Verified step by step guidance

Understand the concept of light-dependent reactions: In organic chemistry, certain reactions require light to proceed. These are typically photochemical reactions where light energy is absorbed by molecules, leading to chemical changes.

Identify the process of photosynthesis: Photosynthesis is a well-known light-dependent reaction. It occurs in plants, algae, and some bacteria, where light energy is converted into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Differentiate between the given reactions: Hydrolysis, hydrogenation, and esterification are not light-dependent. Hydrolysis involves the breaking of bonds with water, hydrogenation involves the addition of hydrogen, and esterification involves the formation of esters from acids and alcohols, none of which require light.

Recognize the role of light in photosynthesis: During photosynthesis, chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose and oxygen. This process is crucial for the survival of plants and the production of oxygen.

Conclude that photosynthesis is the light-dependent reaction among the options provided: Based on the understanding of these reactions, photosynthesis is the only one that requires light to proceed, making it the correct answer.
