FMS Year 1

2. Network of protein filaments that maintains cell shape and provides structural support.
5. Calcium pump that returns calcium to the sarcoplasmic reticulum during relaxation. Give its acronym.
7. Stage of signalling that relays a receptor signal through intracellular molecules.
10. Organelle mainly responsible for ATP production through oxidative phosphorylation.
13. Functional contractile unit extending between two neighbouring Z discs.
16. Neurotransmitter released by a motor neuron at the skeletal neuromuscular junction.
17. Protein whose C subunit binds calcium to help expose myosin-binding sites on actin.
19. Process by which synaptic vesicles release their contents into the synaptic cleft.
21. Transport system that moves two substances through the same carrier in the same direction.
22. Region containing DNA in a prokaryotic cell.

1. Signalling in which a chemical messenger acts on nearby cells.
3. Type of conduction in which action potentials are regenerated at successive nodes of Ranvier.
4. Change in membrane potential towards a less negative value.
6. Type of diffusion used when glucose enters a cell through a GLUT transporter.
7. Protein that covers the myosin-binding sites on actin in a resting skeletal muscle.
8. Type of acetylcholine receptor found on the skeletal muscle motor end plate.
9. Membrane potential level that must be reached to trigger an action potential.
11. Ion whose entry into the motor nerve terminal triggers neurotransmitter release.
12. Type of active transport that uses energy stored in an ion gradient.
14. Signalling in which hormones travel through the bloodstream to distant target cells.
15. Movement of water across a selectively permeable membrane in response to an osmotic gradient.
16. Signalling in which a chemical messenger acts on the same cell that released it.
18. Programmed cell death that normally removes tissue between developing fingers.
20. Ion to which the neuronal membrane is most permeable at rest.
