Receptors
It is an enzyme-linked receptor.
What type of receptor is the insulin receptor?
Hey, I have a parent and a daughter strand.
What is semiconservative replication?
The four nucleotide bases that make up RNA.
What are A, G, C, and U?
Ca2+ voltage-gated channels.
What voltage-gated channels open when an action potential depolarizes the presynaptic axon terminal?
These help the action potential move quickly between cardiac cells (myocytes).
What are gap junctions?
Estrogen can pass through the cell membrane and bind to this type of receptor in the cytoplasm.
What is a soluble receptor?
Joins Okazaki fragments together during DNA replication.
What is DNA ligase?
Carries the amino acid to a growing polypeptide chain.
What is tRNA?
The area that a neurotransmitter first enters after it has been released from a pre-synaptic neuron.
What is the synapse?
Release of acetylcholine from a pre-synaptic neuron can bind to an open this type of channel that allows Na+ to enter the post-synaptic neuron?
What is a ligand-gated ion channel?
Have seven transmembrane domains and activate fast, varied responses.
What are G-protein coupled receptors (GPCRs)?
What are single-stranded binding proteins?
Contains an anticodon that recognizes a codon on mRNA.
What is tRNA?
Channels that potassium ions (K+) use to move from inside to outside the cell when the cell is at its resting membrane potential.
What are leak channels?
They are down-regulated to minimize protein translation during times of fasting or infection.
What are elongation initiation factors (eIFs)?
Unlike passive diffusion, this type of transport requires energy?
What is primary active transport?
Name given to the tubulin polymers that pull replicated chromosomes apart during cell division?
What are micofilaments?
Is produced in the nucleus but translated in the cytoplasm?
What is mRNA?
Na+ channels close quickly and voltage-gated K+ channels open to allow K+ to leave the cell.
What happens as the action potential of the myocyte reaches its peak?
Activates calmodulin which phosphorylated myosin light chain kinase.
What does Ca2+ do to cause smooth muscle to contract?
The site on DNA that RNA polymerase binds along with transcription factors to initiate gene transcription.
What is a promoter?
These genes are constitutively expressed.
What are genes involve in metabolism of glucose?
Added to the either end of a mRNA molecule to prevent its degradation?
What is 7-methylguanosine and a poly(A) tail?
The number of Na+ and K+ ions the Na+/K+ pump moves across the cell membrane in a single rotation.
What is 3 Na+ and 2 K+.
Neurotransmitter released by the parasympathetic post-ganglionic neuron.
What is acetylcholine?
