Quiz 4

Troponin C when bound to Ca++ loosens its "grip" on Tropomyosin that in turns exposes binding sites on the actin filament.
True False

A side effect of a beta-blocker can be weight gain.
True False

COMT recycles acetylchloline
True False

Synaptobrevin is a recognition protein found on vesicular membrane.
True False

Presynaptic membranes will have vgc for Ca++ and a recognition protein like syntaxin
True False

The effect of atropine on the heart is to slow it down or negative chronotropic effect.
True False

Creatine is needed the actin-myosin site for contraction and relaxation.
True False

Creatinine is a breakdown product when ATP produced in the electron transport chain.
True False

Lack of Dystrophin is found in Myesthenia Gravis
True False

EPSPs and IPSPs summate to produce an overall post synaptic response.
True False

EPSP are produced by activation of Na+ lgc and IPSPs are produced by activating K+ or Cl- lgc.
True False

Neostigmine is an agent used as cholinesterase inhibitor.
True False

Paralysis of voluntary muscle can be caused by a nicotinic cholinergic blocker
True False

Beta blockers would increase heart rate and contractility
True False

A cholinergic muscarinic blocker would increase heart rate.
True False

there are net 38 ATPs produced from one molecule of Glucose after the 2 ATP used by the cell are deducted from the total ATP production
True False

Amino acids can replace acetyl-SCoA by deamination.
True False

The proton pump is "powered" by the transfer of electrons down the electrons transfer chain.
True False

Chemiosmosis occurs in the Kreb's cycle.
True False

MAOI can be additive in their effects with CNS depressants.
True False

For every myosin "think filament" there are 6 actin "thin filament."
True False

the H zone changes with contraction and relaxation but the A band stays fixed.
True False

There are no myosin heads in the region of the H zone.
True False
