Final answer:
The order of signal transduction pathway steps is signal reception, signal transduction, and cellular response.
Step-by-step explanation:
- Signal reception
- Signal transduction
- Cellular response
In signal transduction pathways, the sequence of events typically starts with signal reception, where a cell receives a signal from its environment. Next, the signal is transmitted within the cell through a series of molecular interactions in the process called signal transduction. Finally, the cellular response occurs, which can include various cellular activities or changes in gene expression.
For example, when a hormone binds to a receptor on the surface of a cell, it triggers a signaling cascade inside the cell, leading to a specific cellular response. This could be the activation of an enzyme, changes in gene expression, or cell division, among other possibilities.
