masalah 2
jawapan pendek
What is the NAME of the potential generated at motor end plate / sarcolemma, after the membrane depolarised?
End Plate Potential
End plate potential
end plate potential
masalah 3
pilihan
If threshold potential is reached, action potentials will be generated along the sarcolemma.
What would happen next?
- The voltage – gated channel Ca2+ on sarcoplasmic reticulum will open.
- The action potential will spread down the T— tubules to sarcoplasmic reticulum.
- End Plate Potential will be generated.
- Ca2+ will diffuse out of the sarcoplasmic reticulum to sarcoplasm

B) The voltage – gated channel Ca2+ will open.
C) Action potential spread down the T— tubules to sarcoplasmic reticulum.
- B > A > C
- A > B > C
- C > A > B

masalah 6
jawapan pendek
__ binds to __ complex (on actin filament), causing troponin to change its conformation. __ will be pushed away, exposing __ binding site on __.
Write the answers using SPACE ONLY. No need comma.
Ca2+ troponin tropomyosin myosin actin
ca2+ troponin tropomyosin myosin actin
Ca2+ troponin tropomyosin myosin actin
ca2+ troponin tropomyosin myosin actin

The high-energy myosin will then bind to the exposed __ binding site on actin, forming __. Next, __+ Pi will be removed from myosin. Myosin will return to __ energy configuration. Power __ occurs.
- myosin : crossbridge : ATP : low : stroke

After power stroke occurs, __ is pulled to the __ of __. Muscle is __. The next __ will bind to the myosin head, causing the myosin head to __ from actin. Cycle repeats.
