Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: What does this article say about why birds travel?

Biologists have learned remarkable things about migratory birds’ navigational skills and how they can malfunction because of weather or illness. But these discoveries cannot answer the questions that most interest me. Can a bird travel for curiosity or pleasure, and not just for necessity or instinct? And if it can, how would we know it?

This last question is important, because it’s possible that humans are oblivious to the agency of the nonhuman world around us. In my view, anomalies like this Steller’s can open brief windows beyond our anthropocentrism.

I research environmental humanities and the social dimensions of science, and these questions are currently at the heart of these fields. I believe the extraordinary voyage of this raptor invites us to ask pressing questions about epistemology – how science knows what it knows. It also reveals hidden assumptions on which we rely when we presume that humans alone have the capacity to act for reasons that biology or environment cannot entirely explain.
Response: Biologists have made extraordinary discoveries about how migratory birds navigate and how these navigational skills can become impaired by illness or weather. However, it's also possible that birds may travel for reasons apart from instinct and necessity, like pleasure or curiosity. The example of the Steller's raptor traveling much farther than normal could indicate that some animals act for reasons not entirely explained by biology or their environment.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

How do enzymes facilitate biochemical reactions?
user
Enzymes act as catalysts in biochemical reactions, meaning they lower the activation energy required for a reaction to occur. By providing an active site where specific substrate molecules can bind, enzymes speed up reactions that are essential for cellular function without being consumed in the process.
