Let's start by restating the question and the provided choices to ensure we understand the setup.
Question: Insulin binds to specific receptors on the plasma membranes of its target cells. This binding triggers _____ pathways that influence transport proteins and intracellular enzymes of the target cell.
Answer options: 空白1, 空白2
Now, evaluating each option:
Option 空白1: This choice is just the label for the first blank and does not specify the actual word to fill in. As a result, it cannot convey the intended biochemical concept, which is to name a type of cellular process. Without the content, we cannot assess its accuracy relative to the stem.
Option 空白2: Similarly, this option is merely the second blank label and also lacks the concrete term that completes the sentence. Like 空白1, it fails to provide the specific pathway name needed to describe how insulin signaling operates within cells.
Given that both options are placeholders and do not supply the actual term, we cannot evaluate them as correct or incorrect in terms of scientific meaning. However, the standard biological concept that completes the sentence is the word signaling, specifically signaling pathways triggered by receptor binding that modulate transport proteins and intracellular enzymes.
To connect the idea to biology, insulin binding to its receptor typically activates intracellular signaling cascades (e.g., PI3K-AKT pathway) that regulate glucose transporter translocation and enzyme activities, thereby influencing cellular transport and metabolism. Misconceptions to avoid include:
- Thinking only about membrane transport without signaling context. Insulin action is mediated through signaling cascades, not just direct transporter binding.
- Assuming multiple unrelated processes are invoked by insulin; the canonical description emphasizes signaling pathways that coordinate metabolic responses.
- Confusing signaling with a single, isolated event; in reality, signaling involves cascades with multiple intermediates and cross-talk that fine-tune cellular responses.
In summary, neither 空白1 nor 空白2 provides the needed term. The appropriate fill would be signaling to describe the cascade of events initiated by insulin receptor engagement that modulates transport proteins and intracellular enzymes.

Insulin binds to specific receptors on the plasma membranes of its target cells. This binding triggers pathways that influence transport proteins and intracellular enzymes of the target cell.
