Question 12 • EDG CHEM ES W/LABS2(P) – Q2_9

During photosynthesis, sunlight shining on a plant is absorbed. Through several chemical reactions, the plant produces sugar, a high-energy compound, from simpler substances. What energy transformation occurs during this process?

Answer
A
thermal energy to chemical energy
B
electromagnetic energy to chemical energy
C
kinetic energy to potential energy
D
potential energy to chemical energy

Explanation

Sunlight carries electromagnetic energy. During photosynthesis, the plant uses that light energy to make sugar, storing energy in the sugar’s chemical bonds. So the transformation is electromagnetic energy to chemical energy.
