ReLEARNing - Overview of Cell Signaling

How are animal cell gap junctions different from plant cell's plasmodesmata?

• Animal cells do not come into contact each other

• Animal cells have junctions through cell walls while plants cells do not

• Plant cells do not come into contact with one another

• Plant cells have junctions through cell walls while animal cells do not

What structure of the cell do the circles represent?

• Nucleus

• Ribosomes

• Cell membrane

What type of cell, involved in phagocytosis, might have this type of direct contact with other cells in the blood stream?

• White blood cell

• Muscle cell

• Bone marrow

• Red blood cell

What type of active transport releases materials using a vesicle?

• Simple diffusion

• Exocytosis

• Endocytosis

• Passive transport

What happens to a cell if it does not have the receptor that matches the signal?

• The cell dies

• The cell does not have a response

• The cell makes its own signal

Which two cells might use paracrine signaling to communicate

• A skin cell on your face and a skin cell on your foot

• A brain cell and a heart muscle cell

• A liver cell and skin cell

• Two skin cells on your finger

Hormones are used for what type of cell signaling?

• Paracrine

• Direct contact

• Endocrine

Based on how autocrine singaling works what does the prefix "auto" mean?

• Self

• Many

• Pickle

• Other

What is the most likely response to transduction?

• activate or inhibit transcription of the DNA

• produce more cell membrane receptors

• make more ATP

• transduction doesn't make anything happen in the cell

What is the correct order for cell signaling?

• Reception -> Transduction -> Response

• Response -> Reception ->Transduction

• Transduction - > Reception -> Response
