Question

the chloroplasts of a photosynthetic cell transform solar energy into chemical energy in the form of glucose. this transformation of energy from kinetic to potential demonstrates: decreasing entropy the first law of thermodynamics the second law of thermodynamics feedback inhibition enthalpy

Explanation:

• The first law of thermodynamics (law of conservation of energy) states that energy can neither be created nor destroyed, but can be transformed from one form to another. In photosynthesis, solar energy (kinetic) is transformed into chemical energy (potential) in glucose, which is an example of energy transformation as per this law.
• Decreasing entropy: Entropy is a measure of disorder. While photosynthesis creates order (glucose), the overall entropy of the universe still increases (as the sun is losing energy and becoming more disordered). But the question is about energy transformation, not entropy change.
• The second law of thermodynamics is about entropy increase in the universe.
• Feedback inhibition is a regulatory mechanism in metabolic pathways.
• Enthalpy is the total heat content of a system.

Answer:

the first law of thermodynamics
