bio test 3 - lecture 4 Flashcards
(11 cards)
- According to the video Cell Transport (Amoeba Sisters), which statement describes the basics of active transport?
ATP can power Active Transport to force those molecules to go against their concentration gradient, and one way it can do that is actually energizing the transport protein itself.
- According to the video Cell Transport (Amoeba Sisters), what is endocytosis?
-that’s a large carbohydrate, may need the cell membrane to fuse with
the molecules it’s taking in to bring it inside.
-Endocytosis is a general term, but there are actually different types of endocytosis depending on how the cell is bringing substances inside.
- According to the video Cell Transport (Amoeba Sisters), what is exocytosis?
-Exocytosis can also be used to get rid of cell waste but it’s also really important for getting important materials out that the cell has made.
- According to the video Intro to Cell Signaling, what takes place during the second stage of cell signaling called transduction?
The receptor gets activated by the binding
Receptor will change shape
Involve a series of molecules change their conformation into → Signal transduction pathway
- According to the video Intro to Cell Signaling, what takes place during the third stage of cell signaling called response?
A portion of DNA that is found in the nucleus getting transcribed for example, that’s a type of response.
- According to the video Intro to Cell Signaling, what is the main difference between intracellular and intercellular signaling?
intracellular signaling—which occurs within the cell itself— and intercellular signaling where a cell communicates with another cell.
- According to the video Intro to Cell Signaling, ________signaling allows a cell to target another cell by a signal molecule that may diffuse between them. These cells are still close, but need not be connected. Fill in the blank.
- According to the video Intro to Cell Signaling, paracrine signaling allows a cell to target another cell by a signal molecule that may diffuse between them. These cells are still close, but need not be connected. Fill in the blank.
- According to the video Intro to Cell Signaling, ________ signaling which specifically involves neurotransmitters in a synapse is another example of local signaling. Fill in the blank.
- According to the video Intro to Cell Signaling, synaptic signaling which specifically involves neurotransmitters in a synapse is another example of local signaling. Fill in the blank.
- According to the video Intro to Cell Signaling, ______ signaling can allow a cell to communicate with a target cell from far away. Fill in the blank.
- According to the video Intro to Cell Signaling, endocrine signaling can allow a cell to communicate with a target cell from far away. Fill in the blank.
- According to the video Intro to Cell Signaling, ______________ signaling is when a cell signals itself. For example, a cell could secrete a certain type of molecule which then binds to its own receptor and causes a response. Fill in the blank.
- According to the video Intro to Cell Signaling, ______intracellular_________ signaling is when a cell signals itself. For example, a cell could secrete a certain type of molecule which then binds to its own receptor and causes a response. Fill in the blank.
- According to the video Intro to Cell Signaling, _______ is an example of a disease that can involve body cells with problems in cell signaling. Fill in the blank.
- According to the video Intro to Cell Signaling, cancer is an example of a disease that can involve body cells with problems in cell signaling. Fill in the blank.
