. Draw a cardiac action potential and indicate on the graph the channels and ions responsible for each phase of the cardiac action potential and whether these ions are moving into (influx) cardiac contractile cells or out (efflux) of cardiac contractile cells.

Why would cardiac glycosides (Na+/K+ ATP-ase inhibitors) be used to increase cardiac contractile force in a patient with heart failure? Group of answer choices Reducing the concentration gradient for Na+ would cause a larger depolarisation during an action potential, hence releasing more intracellular Ca2+ stores. Reducing the concentration gradient for Na+ would inhibit the action of the Na+/Ca2+ exchanger, increasing intracellular Ca2+ concentrations. Inhibiting this pump would lead to a reduction in the ATP requirements for the cell, allowing it...

In lecture, we drew and labeled a graph showing change in membrane potential as an axon fires an action potential. a. In the space below, draw what the graph would look like if a neurotoxin that kept the Na+-gated channels open was administered to a nerve cell. b. What do you think would happen to the K+-gated channels in the situation mentioned in the question above? Explain why.

Consider four preparations, each with a chamber containing a mystery muscle fibre connected to a force transducer and a stimulating electrode. You are able to: Stimulate the muscle fibre and cause an action potential Each of the four preparations contain a different type of muscle fiber: A slow-twitch skeletal muscle fibre A cardiac contractile cell A cardiac autorhythmic cell Describe how you would go about determining which type of muscle fibre is in the chamber.

Consider four preparations, each with a chamber containing a mystery muscle fibre connected to a force transducer and a stimulating electrode. You are able to: Stimulate the muscle fibre and cause an action potential Vary stimulation frequency and amplitude Measure the contractile force of the muscle fibre but NOT the duration (don’t ask me why. You bought the cheapest force transducer they had at K-Mart). Change the composition of the artificial extracellular fluid in the muscle chamber i.e. add or...

In a two-compartment model of a cell with a K+- and Na+-permeable membrane and a 10-fold excess of K+ in the inside compartment, how would the membrane potential change if all K+ ions were replaced by Na+ ions? a. It would double. b. It would be reduced by half. c. It would not change. d. It would become positive. e. No potential would be generated.
