Unit 4 Cell Communication and the Cell Cycle Study Guide Flashcards

Flashcards covering key concepts from Unit 4: Cell Communication and the Cell Cycle. These flashcards cover cell signaling, homeostasis, and the cell cycle.

Cell Communication and Replication

Cells use energy and information transmission to communicate and replicate.

Cellular Response

Cells generate and receive signals, coordinate mechanisms for growth, and respond to environmental cues.

Homeostasis

Cells respond to their environment to maintain homeostasis.

Signal Transduction and Gene Expression

Signal molecules bind to receptors, and gene expression can be stimulated by signal transduction.

Cell Cycle Disruption

Disruptions in the cell cycle can have various effects on a cell.

Mitosis and Cell Cycle Checkpoints

Mitosis results in the transmission of chromosomes from one generation to the next, and checkpoints regulate the cell cycle.

Cell Communication Distance

Cells communicate with one another over short and long distances.

Signal Transduction Pathway

Components of a signal transduction pathway produce a cellular response.

Environmental Influence

The environment plays a role in eliciting a cellular response.

Signaling Molecule Changes

Changes in signaling molecules affect the activity of the signaling pathway.

Negative Feedback

Negative feedback helps to maintain homeostasis.

Cell Cycle Events

Events occurring in the cell cycle lead to cell division

Cell Cycle Checkpoints

Checkpoints regulate the cell cycle ensuring proper division.

Disruptions to Cell Cycle

Disruptions to the cell cycle can lead to uncontrolled growth or cell death.
