE HURRY TIMED Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? a) The energy input required for making organic compounds equals the usable energy output of respiration.

b) The energy required from sunlight to start photosynthesis is less than the energy needed from another energy source.

c) The energy required to make organic compounds is always greater than the potential energy stored in these compounds.

d) The energy that a plant absorbs from sunlight is spontaneously transformed into chemical energy because the outputs are more stable.

C i believe

Explanation:

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
