Cell Signaling
What are the 3 steps in the signal transduction pathway?
What are a reception, transduction, and response
What happens during Cytokinesis to an animal cell? Plant cell?
Cytoplasm is pinched into two nearly equal parts (cleavage furrow) or a cell plate (line of vacuoles) forms midway between the divided nuclei.
What is the term for short distance signaling?
What is paracrine
What is a family of proteins that control the progression of cells through the cell cycle by activating cyclin-dependent kinase (Cdk) enzymes.
What is a cyclin
The type of feedback loop that pushes an organism further away from homeostasis (ex. labor)
What is positive feedback loop?
What is a signal molecule that binds to a larger molecule on the cell's surface.
What is a ligand
What stage of the cell cycle does our DNA replicate?
The term for long distance signaling
What is endocrine
How many checkpoints are involved in the regulation of the cell cycle?
What is 3
The type of feedback loop that brings the organism closer to homeostasis.
What is negative feedback loop?
What happens after a ligand binds to its receptor?
What is protein modification/shape change?
What are the 3 steps of interphase and 4 steps of mitosis?
What are G1, S, G2, Prophase, Metaphase, Anaphase, Telophase.
The term for a cell communicating with itself
What is autocrine
What checkpoint decides whether or not the cell will undergo division or enter the G0 phase?
What is G1?
What type of farm did Taylor Swift grow up on?
What is a Christmas tree farm?
What type of receptor forms a dimer when activated?
What is a tyrosine kinase receptor?
Two new nuclei form during this stage of Mitosis.
What is Telophase?
The term for cell communication through direct contact
What is direct or juxtacrine.
What is apoptosis?
What is controlled cell death?
What is the Speak Now album color?
What is violet?
What is a series of chemical reactions during cell signaling mediated by enzymes, in which each kinase in turn phosphorylates and activates another?
What is Phosphorylation Cascade
At what point in the cell cycle do the sister chromatids separate?
What is Anaphase
What are the structures that allow direct contact between animal and plant cells?
What are gap junctions and plasmodesmata.
What processes cause cancer?
What is the accumulation of mutations in genetic material/uncontrolled cell growth
Accumulation of which molecule triggers a cell's passage through the G2 checkpoint and into mitosis?
What is MPF (maturation promoting factor)?
