Question

A typical flow of information in a signal transduction pathway would be:

Answer 1

In a signal transduction pathway, information flows from the outside of a cell to the inside, resulting in a cellular response.

Step-by-step explanation:

A typical flow of information in a signal transduction pathway involves a series of events that transmits a signal from the outside of a cell to the inside, resulting in a cellular response.

Here is an example:

1. A ligand binds to a receptor on the cell surface.
2. Activation of the receptor initiates a signaling pathway or cascade.
3. Proteins, enzymes, and second messengers interact with specific proteins in a chain reaction.
4. This leads to a change in the cell's environment, such as activation of transcription factors or changes in gene expression.
