Unit 4 AP Biology Insta-Review (Cell Communication & Cell Cycle)

Front

What does cytokinesis divide?

Back

Cytoplasm

Front

If a cell doesn’t receive the go-ahead signal in G1, where does it go?

Back

G0

Front

Where is calcium stored in muscle cells?

Back

Smooth ER

Front

What does mitosis divide?

Back

Nucleus

Front

What type of signal binds to the secreting cell?

Back

Autocrine

Front

What is the role of the Smooth Endoplasmic Reticulum (Smooth ER)?

Back

The Smooth ER is involved in the storage of calcium ions and lipid synthesis.

Front

What is the function of the G1 phase in the cell cycle?

Back

The G1 phase is where the cell grows and prepares for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase is where the cell continues to grow and prepares for mitosis.

Front

What is the difference between autocrine and paracrine signaling?

Back

Autocrine signaling affects the same cell that secretes the signal, while paracrine signaling affects nearby cells.
