1 Curare is a poisonous plant extract Curare molecules have a chemical structure like the neurotransmitter ACh Curare can bind to the ACh receptor site on the chemically gated ion channels in the motor end plate Even though curare will bind to the receptor site it will not open the ion channel and no ions will pass through What do you think the symptoms of curare poisoning would look like A Muscles will respond too uickly and cause a severe tremor B Curare will only affect cardiac muscle causing fibrillations of the heart C Curare will only affect muscles with ACh receptors paralyzing them D Smooth muscles will become stimulated causing quick movement of nutrients through the digestive system 2 Addition of more mitochondria to a muscle fiber will have the least effect on A slow oxidative fibers B fast glycolytic fibers C both slow and fast oxidative fibers D fast oxidative fibers 3 The thin filaments are not comprised of which of the following components A Actin B Titin Troponin Tropomyosin C D 4 At the neuromuscular junction the muscle contraction initiation event is A a release of calcium ions from the sarcoplasmic reticulum B conduction of an electrical impulse down the T tubules C binding of acetylcholine to membrane receptors on the sarcolemma D sliding of actin and myosin filaments past each other

back into ATP O immediately during sustained contraction during the recovery period Question 23 1 point Listen Fatty acids can be used as an energy source for immediate replenishment of ATP glycolytic catabolism oxidative catabolism Question 24 1 point

vhich neurotransm phase acetylcholine dopamine serotonin neuropeptide Y Question 21 1 point 4 Listen Which regulatory protein does calcium bind to in skeletal muscle fibers actin myosin tropomyosin

Which of these structures stores calcium a the sarcolemma b the sarcoplasmic reticulum O c the nuclei d the rough endoplasmic reticulum Question 18 1 point Listen T tubules are formed of the of the myocyte a sarcolemma

When muscles contract producing muscle tension they are taking energy and turning it into energy kinetic mechanical light electrical chemical potential chemical mechanical Question 14 1 point 4 Listen The extracellular matrix around the muscle cell is called endomysium Operimysium

Calcium ions bind to the regulatory protein actin myosin Otropomyosin tronanin

Turn to The Big Picture of Skeletal Muscle Contraction Figure 10 20 FYI there is also an animation on Mastering A P Put the five stages of skeletal muscle contraction in order 5 ww 4 2 1 3 V relaxation contraction excitation preparation for contraction excitation contraction coupling

How many ATP are required for each turn of the crossbridge cycle zero one two four

The crossbridge cycle which moves the thick filaments along the thin filaments shortening the sarcomere involves repeatedly binding to the myosin heads bind to troponin the myosin heads bind to the myosin tail the myosin heads bind to the actin active site the myosin heads bind to the tropomyosin

Those calcium ions bind to troponin causing tropomyosin to move which exposes the active sites of the contractile protein O actin hemoglobin myoglobin myosin

Sodium ions moving into the cell trigger an action potential on the muscle cell The action potential sweeps across the muscle cell and down the T tubule This then causes release of ions from the terminal cisternae of the sarcoplasmic reticulum look at Figure 10 16 calcium potassium sodium

Once the acetylcholine binds to its receptor on the motor end plate that receptor is activated it opens and ions move into the myocyte calcium potassium sodium

Indigenous Andean people from Chile and Argentina have been exposed to arsenic over 7 000 years They have a unique genetic mutation in the AS3MT gene which is the coding gene of the Arsenic 3 Methyltransferase enzyme that allows them to metabolize arsenic very well in the liver Indeed geneticists have found the genotype frequency for that mutation is CC 80 and these populations are NOT under Hardy Weinberg equilibrium Which of the following is the main evolutionary force acting in these populations Gene flow Natural selection Genetic drift None of the answers are correct Random mating
