AP Biology Unit 4 Review

Front

What are the three parts of a signal transduction pathway?

Back

Reception, Transduction, Response

Front

What occurs during anaphase in mitosis?

Back

Sister chromatids are separated and kinetochores begin pulling chromosomes to opposite poles.

Front

What role do secondary messengers play in cell signaling?

Back

They activate or deactivate enzymes during the transduction step.

Front

Which of the following is NOT a stage of the cell cycle?

Back

Apoptosis.

Front

What phase of mitosis involves the separation of sister chromatids?

Back

Anaphase.

Front

Define reception in the context of cell signaling.

Back

The initial step where a signaling molecule binds to a receptor on a target cell.

Front

What is transduction in cell signaling?

Back

The process by which a signal is converted into a functional response within the cell.

Front

What is the response in a signal transduction pathway?

Back

The final outcome of the signaling process, which may involve changes in gene expression or cellular activity.

Front

What is interphase?

Back

The phase of the cell cycle where the cell prepares for division, including DNA replication.

Front

What happens during cytokinesis?

Back

The division of the cytoplasm, resulting in two separate daughter cells.
