What Is Life? 2nd Edition by Jay Phelan

Exercise 54

The leaves of plants can be thought of as "eating" sunlight. From an energetic perspective, this makes sense because:
A) light energy, like chemical energy released when the bonds of food molecules are broken, is a type of kinetic energy.
B) both light energy and food energy can be converted to kinetic energy without the loss of heat.
C) the carbon-oxygen bonds within a photon of light release energy when broken by the enzymes in chloroplasts.
D) the carbon-hydrogen bonds within a photon of light release energy when broken by the enzymes in chloroplasts.
E) photons are linked together by hydrogen bonds, which release energy when striking the surface of a leaf.
