Unit Objectives
CED Topic 4.1: Cell Communication
- Describe the ways that cells can communicate with one another.
- Explain how cells communicate with one another over short and long distances.
- Describe the components of a signal transduction pathway.
- Describe the role of components of a signal transduction pathway in producing a cellular response.
- Describe the role of the environment in eliciting a cellular response.
- Describe the different types of cellular responses elicited by a signal transduction pathway.
- Explain how a change in the structure of any signaling molecule affects the activity of the signaling pathway.
- Describe positive and/or negative feedback mechanisms.
- Explain how negative feedback helps to maintain homeostasis.
- Explain how positive feedback affects homeostasis.
- Describe the events that occur in the cell cycle.
- Explain how mitosis results in the transmission of chromosomes from one generation to the next.
- Describe the role of checkpoints in regulating the cell cycle.
- Describe the effects of disruptions to the cell cycle on the cell or organism.
