A muscle cell will contain more of this organelle.
What is mitochondria
100
The attachment of a ligand to a receptor forms a dimer, active dimers transfer phosphates to other proteins which produce a response
What is tyrosine kinases
100
The stage in which the cell spends the majority of its time and performs the majority of its purposes including preparation for cell division
What is interphase
100
This is the shortest phase of the cell cycle
What is mitosis
100
the phase of mitosis in which the chromosomes align in the equator of the cell before seperation.
What is metaphase
200
organelle that aids in metabolism of fatty acids
What is a peroxisome
200
an influx of ions trigger a cellular response
What are ligand-gated ion channels?
200
The phase in mitosis in which the chromatin condense into chromosomes
What is prophase
200
During this stage DNA is replicated
What is the S phase
200
this organelle is responsible for producing proteins.
What are ribosomes
300
this organelle maintains cellular structure and plays a role in intracellular transport.
What is the cytoskeleton
300
proteins activated by the transfer of a phosphate from a molecule of GTP
What is G protein linked reception?
300
The final phase of mitosis in which the nuclear membrane forms inside the two new daughter cells.
What is telophase
300
The phase in which a cell has stopped dividing.
What is the G0 phase
300
A signal activates a series of "suicide" enzymes in the cell
What is Apoptosis
400
these organelles play an important role in cell division
What are centrioles
400
Small, non protein water soluble molecules or ions that initiate a phosphorylation cascade
What are second messengers?
400
phase of meiosis in which the chromosomes split so that a chromosome with only one chromatid goes toward each pole
What is anaphase II
400
Phase of rapid cell growth and protein synthesis as the cell gets ready for mitosis
What is the G2 phase
400
cells in the stomach and intestines have an excess of this organelle.
What are lysosomes
500
To enter or leave a cell, substances must pass through this.
What is the cell membrane
500
This occurs when an extracellular signaling molecule activates a cell surface receptor. In turn, this receptor alters intracellular molecules creating a response.
What is a signal transduction pathway
500
phase in meiosis in which chromosomes with only one chromatid decondense and get surrounded by nuclear envelopes
What is telophase II
500
Phase in which cells increase in size, produce RNA, and synthesize proteins.
