Other questions in this quiz

2. What is Ca2+ role in muscle contraction?

  • binds to actin to enable myosin to binds to binding sites of troponin
  • binds to myosin binding sites
  • binds to troponin, causing the shift in tropomyosin to expose myosin binding sites
  • binds to tropomyosin, causing it to shift away from the myosin binding sites

3. The Na+ gate is:

  • Voltage-gated
  • G-protein gated
  • Open all the time
  • Impermeable

4. which ions act as ESPS and trigger depolarisation of ligand gated channels?

  • cations
  • neions
  • anions
  • dogions

5. Which receptor type detects pressure stimuli

  • chemoreceptors
  • mechanoreceptors
  • nociceptors
  • thermoreceptors
